Corpus callosum
As the largest commissure (connection in the brain), the corpus callosum connects the two cerebral hemispheres. It consists of 200-250 million nerve fibers and serves to exchange information.

Corpus callosotomy
A surgical procedure in which the corpus callosum, the bridge between the two hemispheres of the brain, is severed. This interrupts the flow of information between the two hemispheres. Commissurectomy was previously performed mainly for the purpose of controlling epileptic seizures.

Cingulate gyrus
The cingulate gyrus is an important part of the limbic system in the cerebrum. This strip of cortex runs medially in the cerebrum, directly above the corpus callosum. Among other things, it is involved in emotions and memory. Through its connections to limbic and autonomic centers, it can also influence autonomic responses (e.g., heart rate, blood pressure). The anterior (front) region in particular is also associated with attention, motivation, error monitoring, and emotion regulation.
