Abstract
PREVIOUS attempts to correlate electrophysiological variables with behavioural indices of intelligence have been inconclusive1. Recent findings suggest that the average evoked potential (AEP) recorded from the human scalp may reflect the neural correlates of higher mental activity or information processing by the brain2. The speed of this process, measured by the latency of sequential AEP components, could be the biological substrate of individual differences in behavioural intelligence. AEP latency data from cretinized rats3, hypothyroid patients4, aribo-flavinotic children5 and humans with differential intelligence6 provide preliminary support for this hypothesis.
