What part of the brain is the cingulate gyrus?
The Cingulate gyrus lies on the medial aspect of the cerebral hemisphere. It forms a major part of the limbic system which has functions in emotion and behaviour.

Cingulate cortex in the three limbic subsystems Broca's (1878) definition of the limbic lobe referred to its being located at the edge of the cerebral cortex, and Papez (1937) and MacLean (1990) welded a series of medial surface structures into what we now know as the limbic system. The last four decades of research have provided a wealth of deta …
What is the limbic system?
The limbic system is a collection of structures involved in processing emotion and memory, including the hippocampus, the amygdala, and the hypothalamus. The limbic system is located within the cerebrum of the brain, immediately below the temporal lobes, and buried under the cerebral cortex (the cortex is the outermost part of the brain).
How does the anterior cingulate gyrus affect bonding?
Not coincidentally, the anterior cingulate gyrus also has connections with the amygdala, the brain structure which processes emotions and relates them to particular events, thus also facilitating the bonding process.

Where is the cingulate gyrus located?
The cingulate gyrus commences below the rostrum of the corpus callosum. Here, it spans the width of the lamina terminalis to the anterior commissure, curves around in front of the genu of the corpus callosum, travels along the superior surface of the body, and terminates at a narrow isthmus behind the splenium. The isthmus of the cingulate gyrus is continuous inferiorly with the parahippocampal gyrus in the temporal lobe of the human brain.

The inferior limit of the cingulate gyrus is defined at the callosal sulcus, and superiorly, it is bounded by the inferior bank of the cingulate sulcus. In both humans and nonhuman primates, the cingulate cortex consists of the cingulate gyrus and the cortical matter in the overlaying cingulate sulcus.

In 1909, Brodmann defined a pre-cingulate region (areas 25, 24 and 32; anterior cingulate cortex) and a post-cingulate region (areas 23 and 31; posterior cingulate cortex) with the clearest distinction between the two being their cortical layer IV neurons. In the anterior segments of the cingulate surface, the cortex is very thin, and lacks a granular layer IV. Conversely, the posterior cingulate cortex is either dysgranular or has a pronounced and distinct accumulation of granular cells.
