Brain and the music: a window to the comprehension of the interactive brain functioning

ABSTRACT

Here we review the most important psychological aspects of music, its neural substrates, its universality and likely biological origins and, finally, how the study of neurocognition and emotions of music can provide one of the most important windows to the comprehension of the higher brain functioning and human mind. We begin with the main aspects of the theory of modularity, its behavioral and neuropsychological evidences. Then, we discuss basic psychology and neuropsychology of music and show how music and language are cognitively and neurofunctionally related. Subsequently we briefly present the evidences against the view of a high degree of specification and encapsulation of the putative language module, and how the ethnomusicological, pscychological and neurocognitive studies on music help to shed light on the issues of modularity and evolution, and appear to give further support for a cross-modal, interactive view of neurocognitive processes. Finally, we will argue that the notion of large modules do not adequately describe the organization of complex brain functions such as language, math or music, and propose a less radical view of modularity, in which the modular systems are specified not at the level of culturally determined cognitive domains but more at the level of perceptual and sensorimotor representations.
