title: [Effect of cephalic perimeter and temperature on the latency and amplitude of the P100 component of the visual evoked potential].
abstract: Pattern reversal evoked potentials were recorded from 40 people (20 males and 20 females) in good health. Latency and amplitude of P100 as well as cephalic perimeter and temperature were measured. Both samples did not differ in age. Males had a greater cephalic perimeter (p less than 0.00001) and females had a greater temperature (p less than 0.05). Amplitude of P100 decreased with age. We did not obtain any relation among cephalic perimeter or temperature with P100 latency or amplitude. We conclude that the consideration of these measurements does not increase the sensibility of VEP.
