Analysis of Clinical Utility of Functional MRI in Neurosurgical Decision-Making in Focal Epilepsy.

Functional MRI (fMRI) has proven valuable in presurgical planning for people with brain tumors. However, it is underutilized for patients with epilepsy, likely due to less data on its added clinical value in this population. We reviewed clinical fMRI referrals at the QEII Health Sciences Center (Halifax, Nova Scotia) to determine the impact of fMRI on surgical planning for patients with epilepsy. We focused on reasons for fMRI referrals, findings and clinical decisions based on fMRI findings, as well as postoperative cognitive outcomes. We conducted a retrospective chart review of patients who underwent fMRI between June 2015 and March 2021. Language lateralization represented the primary indication for fMRI (100%), with 7.7% of patients also referred for motor and sensory mapping. Language dominance on the side of resection was observed in 12.8% of patients; in 20.5%, activation was adjacent to the proposed resection site. In 18% of patients, fMRI provided an indication for further invasive testing due to the risk of significant cognitive morbidity (e.g., anterograde amnesia). Further invasive testing was avoided based on fMRI findings in 69.2% of patients. Cognitive outcomes based on combined neuropsychological findings and fMRI-determined language dominance were variable. fMRI in epilepsy was most often required to identify hemispheric language dominance. Although fMRI-determined language dominance was not directly predictive of cognitive outcomes, it helped identify patients at low risk of catastrophic cognitive morbidity and those at high risk who required additional invasive testing.

Imaging the large-scale and cellular response to focal traumatic brain injury in mouse neocortex.

Traumatic brain injury (TBI) affects neural function at the local injury site and also at distant, connected brain areas. However, the real-time neural dynamics in response to injury and subsequent effects on sensory processing and behavior are not fully resolved, especially across a range of spatial scales. We used in vivo calcium imaging in awake, head-restrained male and female mice to measure large-scale and cellular resolution neuronal activation, respectively, in response to a mild/moderate TBI induced by focal controlled cortical impact (CCI) injury of the motor cortex (M1). Widefield imaging revealed an immediate CCI-induced activation at the injury site, followed by a massive slow wave of calcium signal activation that traveled across the majority of the dorsal cortex within approximately 30 s. Correspondingly, two-photon calcium imaging in primary somatosensory cortex (S1) found strong activation of neuropil and neuronal populations during the CCI-induced traveling wave. A depression of calcium signals followed the wave, during which we observed atypical activity of a sparse population of S1 neurons. Longitudinal imaging in the hours and days after CCI revealed increases in the area of whisker-evoked sensory maps at early time points, in parallel to decreases in cortical functional connectivity and behavioral measures. Neural and behavioral changes mostly recovered over hours to days in our M1-TBI model, with a more lasting decrease in the number of active S1 neurons. Our results in unanesthetized mice describe novel spatial and temporal neural adaptations that occur at cortical sites remote to a focal brain injury.

Walking memories, future dreams: Exploring design through cartographies, speculation, and AI

This paper summarizes a design practice (“Take the Memory Out for a Future Walk”) conducted with undergraduate students in a park in Barcelona. Through walking, sensory mapping, artificial intelligence exploration, and prototyping, participants explored the interplay between embodied experiences, memory, future speculation, and design intervention. Walking the park fostered sensory engagement, shaping students’ understanding of the site and its history. This informed the development of projects addressing environmental concerns and promoting sustainable practices through reimagined spaces or objects. Students employed AI tools to generate ideas where they envisioned alternative futures and challenged existing norms. This process encouraged non-canonical reflection, urging students to move beyond conformistic approaches while fostering future-oriented critical thinking. The practice yielded valuable insights for design education. Firstly, it showed why the integrating walking and sensory mapping into design processes can challenge space determinism. In addition, it contributed to the potential of speculative design and future studies to foster alternative imagination and address pressing issues like climate change, promoting planetary awareness. Further iterations could benefit from expanding on-site exploration and incorporating material limitations to deepen student engagement with the natural surroundings, community and project sustainability.

Perceiving depth beyond sight: Evaluating intrinsic and learned cues via a proof of concept sensory substitution method in the visually impaired and sighted.

