The corpus collasum.
The cerebral hemispheres are connected by the corpus callosum.
You have the beautiful partition called as falx cerebri, which separates the cerebral hemisphere incompletely. This partition is made from the folding of the inner layer of the Dura mater. Dura mater is the outer covering of the meninges.
Commissural fibers. These fibers connect the hemispheres of the brain including the cerebral portion.
There is one major fissure that divides the cerebral hemispheres, called the longitudinal fissure. It separates the left and right hemispheres of the brain.
Longitudinal Fissure the longitudinal fissure
Association fibers connect different portions of cerebral hemisphere allowing cerebral cortex to function as a integrated whole whereas projection fibers connect cerebral hemispheres to other portions of brain n spinal cord
The transverse fissure.
The cerebral hemispheres account for about 83% of total brain mass.
Awareness is regulated by cortical areas within the cerebral hemispheres, the outermost layer of the brain that separates humans from other animals by allowing for greater intellectual functioning.
Cerebral hemispheres of the brain
You actually have two as the brain is divided into two hemispheres each covered by a cortex and connected by nerve fibers in the corpus callosum.
