Mindfulness and Behavior Change.

Initiating and maintaining behavior change is key to the prevention and treatment of most preventable chronic medical and psychiatric illnesses. The cultivation of mindfulness, involving acceptance and nonjudgment of present-moment experience, often results in transformative health behavior change. Neural systems involved in motivation and learning have an important role to play. A theoretical model of mindfulness that integrates these mechanisms with the cognitive, emotional, and self-related processes commonly described, while applying an integrated model to health behavior change, is needed. This integrative review (1) defines mindfulness and describes the mindfulness-based intervention movement, (2) synthesizes the neuroscience of mindfulness and integrates motivation and learning mechanisms within a mindful self-regulation model for understanding the complex effects of mindfulness on behavior change, and (3) synthesizes current clinical research evaluating the effects of mindfulness-based interventions targeting health behaviors relevant to psychiatric care. The review provides insight into the limitations of current research and proposes potential mechanisms to be tested in future research and targeted in clinical practice to enhance the impact of mindfulness on behavior change.

A Strong Emergence Hypothesis of Conscious Integration and Neural Rewiring

In this paper we discuss the two-system framework, examine its strengths, point out a fundamental weakness concerning the unity of conscious experience, and then propose a new hypothesis that avoids that weakness and other related concerns. According to our strong emergence hypothesis, what emerges are not merely mental properties in specialized, distributed neural areas, but also a new, irreducibly singular entity (i.e., an emergent self) that functions in a recurrent (or top-down) manner to integrate its mental properties and to rewire its brain. We argue that the former function is suggested, in part, by the effects of anesthetics on sensory integration, and that the latter function is suggested by evidence garnered from the neuroscience of mindfulness, constraint-induced movement therapy for stroke, and neuroimaging data surrounding mental illness. We then discuss how our strong emergence hypothesis relates to the description and treatment of neuropsychiatric disorders. Finally, potential objections are addressed.

Partnering to develop resilience in health professionals and faculty through mindfulness-based education

Given the pressures that exist in our health care system, health care professionals often are under significant stress to provide both quality clinical care to patients and quality teaching to their learners. We present an innovative program to develop faculty and health professional skills in reflective practice and resilience, which strengthen participants' ability to act as effective clinicians, educators, role models, and leaders. The basis of the curriculum rests in the neuroscience of mindfulness and its applications. This program was enabled through a unique partnership between acute care hospitals (Hamilton Health Sciences and St Joseph's Healthcare Hamilton), Family Health Teams (McMaster Family Health Team and Hamilton Family Health Team) and the McMaster Faculty of Health Sciences Program for Faculty Development (PFD), with additional funding support in 2013 from the Ontario Ministry of Health and Long Term Care (MOH-LTC). Data from 2013 course participants (validated measurement tools and qualitative feedback) was analyzed to evaluate the effectiveness of this initiative. This poster outlines the journey of this work and a summary of the data gathered to inform further education.

Mindfulness and Fear Extinction: A Brief Review of Its Current Neuropsychological Literature and Possible Implications for Posttraumatic Stress Disorder.

Research in the neuroscience of mindfulness has grown rapidly in recent years. This includes empirical investigations into structural and functional changes in several brain regions-particularly, the hippocampus, the prefrontal cortex, and the amygdala-in association with the practice of mindfulness. Of interest to the current paper is that such brain regions are also implicated in empirical research focusing on fear extinction. While fear extinction has, therefore, been suggested as one of the possible mechanisms to underlie the positive effects of mindfulness, the conceptual links and research implications have lacked specific focus and detailed discussion in the literature. The purpose of this paper is, therefore, two-fold. First, this paper briefly reviews the extant literature on the neuropsychological mechanisms underlying mindfulness-particularly that, which has been found to be similarly implied in fear extinction-and hence, suggests future research directions based on its current state in the literature. Second, this paper explores the implications of this for fear-based psychopathologies, specifically for posttraumatic stress disorder (PTSD). Discussion from this paper suggests the idea of fear extinction as an underlying mechanism of mindfulness to be one that is still preliminary, yet promising; in turn, elucidating the need for further methodologically rigorous study to specifically determine fear extinction as a result of mindfulness, as well as to incorporate neuroimaging techniques in supporting the existing literature that have found preliminary support of mindfulness for PTSD.

The Neuroscience of Mindfulness: How Mindfulness Alters the Brain and Facilitates Emotion Regulation

Here we present a survey of the current state of the neuroscience of mindfulness, integrating it into a theoretical framework of emotion regulation and linking research to clinical practice. Findings from the neuroscience of emotion regulation are reviewed, implicating activation in the anterior cingulate cortex, insular cortex, and prefrontal cortex, and deactivation of the amygdala. We then review the nascent literature on the neuroscience of mindfulness, which suggests that similar areas are involved in mindfulness processing. People high in dispositional mindfulness display greater activity in the prefrontal cortex, anterior cingulate cortex, and insular cortex and lesser activity in the amygdala than those low in dispositional mindfulness when engaging in various emotionally salient tasks. Similarly, practitioners engaging in intentional mindfulness appear to demonstrate both functional and structural differences from controls in this emotion regulation network, which correlate with behavioral differences in areas ranging from attentional abilities to psychological well-being. We theorize how the neurologic correlates of mindfulness might support the psychologically healthy mindfulness skills of present-moment focus and detachment from self-referential processing. Finally, we address the limitations of the state of this emerging field and suggest areas for future research. Notably, we illustrate a confound in the literature—that research designs rarely disambiguate intentional mindfulness practice from a more intrinsic, dispositional, mindfulness—and propose a terminological framework to rectify this confound in the field.

