There are three possible ways to define the prefrontal cortex: • as the granular frontal cortex • as the projection zone of the medial dorsal nucleus of the thalamus • as that part of the frontal cortex whose electrical stimulation does not evoke movements NettetThe inferior frontal sulcus merges with the precentral gyrus posteriorly on parasagittal slices ( Fig. 2c) and from this point follows a horizontal course before ending low in the inferior frontal pole. The inferior frontal gyrus, located below the inferior frontal sulcus, corresponds to Broca's area on the left [13 ].
