The cingulate gyrus (from Latin gyrus 'turn' and cingulum 'belt' ) or belt turn is a part of the brain and functionally belongs to the limbic system . It is a structure of the telencephalon (endbrain), above the corpus callosum (bar), which connects the medial parts of the hemispheres .
The cingulate gyrus consists of four sections:
- Pars anterior = Brodmann area 24
- Pars posterior = Brodmann area 23
- Area subcallosa = Brodmann area 25
- cingulate motor areas = Brodmann area 32
A long association pathway, the cingulum, runs in the medullary bed of the cingulate gyrus . It ends in the cortex of the subiculum of the hippocampus formation.
Surgical cutting of the cingulate gyrus is called a cingulotomy .
As part of the limbic system, the cingulate gyrus is involved in the development and processing of emotions as well as in learning and memory processes. It seems to play a decisive role in the emotional evaluation of the external environment and its connection with the internal emotional state. Compassion and emotional ties are localized here. In the case of disturbances in the general attitude to life and a negative mood such as depression , changes in neural activity can often be detected here. Skills such as shifting attention, adapting to changes and recognizing options are also located here.