Signal or noise: brain network interactions underlying the experience and training of mindfulness.

A broad set of brain regions has been associated with the experience and training of mindfulness. Many of these regions lie within key intrinsic brain networks, including the executive control, salience, and default networks. In this paper, we review the existing literature on the cognitive neuroscience of mindfulness through the lens of network science. We describe the characteristics of the intrinsic brain networks implicated in mindfulness and summarize the relevant findings pertaining to changes in functional connectivity (FC) within and between these networks. Convergence across these findings suggests that mindfulness may be associated with increased FC between two regions within the default network: the posterior cingulate cortex and the ventromedial prefrontal cortex. Additionally, extensive meditation experience may be associated with increased FC between the insula and the dorsolateral prefrontal cortex. However, little consensus has emerged within the existing literature owing to the diversity of operational definitions of mindfulness, neuroimaging methods, and network characterizations. We describe several challenges to develop a coherent cognitive neuroscience of mindfulness and to provide detailed recommendations for future research.

Neurodharma Self-Help: Personalized Science Communication as Brain Management.

Over the past ten to fifteenyears, medical interventions, therapeutic approaches and scientific studies involving mindfulness meditation have gained traction in areas such as clinical psychology, psychotherapy, and neuroscience. Simultaneously, mindfulness has had a very strong public appeal. This article examines some of the ways in which the medical and scientific meaning of mindfulness is communicated in public and to the public. In particular, it shows how experts in the field of mindfulness neuroscience seek to communicate to the public at large the imperative of brain fitness for the promotion of health, wellbeing and happiness. The study identifies claims being made in popular outlets that, by and large, bypass traditional mass media, such as self-help books, websites and online videos. By treating this material as a form of personalized science communication, this article contributes to the body of literature that understands science communication as a continuum and the boundary between science and popularized science as the outcome of human negotiations. The study finds that processes of personalization help to build bridges between scientific findings and their supposed application,that they infuse science with subjective meaning, and turn expert communication with the public into a moral vocation.

Mindfulness training for adolescents: A neurodevelopmental perspective on investigating modifications in attention and emotion regulation using event-related brain potentials

Mindfulness training is increasingly being introduced in schools, yet studies examining its impact on the developing brain have been scarce. A neurodevelopmental perspective on mindfulness has been advocated as a powerful tool to enhance our understanding of underlying neurocognitive changes that have implications for developmental well-being research and the implementation of mindfulness in education. To stimulate more research in the developmental cognitive neuroscience of mindfulness, this article outlines possible indexes of mindfulness-based change in adolescence, with a focus on event-related brain potential (ERP) markers. We provide methodological recommendations for future studies and offer examples of research paradigms. We also discuss how mindfulness practice could impact on the development of prefrontal brain structures and enhance attention control and emotion regulation skills in adolescents, impacting in turn on their self-regulation and coping skills. We highlight advantages of the ERP methodology in neurodevelopmental research of mindfulness. It is proposed that research using established experimental tasks targeting ERP components such as the contingent negative variability, N200, error-related negativity and error positivity, P300, and late positive potential could elucidate developmentally salient shifts in the neural plasticity of the adolescent brain induced by mindfulness practice.

Tools of the trade: theory and method in mindfulness neuroscience.

Mindfulness neuroscience is an emerging research field that investigates the underlying mechanisms of different mindfulness practices, different stages and different states of practice as well as different effects of practice over the lifespan. Mindfulness neuroscience research integrates theory and methods from eastern contemplative traditions, western psychology and neuroscience, and from neuroimaging techniques, physiological measures and behavioral tests. We here review several key theoretical and methodological challenges in the empirical study of mindfulness neuroscience and provide suggestions for overcoming these challenges.

Special issue on mindfulness neuroscience

Mindfulness neuroscience is a new, interdisciplinary field of mindfulness practice and neuroscientific research; it applies neuroimaging techniques, physiological measures and behavioral tests to explore the underlying mechanisms of different types, stages and states of mindfulness practice over the lifespan. Mindfulness-based meditation (MBM) or mindfulness-based intervention (MBI) has been a hot topic in psychology, neuroscience, health care and education in recent years (Chiesa and Serretti, 2010; Holzel et al., 2011), and publications have been rapidly growing from only 28 in 2001 to 397 papers listed in ISI during 2011. Many studies indicate the positive effects of MBM or MBI and researchers explore the mechanisms (Lutz et al., 2008; Tang and Posner, 2009; Chiesa and Serretti, 2010; Holzel et al., 2011; Tang et al., 2012a). However, the mechanisms of mindfulness practice are still poorly understood.

Searching for Mindfulness in the Brain: A Process-Oriented Approach to Examining the Neural Correlates of Mindfulness

There has been great interest of late in trying to capture the benefits of meditation by scanning meditators’ brains. In this paper, we argue that a successful neuroscience of mindfulness needs to be based on an adequate psychological analysis. We present a definition of mindfulness based on four psychological processes that are relatively well understood, and we show how this model may help organize neuroimaging research and create a bridge to clinical applications. This framework provides an approach to neuroscience research grounded in psychological principles and theory. We propose that this is critical for advancing scientific endeavors such that the knowledge gained helps improve the human condition.
