Cingulate gyrus

The cingulate gyrus is a curved cerebral fold or gyrus in the brain that forms part of the limbic cortex. It can be found on the inner surface of each cerebral hemisphere, wrapping around and covering the C-shaped corpus callosum. Starting beneath the front part of the corpus callosum, it wraps around and extends above the upper surface of the corpus callosum to its back end, ending at the isthmus of the cingulate gyrus. This isthmus connects below to the parahippocampal gyrus in the temporal lobe. The cingulate gyrus is separated from the corpus callosum below by the callosal sulcus and from the superior frontal gyrus and paracentral lobule above by the cingulate sulcus. It is also separated from the precuneus by the subparietal sulcus.
