| Isthmus of cingulate gyrus(Brodmann area 29) | |
| Latin: | isthmus gyri cinguli |
The cingulate gyrus commences below the rostrum of the corpus callosum, curves around in front of the genu, extends along the upper surface of the body, and finally turns downward behind the splenium, where it is connected by a narrow isthmus with the parahippocampal gyrus.
