The age dependence of the P2 amplitudes of visually evoked cortical responses to checkerboard pattern reversal was examined in 72 healthy individuals of between 10 and 69 years of age. Separate examination of the right and left eye yielded no statistically significant differences in P2 amplitudes. An age dependence of the P2 amplitudes was discovered inasmuch as healthy individuals under 25 years and over 55 are--with high statistical significance--apt to show higher P2 amplitudes than healthy individuals in the remaining life span.
