In this picture you can clearly have a look at the bottom/inferior surface of the human #brain . • You can clearly appreciate the Cerebrum, cerebellum, brain stem, Optic nerve, Optic chiasm and its many other anatomical parts. •Anatomically these brain parts are marked by visible gross features like the gyri and sulci of the cerebrum and cerebellum. Each part is also divided into subparts or regions for simplified localization of the structures. For example, the brainstem is composed of the midbrain, pons and medulla oblongata, while the cerebrum is divisible into lobes. • Sulci are small grooves, but there are also some large grooves called fissures. Fissures divide the cerebral cortex into lobes, and also divide the cerebrum into the right and left cerebral hemispheres along the sagittal plane, thus partitioning the structure called the corpus callosum into two halves. • Furthermore, the structures seen at this view are specifically referred to as the "Cortex", the most superficial layer of these brain parts, and comprise the largest portion of the brain's gray matter.
