Memory and Growth in the Superior Temporal Gyri

Abstract

The superior temporal gyri were measured in 33 infants and in 33 adults. In the adults, most right superior temporal gyri were larger. This asymmetry was not found in infants, a difference which suggests greater growth of the right superior temporal gyri in the population from which our sample was taken. The asymmetry may be related to the functional asymmetry found by Penfield: some of his patients reported re-experiencing of past sensory experiences with electrical stimulation of the temporal lobe. This response was more frequently evoked from the right hemisphere. © 1975, Canadian Neurological Sciences Federation. All rights reserved.
