Inferior temporal cortex

A SPECT imaging study of mescaline showed a hyperfrontal pattern in cerebral blood flow, with greater increases on the right side (Hermie et al. 1992). Increases are also seen in inferior temporal cortex and the hippocampus. Decreases in cerebral blood flow occur in occipital and parietal cortical regions. 

The inferior longitudinal fasciculus follows the ventral stream and involves a pathway conjoining the primary visual cortex with the inferior temporal cortex. It is believed to be involved in object identification by integrating feature analysis with object discrimination. Single cell recordings from area V4 of the extrastriate cortex during covert orientation of attention reveal an in-...

Patients with ALS/PDC also show a moderate loss of choline acetyl transferase activity in the midfrontal and inferior parietal cortex and a severe loss in the superior temporal cortex (Masliah et al., 2001). This deficit is similar to that seen in Alzheimer disease and less severe than in Lewy body disease. Thus, cholinergic deficits in the neocortex may contribute to some of the cognitive alterations in ALS/PDC. 

The temporal cortex is situated inferior to the lateral sulcus and is divided into superior middle and inferior temporal gyri (Figure 3.2). On the inner aspect of the superior temporal cortex are the gyri of Heschl, which is the primary auditory region. The inferior portion of the temporal lobe is involved in vision... 

In 1848, the French neurologist Paul Broca was the first to relate specific body functions to specific regions of the brain. Today, we can relate the insula to disgust the anterior cingulate to decision-making the medial orbital prefrontal cortex to reward-seeking and superior temporal sulcus and inferior frontal cortex to feelings of empathy.

The temporal lobe is the inferior middle portion of the cerebral cortex of both hemispheres. The temporal lobes are involved in the analysis of visual and acoustic information and in memory formation. The hippocampus is part of the inner, medial side of the temporal lobes. 

The medial and caudal portions of the midbody of the CC contain interhemispheric projections from the auditory cortices, posterior cingulate, retrosplenial cortex, and insula, and somatosensory and visual cortices to a lesser extent. It also includes connections from the inferior parietal lobe to the contralateral superior temporal sulcus, cingulate, and parahippocampal gyrus (Pandya and Seltzer, 1986). Several of the regions with interhemispheric projections through the medial and caudal portions of the midbody of the CC are involved in the processing of emotional stimuli and various memory functions—core disturbances frequently observed in children with a history of early trauma.