This study explores spatial perception of depth by employing a novel proof of concept sensory substitution algorithm. The algorithm taps into existing cognitive scaffolds such as language and cross modal correspondences by naming objects in the scene while representing their elevation and depth by manipulation of the auditory properties for each axis. While the representation of verticality utilized a previously tested correspondence with pitch, the representation of depth employed an ecologically inspired manipulation, based on the loss of gain and filtration of higher frequency sounds over distance. The study, involving 40 participants, seven of which were blind (5) or visually impaired (2), investigates the intrinsicness of an ecologically inspired mapping of auditory cues for depth by comparing it to an interchanged condition where the mappings of the two axes are swapped. All participants successfully learned to use the algorithm following a very brief period of training, with the blind and visually impaired participants showing similar levels of success for learning to use the algorithm as did their sighted counterparts. A significant difference was found at baseline between the two conditions, indicating the intuitiveness of the original ecologically inspired mapping. Despite this, participants were able to achieve similar success rates following the training in both conditions. The findings indicate that both intrinsic and learned cues come into play with respect to depth perception. Moreover, they suggest that by employing perceptual learning, novel sensory mappings can be trained in adulthood. Regarding the blind and visually impaired, the results also support the convergence view, which claims that with training, their spatial abilities can converge with those of the sighted. Finally, we discuss how the algorithm can open new avenues for accessibility technologies, virtual reality, and other practical applications.

Reward history guides focal attention in whisker somatosensory cortex.

Prior reward is a potent cue for attentional capture, but the underlying neurobiology is largely unknown. In a novel whisker touch detection task, we show that mice flexibly shift attention between specific whiskers on a trial-by-trial timescale, guided by the recent history of stimulus-reward association. Two-photon calcium imaging and spike recordings revealed a robust neurobiological correlate of attention in the somatosensory cortex (S1), boosting sensory responses to the attended whisker in L2/3 and L5, but not L4. Attentional boosting in L2/3 pyramidal cells was topographically precise and whisker-specific, and shifted receptive fields toward the attended whisker. L2/3 VIP interneurons were broadly activated by whisker stimuli, motion, and arousal but did not carry a whisker-specific attentional signal, and thus did not mediate spatially focused tactile attention. Together, these findings establish a new model of focal attention in the mouse whisker tactile system, showing that the history of stimuli and rewards in the recent past can dynamically engage local modulation in cortical sensory maps to guide flexible shifts in ongoing behavior.

Using Wearable Sensors to Study Musical Experience: A Systematic Review.

Over the last few decades, a growing number of studies have used wearable technologies, such as inertial and pressure sensors, to investigate various domains of music experience, from performance to education. In this paper, we systematically review this body of literature using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) method. The initial search yielded a total of 359 records. After removing duplicates and screening for content, 23 records were deemed fully eligible for further analysis. Studies were grouped into four categories based on their main objective, namely performance-oriented systems, measuring physiological parameters, gesture recognition, and sensory mapping. The reviewed literature demonstrated the various ways in which wearable systems impact musical contexts, from the design of multi-sensory instruments to systems monitoring key learning parameters. Limitations also emerged, mostly related to the technology's comfort and usability, and directions for future research in wearables and music are outlined.

Mapping Tokyo Olympics 3.0: archaeologies of the future

ABSTRACT Mapping Tokyo Olympics 3.0 is a collaborative sensory archive of demolition and displacement surrounding the three Tokyo Olympics. Understanding the Olympics as a cyclical `practice of subtraction,' where the city is not only rebuilt but unbuilt, we uncover the intertwined layers of the urban development history of these Games and the imperial (1940), high-growth (1964) and post-growth (2020/2021) periods in which they have occurred. Cancelled due to World War II, the first Tokyo Olympics were a phantom event; the second was held in the wake of massive protests against the US-Japan Security Treaty; and the third was postponed and hobbled by the global pandemic amid lingering fears caused by the Fukushima nuclear disaster. Each iteration of the Games has imposed physical effects on the urban landscape of Tokyo with the displacement of vulnerable and precarious persons as a consequence. Mapping the politics of demolition and displacement with the tools of hybrid spatial-sensory ethnography and using intermedial approaches, Mapping Tokyo Olympics 3.0 is a sensory archive of the lived experience of those displacements. Incorporating local knowledge and collaborative research-creation methodologies, we uncover layers of time, history and materiality to embrace contingencies and envision social futures. The sensory mapping archive becomes an archaeology of the future.

Time Makes Space: Emergence of Place Fields in Networks Encoding Temporally Continuous Sensory Experiences.

