TI  - Amplitudes of visually evoked potentials to patterned stimuli: age and sex 
      comparisons.
PG  - 81-5
AB  - Electrophysiological age and sex differences in visual pattern responsivity were 
      investigated. Pattern reversal evoked potentials (PREPs) and visual evoked 
      potentials (VEPs) to patterned and unpatterned flashes were recorded from 20 
      normal subjects in each of 4 groups: young females and males aged 25-35 years and 
      older females and males aged 55-70 years. PREP waves N70-P100 and P100-N150 from 
      the older women were significantly larger than those from subjects in the other 
      groups; mean amplitudes for the young females, young males and older males were 
      not different. A similar effect, unusually large potentials for the older women, 
      was obtained for VEPs, but only for VEPs elicited by patterned flashes and 
      recorded from occipital scalp, i.e., an area overlying visual cortex which is 
      sensitive to lines and edges. Our findings suggest that the visual system of 
      older females is unusually responsive to patterned stimuli.
