While the dorsal anterior cingulated cortex mostly forms connections with the hippocampus (papez circuit) and lateral prefrontal cortex, the subgenual cingulated cortex (regional aim of subcaudate tractotomy) forms connections with the amygdala, nucleus accumbens, hypothalamus, orbitofrontal cortex and the visceromotor brain stem regions (14).
The anterior cingulated cortex (ACC) has been linked to monitoring task performance and the modulation of arousal during cognitively demanding tasks.
Increased metabolism incerebellum and decreased metabolism in inferior temporal gyros, unmedicated trD vs normal increased metabolism in Thalamus, Cerebellum and inferior frontal gyrus, decreased metabolism inferior temporal gyrii, medicated trD vs normal increased metabolism in cerebellum and decreased metabolism in anterior cingulated and subgenural cingulated were all discussed in detail.
The neurobiological underpinnings of intelligence have been associated with total brain size, white matter volume, and a sophisticated network of cerebral regions including dorsolateral prefrontal cortex (DLPFC), parietal lobe, anterior cingulated cortex and specific regions in the temporal and occipital lobe (Jung & Haier, 2007).
in "passive mode") is less affected by head motion noise and shows a less robust sensorimotor and supplementary motor activity and a cerebellar activation plus some thalamic, frontal, and cingulated clusters.
In related studies, increased cerebral blood flow in the posterior cingulated gyrus, as measured by 3-dimensional PET, was correlated with the number of crashes in a simulator [9].

In addition, Colcombe and colleagues showed that older adults with higher cardiovascular fitness levels are better at activating attentional resources, including decreased activation of the anterior cingulated cortex.
Papez in 1937 described the set of connections in the limbic system that link the hippocampus, mamillary bodies, thalamus, cingulated, and parahippocampal gyrus [1].

The brain areas showing activation include the top-pillow pathway, where the pathway, anterior cingulated cortex, parietal cortex, and premotor areas are located (Ernst et al., 2004; Fukui et al., 2005).
