The age dependence of the P2 latency of visually evoked cortical responses to checkerboard pattern reversal was examined in 60 healthy individuals of between 10 and 69 years of age. Separate examination of the right and left eye yielded no statistically significant difference in P2 latency. A certain age dependence of P2 latency was discovered inasmuch as healthy individuals under 15 years and over 65 are--with high statistically significance--apt to show longer P2 latency than healthy individuals in the remaining life span.
