Cingulate gyrus (lat. belt ridge) is a gyrus in the medial part of the brain. It partially wraps around the corpus callosum and is limited above by the cingulate sulcus.
The cortical part of the cingulate gyrus is referred to as cingulate cortex.
The cingulate gyrus receives inputs from the anterior nucleus of the thalamus and the neocortex, as well as from somatosensory areas of the cerebral cortex. It projects to the entorhinal cortex via the cingulum. It functions as an integral part of the limbic system, which is involved with emotion formation and processing, learning, and memory. Also, executive control needed to suppress inappropriate unconscious priming is known to involve the anterior cingulate gyrus.
