Objective: To investigate whether differences in visual evoked potential (VEP) latencies in a large sample of healthy subjects are influenced by different head size or sex or both. Methods: Black-and-white pattern-reversal checkerboard VEPs at a frequency of 2 c/deg. were recorded in a group of 54 normal subjects of both sexes (age 30.15±9.12 years). P100 latency was measured in all subjects and the data were analyzed in the whole sample and in a selected subgroup of subjects of both sexes with comparable head size. Results: In the study group overall, the P100 latency was slightly shorter in females than males and this small difference reached only weak statistical significance (P
