The present study uses cortical auditory evoked potentials (CAEPs) to investigate neuroplasticity by assessing the latency of P1, N1, P2, and N2 as well as the peak-to-peak amplitudes P1–N1, N1–P2, and P2–N2 in two groups of subjects: Carnatic vocal musicians and non-musicians. Material and Methods: Two groups of normal hearing females aged 18 to 25 years. There were 20 Carnatic vocal musicians (Indian classical music of south India) and 20 non-musicians. Pure tones were used as stimuli.Results: Descriptive statistics revealed lower latency and greater peak-to-peak amplitude for all measures in the Carnatic vocal musicians compared to the non-musicians. MANOVA showed that vocalists had significantly better (shorter) N1, P2, and N2 latencies and significantly better (greater) peak-to-peak amplitude of P1–N1.Conclusions:The present study showed some significantly enhanced CAEP parameters in Carnatic vocal musicians compared to non-musicians. This indicates that musical experience has an effect on the central auditory nervous system, and this form of neuroplasticity can be investigated with CAEPs.
