Abstract

First, Brodmann areas 27, 28, 36 and 37, were anatomically defined in the beginning of this review. These areas exist in the parahippocampal or fusiform gyrus of the ventral temporal lobe in humans. Subsequently, the current understanding of their functions was summarized on the basis of recent findings mainly through human functional neuroimaging studies and animal studies. Rodent studies have shown the existence of neuronal activities for representing space, such as those involving head-direction cells or grid cells, in areas 27 (the parasubicular cortex) and 28 (the ventral entorhinal cortex). Recent human neuroimaging studies have provided support for the idea that grid cells may also exist in the human entorhinal cortex. Many previous animal studies have shown that area 36 (the lateral perirhinal cortex) is crucial for various types of associative learning. Earlier human neuroimaging studies have also indicated that faces, bodies and visual word forms are represented in different regions of area 37 in the posterior fusiform gyrus. Recent neuroimaging studies in humans have shown substantial functional differentiation between face-related regions in areas 37 and 36, which is similar to that seen in macaque monkeys, as shown through their face patches. This implies the crucial involvement of both areas in face processing.
