It can be divided into two parts, the left and right cerebral hemispheres, which are connected by the corpus callosum, a structure formed by a thick bundle of nerve fibers.

The brain is organized so that forebrain meditates cognitive functions, the brain stem is responsible for regulatory functions such as eating and sleeping, and the spinal cord is responsible for communicating with the motor system.
