AP PSYCHOLOGY

Detailed explanation-1: -The bundles of nerve fibres inside the central nervous system (brain and spinal cord) are called the tracts . Hence, the left and right cerebral hemispheres are connected to each other by a tract of nerve fibres. This tract of nerve fibres which connects the two cerebral hemispheres is called the corpus callosum.

Detailed explanation-2: -The corpus callosum is composed of millions of nerve fibers that connect the two halves of the brain. These fibers traveling together from one cerebral hemisphere to the other form a brain structure easily visible to the beginning student of neuroanatomy.

Detailed explanation-3: -The two hemispheres are connected by a thick band of nerve fibres called the corpus callosum. The brain halves are able to communicate with each other via this ‘bridge’.

Detailed explanation-4: -The cerebrum is divided into the left and right hemispheres by a deep longitudinal fissure; the two hemispheres remain in contact and communication with one another by the corpus callosum.
