Interaction of Musicianship and Aging: A Comparison of Cortical Auditory Evoked Potentials

Table 3

Mean and standard deviation values for P1-N1-P2 cortical auditory evoked potential latencies and amplitudes elicited by standard harmonic tone ( = 392 Hz) from older and younger musicians and nonmusicians.

	P1		N1		P2
	Latency (ms)	Amplitude (microvolts)	Latency (ms)	Amplitude (microvolts)	Latency (ms)	Amplitude (microvolts)
Older nonmusicians	65 (8)	2.02 (1.1)	104 (10)	−0.02 (0.95)	171 (15)	2.0 (1.4)
Older musicians	61 (8)	2.24 (0.8)	109 (12)	0.27 (1.1)	174 (15)	1.69 (1.0)
Younger musicians	74 (10)	1.84 (0.75)	105 (11)	0.21 (0.88)	147 (10)	2.21 (1.1)
Younger nonmusicians	74 (10)	2.00 (0.76)	103 (11)	0.199 (1.2)	146 (11)	2.43 (0.81)
