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

Table 4

Mean and standard deviation values for MMN and P3a cortical auditory evoked potential latencies and amplitudes elicited by deviant harmonic tones (HMD 1.5 and HMD 6) from older and younger musicians and nonmusicians.

		MMN		P3a
		Latency (ms)	Amplitude (microvolts)	Latency (ms)	Amplitude (microvolts)
Older nonmusicians	HMD 1.5	298 (15)	−1.1 (1.3)	330 (20)	−0.06 (1.3)
	HMD 6	200 (19)	−1.62 (0.9)	283 (13)	0.81 (1.1)
Older musicians	HMD 1.5	238 (12)	−1.26 (0.5)	314 (18)	−0.18 (0.8)
	HMD 6	172 (15)	−2.6 (1.7)	251 (16)	0.19 (1.5)
Younger nonmusicians	HMD 1.5	219 (18)	−1.90 (1.1)	297 (14)	0.43 (1.5)
	HMD 6	183 (12)	−3.44 (1.4)	265 (16)	1.47 (1.4)