The vertebrate hippocampus is believed to use recurrent connectivity in area CA3 to support episodic memory recall from partial cues. This brain area also contains place cells, whose location-selective firing fields implement maps supporting spatial memory. Here we show that place cells emerge in networks trained to remember temporally continuous sensory episodes. We model CA3 as a recurrent autoencoder that recalls and reconstructs sensory experiences from noisy and partially occluded observations by agents traversing simulated arenas. The agents move in realistic trajectories modeled from rodents and environments are modeled as continuously varying, high-dimensional, sensory experience maps (spatially smoothed Gaussian random fields). Training our autoencoder to accurately pattern-complete and reconstruct sensory experiences with a constraint on total activity causes spatially localized firing fields, i.e., place cells, to emerge in the encoding layer. The emergent place fields reproduce key aspects of hippocampal phenomenology: a) remapping (maintenance of and reversion to distinct learned maps in different environments), implemented via repositioning of experience manifolds in the network's hidden layer, b) orthogonality of spatial representations in different arenas, c) robust place field emergence in differently shaped rooms, with single units showing multiple place fields in large or complex spaces, and d) slow representational drift of place fields. We argue that these results arise because continuous traversal of space makes sensory experience temporally continuous. We make testable predictions: a) rapidly changing sensory context will disrupt place fields, b) place fields will form even if recurrent connections are blocked, but reversion to previously learned representations upon remapping will be abolished, c) the dimension of temporally smooth experience sets the dimensionality of place fields, including during virtual navigation of abstract spaces.

Kinetic features dictate sensorimotor alignment in the superior colliculus

The execution of goal-oriented behaviours requires a spatially coherent alignment between sensory and motor maps. The current model for sensorimotor transformation in the superior colliculus relies on the topographic mapping of static spatial receptive fields onto movement endpoints1–6. Here, to experimentally assess the validity of this canonical static model of alignment, we dissected the visuo-motor network in the superior colliculus and performed in vivo intracellular and extracellular recordings across layers, in restrained and unrestrained conditions, to assess both the motor and the visual tuning of individual motor and premotor neurons. We found that collicular motor units have poorly defined visual static spatial receptive fields and respond instead to kinetic visual features, revealing the existence of a direct alignment in vectorial space between sensory and movement vectors, rather than between spatial receptive fields and movement endpoints as canonically hypothesized. We show that a neural network built according to these kinetic alignment principles is ideally placed to sustain ethological behaviours such as the rapid interception of moving and static targets. These findings reveal a novel dimension of the sensorimotor alignment process. By extending the alignment from the static to the kinetic domain this work provides a novel conceptual framework for understanding the nature of sensorimotor convergence and its relevance in guiding goal-directed behaviours.

(110) THE SURGICAL ANATOMY OF CLITORAL INNERVATION: A REVIEW OF THE CURRENT MEDICAL LITERATURE

Abstract Introduction The clitoris is a crucial structure for sexual arousal and orgasm in people with gynecological anatomy. Despite its functional importance, the innervation of the clitoris has historically been understudied. The innervation of the clitoris includes somatic afferents of the dorsal nerve of the clitoris, a branch of the pudendal nerve and sacral plexus, and autonomic afferents of the cavernous nerve, a branch of the inferior hypogastric plexus. Although we have identified these structures, there remains a paucity of research on surgical techniques to avoid clitoral innervation during pelvic surgery, despite the importance of these nerves in gynecological sexual function. Objective This paper aims to summarize the current literature on clitoral innervation with special attention paid to the anatomical locations of nervous structures within the pelvis to inform future pelvic surgeons and reduce sexual side effects related to clitoral nerve damage. Methods We performed a PubMed search from inception through June 14, 2023 utilizing the Medical Subject Headings (MeSH) search terms “(clitor*)) AND (innerv* OR nerv*) AND (surg*)” and imported this search into Covidence software. Included in the literature search were observational studies, clinical trials, review articles, correspondence, and communications, and only articles in English were included. Results An initial abstract screen of 200 articles resulted in 87 articles that were fully screened and 53 articles that were utilized as within the scope of this paper. 45 papers discussed the dorsal nerve of the clitoris, while 15 papers explored autonomic afferents via the cavernous nerve. The anatomical location of the dorsal nerve of the clitoris has been tracked in 29 papers, most of which utilize cadaver dissection, with at least six anatomic variations identified. The cavernous nerve’s exact location, however, has not been traced as extensively as has the location of the dorsal nerve of the clitoris, perhaps due to its smaller diameter and shorter length. Additional innervation to the clitoris was proposed in 12 studies as well. Many studies suggested that commonly performed procedures, including midurethral sling placement for stress urinary incontinence, labiaplasty, clitoral hood reduction, clitoroplasty, and urogenital sinus repair may interfere with clitoral innervation if not otherwise modified. Two studies discussed sensory mapping techniques prior to pelvic surgery to account for anatomic variation in clitoral innervation. Conclusions The clitoris is a vastly innervated structure with both somatic and autonomic afferents whose locations and anatomic variations should be considered when performing pelvic surgery. Failure to consider not only the dorsal nerve of the clitoris but the cavernous nerve as well may have consequences that negatively impact clitoral sensitivity, engorgement and erection, orgasmic ability, and overall sexual function.

