The major pathway of communication between the right and left hemisphere is the corpus callosum.
- The cerebrum is the recognizable gray covering of the human brain, appearing to comprise the majority of its mass.
- The cerebral cortex is the wrinkly area; the remainder of the anatomy is hidden behind that layer.
- The longitudinal fissure, which is a significant gap between the two sides of the cerebrum, exists.
- It divides the brain into right and left cerebral hemispheres, which are two independent parts.
- The main channel for communication between the two hemispheres of the cerebral cortex is provided by the white matter of the corpus callosum, which is located deep inside the cerebrum.
