To reveal neurophysiological prerequisites of musicality, auditory
event-related potentials (ERPs) were recorded from musical and non-musical
subjects, musicality being here defined as the ability to temporally
structure auditory information. Instructed to read a book and to
ignore sounds, subjects were presented with a repetitive sound pattern
with occasional changes in its temporal structure. The mismatch negativity
(MMN) component of ERPs, indexing the cortical preattentive detection
of change in these stimulus patterns, was larger in amplitude in
musical than non-musical subjects. This amplitude enhancement, indicating
more accurate sensory memory function in musical subjects, suggests
that even the cognitive component of musicality, traditionally regarded
as depending on attention-related brain processes, in fact, is based
on neural mechanisms present already at the preattentive level.
