It is a narrow band located in the anterior cingulate gyrus adjacent to the supracallosal gyrus in the depth of the callosal sulcus, near the genu of the corpus callosum.

Neuro-pathological and structural neuroimaging studies in patients with major depressive disorder have indicated abnormalities within the subgenual anterior cingulate gyrus and volume reductions within the hippocampus, ventral striatal regions and amygdala.

In one study using fMRI and SCR, researchers found novel visual stimuli associated with SCR responses typical of an OR also corresponded to activation in the hippocampus, anterior cingulate gyrus, and ventromedial prefrontal cortex.

AHS can involve damage to the anterior cingulate gyrus, the medial prefrontal cortex and the anterior corpus callosum when a patient has frontal AHS . The other type of AHS, callosal AHS, is due to an anterior callosal lesion and affects dominant hemisphere control.
