Effects of aging on the temporal frequency characteristics determined by pattern visually evoked cortical potentials

Pattern reversal visually evoked cortical potentials were recorded from 70 normal volunteers, aged from 4 to 70 years. Eleven reversal frequencies between 1 and 20 rev/sec were presented. The progressive reduction in the amplitude of the P100 component with age for lower frequency ranges was shown u...

Description
Summary:Pattern reversal visually evoked cortical potentials were recorded from 70 normal volunteers, aged from 4 to 70 years. Eleven reversal frequencies between 1 and 20 rev/sec were presented. The progressive reduction in the amplitude of the P100 component with age for lower frequency ranges was shown up to the age decade of 30-39 years and the temporal tuning curve became a constant pattern after 40 years. However, there was a trend that the maxima of the tuning curve shifted toward lower frequencies with age after 30 years.
