Musical training is known to modify cortical organization. Here, we
show that such modifications extend to subcortical sensory structures
and generalize to processing of speech. Musicians had earlier and
larger brainstem responses than nonmusician controls to both speech
and music stimuli presented in auditory and audiovisual conditions,
evident as early as 10 ms after acoustic onset. Phase-locking to
stimulus periodicity, which likely underlies perception of pitch,
was enhanced in musicians and strongly correlated with length of
musical practice. In addition, viewing videos of speech (lip-reading)
and music (instrument being played) enhanced temporal and frequency
encoding in the auditory brainstem, particularly in musicians. These
findings demonstrate practice-related changes in the early sensory
encoding of auditory and audiovisual information.