Modeling the Emergence of Circuit Organization and Function during Development.

Developing neural circuits show unique patterns of spontaneous activity and structured network connectivity shaped by diverse activity-dependent plasticity mechanisms. Based on extensive experimental work characterizing patterns of spontaneous activity in different brain regions over development, theoretical and computational models have played an important role in delineating the generation and function of individual features of spontaneous activity and their role in the plasticity-driven formation of circuit connectivity. Here, we review recent modeling efforts that explore how the developing cortex and hippocampus generate spontaneous activity, focusing on specific connectivity profiles and the gradual strengthening of inhibition as the key drivers behind the observed developmental changes in spontaneous activity. We then discuss computational models that mechanistically explore how different plasticity mechanisms use this spontaneous activity to instruct the formation and refinement of circuit connectivity, from the formation of single neuron receptive fields to sensory feature maps and recurrent architectures. We end by highlighting several open challenges regarding the functional implications of the discussed circuit changes, wherein models could provide the missing step linking immature developmental and mature adult information processing capabilities.

Shaping the olfactory map: cell type-specific activity patterns guide circuit formation.

The brain constructs spatially organized sensory maps to represent sensory information. The formation of sensory maps has traditionally been thought to depend on synchronous neuronal activity. However, recent evidence from the olfactory system suggests that cell type-specific temporal patterns of spontaneous activity play an instructive role in shaping the olfactory glomerular map. These findings challenge traditional views and highlight the importance of investigating the spatiotemporal dynamics of neural activity to understand the development of complex neural circuits. This review discusses the implications of new findings in the olfactory system and outlines future research directions.

A Novel Technique for Intraoperative Mapping of the Somatosensory Cortex

Intraoperative mapping of the nervous system is used to identify "eloquent" cortical areas. In this technical report, we describe a novel way of mapping the somatosensory cortex so that injury to those critical pathways can be avoided. An 8-year-old female with drug resistant epilepsy presented for resection of a right posterior parietal focal cortical dysplasia. Left median nerve stimulation was used to record somatosensory evoked potentials (SEPs) directly from the somatosensory cortex with a strip electrode. A handheld monopolar electrode was also used to record both the median and tibial SEP. Total intravenous anesthesia with propofol and remifentanil was used. SEP recordings were obtained from a 4-contact strip electrode placed across the central sulcus. A phase reversal was identified and the most likely post central gyrus was noted. With the strip electrode left in place, a monopolar handheld electrode was used to record the median nerve SEPs from different locations on the postcentral gyrus. The tibial nerve was also stimulated to record where the highest amplitude tibial nerve SEP was present. This map was used delineate functionally "eloquent" areas to avoid during surgery. During resection, the median nerve SEP was recorded from the strip electrode continuously. No significant change in the SEP was noted, and the patient awoke without any sensory deficits. Sensory mapping of the cortex is possible with a handheld monopolar electrode. This technique is easy to perform and can help reduce neurological morbidity.

Markers of sensory dynamics in phenols-rich virgin olive oils under optimal storage conditions

Early changes in sensory quality of phenols-rich virgin olive oil (VOO) and their relationship with the chemical changes are less studied in the literature. Therefore, the objective of this study was to propose a predictive model of dynamics of sensory changes based on specific chemical markers. The evolution of the sensory quality of phenol-rich VOOs from Tuscan cultivars stored under optimal storage conditions (i.e., absence of light, no O2 exposure, low temperature) was investigated using a multi-step methodological approach combining sensory (official sensory analysis (so-called Panel Test), Descriptive Analysis and Temporal Dominance of Sensation) and chemical measurements. The sensory map from descriptive data was related to the phenolic and volatile profiles, measured using HPLC-DAD and HS-SPME-GC–MS, respectively. A predictive model of the sensory changes over storage based on chemical compounds was developed. Results showed that very early changes involving phenolic and volatile compounds profiles occur in VOOs stored under optimal storage conditions, which turn in changes in sensory properties evaluated by the official panel test, the descriptive analysis and the temporal dominance of sensation. Furthermore, a chemical marker of sensory dynamics of oils during storage was identified as the ratio between two groups of secoiridoids. The proposed model, supported by the mentioned chemical marker, has the potential of improving the control of sensory changes in phenols-rich virgin olive oils during storage in optimal conditions.

