title: Sex differences in the human group mean SEP.
abstract: With 200 SEPs of normal human subjects, the sex differences in the waveform of the Group Mean SEP were established eliminating those attributable to the peripheral factors, the statures and the nutritional conditions represented by Rohrer's index. The differences in baseline amplitude of the Group Mean SEP between sexes, in the sections between 25--110 msec and behind 400 msec in latency, were verified removing those between the tallers and the shorters and those between with high and with low values of Rohrer's index, not attributable to these peripheral factors and might be the central origin. The differences in the Scaled Group Mean SEP were also verified similarly, being more a significant indication of the sex difference itself than those in the Group Mean SEP.
