Definition: a long lobe, the lowest of the major subdivisions of the cortical mantle, forming the posterior two thirds of the ventral surface of the cerebral hemisphere, separated from the frontal and parietal lobes above it by the lateral sulcus arbitrarily delineated by an imaginary plane from the occipital lobe with which it is continuous posteriorly. The temporal lobe has a heterogeneous composition: in addition to a large neocortical component consisting of the superior, middle, and inferior temporal gyri and the lateral and medial occipitotemporal gyri, it includes the largely juxtallocortical parahippocampal gyrus with its paleocortical (olfactory) uncus and, beneath the latter, the amygdala.
Synonym(s): lobus temporalisTA, temporal cortex
