FOREBRAIN Diencephalon , pons, medula oblongata MIDBRAIN HINDBRAIN Mid brain (Pons & medula oblongata) Grey Matter: The outer portion of the cerebrum contain cell bodies of the neurons and being in grayish in color is called the Grey Matter. White Matter: The inner portion of the consists of white matter which mainly contains axons of the neurons BRAIN CENTRE AND ITS LOBES Cerebral cortex:The cerebral cortex is the largest part of the human brain and is divided into four lobes: the frontal, parietal, temporal, and occipital lobes. ❖ Frontal lobe: Located behind the forehead, this lobe is the brain's control center and is involved in problem-solving, planning, impulse control, and more. ❖ Parietal lobe: Located above the occipital lobe and behind the frontal lobe, this lobe integrates sensory information, particularly spatial sense and navigation ❖ Occipital lobe: Located at the back of the brain, this lobe processes visual information from the eyes. ❖ ❖ Temporal lobe: Located in front of the occipital lobes and beneath the parietal and frontal lobes, this lobe plays a role in hearing, touch, smell, and memory formation. ❖