Pengalaman Sense of Smell pada Arsitektur Rumah Adat Suku Osing

Title: Sense of Smell Experience on Osing Traditional House Architecture Nusantara architecture results from identical thinking on cultural background and natural conditions that produce physical comfort and atmosphere resulting from the response of human senses, one of which is the sense of smell. The study focuses on the influences or sense of smell responses associated with buildings, such as building materials used, softscape, and hardscape that produce certain scents, especially in Osing Tribe's Indigenous Houses. In line with that, the study identified smells through sensory mapping and the smell intensity influencing the atmosphere by superimposing a Likert scale with a smells wheel from two objects studied, Homestay Bata Merah and Villa SoLong in Banyuwangi. The results of this study found that building elements such as wood, terraces, natural stones, ceramics, paving blocks, and linen are the primary materials that give characteristic aroma, followed by vegetation such as trees that have flowers or sweet-aromatic fruit also dominate, especially in the Homestay Bata Merah. On the other hand, the typical smells are also formed by the influence of geographical conditions and wind movements as the medium of smells material spread, as in Vila SoLong, which has typical ocean smells. The sense of smell experience of traditional house buildings also shapes Nusantara Architecture's identity and improves the comfort of visitors or people active in it.

Optimization of direct cortical stimulation using tibial versus median nerve sensory mapping during midline brain tumor resection: illustrative case.

During brain tumor resection, neurophysiological mapping and monitoring help surgeons locate, characterize, and functionally assess eloquent brain areas in real time. The selection of mapping and monitoring targets has implications for successful surgery. Here, the authors compare direct cortical stimulation (DCS) as suggested by median nerve (MN) with posterior tibial nerve (PTN) cortical sensory mapping (SM) during mesial lesion resection. Recordings from a 6-contact cortical strip served to generate an MN and a PTN sensory map, which indicated the strip was anterior to the central sulcus. Responses exhibited an amplitude gradient with no phase reversal (PR). DCS, elicited through a stimulus probe or contact(s) of the strip, yielded larger responses from the corresponding sensory mapped limb; that is, PTN SM resulted in larger lower limb muscle responses than those suggested by MN SM. SM of the MN and PTN is effective for localizing eloquent cortical areas wherein the PTN is favored in surgery for mesial cortical tumors. The recorded amplitude of the cortical somatosensory evoked potential is a valuable criterion for defining the optimal location for DCS, despite an absent PR. The pathway at risk dictates the specifics of SM, which subsequently defines the optimal location for DCS.

Accessibility and Exhibit Safety: The Importance of Sensory Maps

Museum accessibility, through audio description services, sighted guides, sensory maps/guides/social narratives, and more, is an essential part of exhibit safety and design. In the past decade, more museums recognize the importance of trigger warnings (a trigger being a sensory experience that may cause mental or physical discomfort, overload, or breakdown) for flashing lights, noise content, and movement to ensure visitors with epilepsy, tinnitus (ringing in the ears), PTSD, and mobility devices remain safe. But while more museums are developing resources and programming for neurodiverse individuals, including Autism Spectrum Disorder (ASD), many still do not understand how sensory maps, an inclusive and easy-to-create resource, are critical to visitor safety. A sensory map is an annotated layout of an exhibit, gallery, or entire museum that identifies areas with high and low sensory stimulation and the type of stimulation. Sensory overload/overstimulation can put visitors, staff, and collections at risk; sensory maps alleviate this risk by allowing visitors to self-select in or out of experiences, and in doing so, prioritize their own mental and bodily wellbeing. Highlighting how sensory maps are critical for visitor, staff, and object safety encourages museum boards of directors to allocate funding to create these resources and to seek out more funding for tailored programming and exhibit experiences. I met with accessibility professionals from the Metropolitan Museum of Art, the International Spy Museum, the Houston Museum of Art, and others to share their insights about how to create accessible sensory maps (physical and digital versions) and reach out to disabled communities.

Arts-Based Methods in Migration Research. A Methodological Analysis on Participatory Visual Methods and Their Transformative Potentials and Limits in Studying Human Mobility

In the last decades, the growing use of participatory methodologies and creative methods in migration research has opened innovative ways to collect, analyze, and disseminate data. These approaches encourage experimental, interdisciplinary, and collaborative work through artistic methods to study human mobility and expand the community of inquiry and interpretation, often intervening in contexts of social injustice and exclusion. This article is intended as a reflection on the potentialities and limits of the use of arts-based methods in migration research. The contribution opens with a review of how participatory visual methods have been framed in the field of migration studies. The second part explores an example of a collaborative study that adopted photovoice and sensory mapping to reflect on the concept of “welcoming spaces”. Finally, it analyses arts-based methods as a potential space for social change, focusing on three main dimensions: collective learning, relational aesthetics, and knowledge co-construction.
