Abstract
During listening, acoustic features of sounds are extracted in the auditory system (in the auditory brainstem, thalamus, and auditory cortex). To establish auditory percepts of melodies and rhythms (i.e., to establish auditory “Gestalten” and auditory objects), sound information is buffered and processed in the auditory sensory memory. Musical structure is then processed based on acoustical similarities and rhythmical organization, and according to (implicit) knowledge about musical regularities underlying scales, melodic and harmonic progressions, etc. These structures are based on both local and (hierarchically organized) nonlocal dependencies. In addition, music can evoke representations of meaningful concepts, and elicit emotions. This chapter reviews neural correlates of these processes, with regard to both brain-electric responses to sounds, and the neuroanatomical architecture of music perception.
Highlights
The human brain is, by far, the most advanced and complex biological system we know
According to our model, the emotional system has control over the activation and dynamics of attention, which regulates and prioritizes the access of stimuli information to advanced cognitive systems and these, in turn, are able to operate over different functional elements the emotional system utilizes to assess the necessity of displaying an emotion
- Endogenous, which can be of two types: o Physiological, such us the information received through the sensors located inside the body, like those present in the muscles and viscera. o Neural, information that is already represented within different neural systems, or that can be internally generated in the absence of additional sensory information, and which can be cognitively processed and reprocessed through different networks to give place to new internal representations (Baron, 2012; Kohn, Paulus, & Korde, 2011; Mahon & Caramazza, 2009; Martin, 2007; Middleton, Rawson, & Wisniewski, 2011; Patterson et al, 2007)
Summary
In the first two sections we have presented the evolutionary reasoning leading to our model and the functional structure that emerges from this reasoning. We analyze the dynamic model, which describes the way the various parts of the functional structure interact to generate the sensory, emotional, perceptual, cognitive and behavioral phenomena
