Expert Solution

Brain is formed by cerebral hemisphere that are separated by longitudinal fissure. Cerebral hemisphere is divided into left and right cerebral hemisphere.
Cerebral cortex is the outside layer of the cerebral hemisphere that is composed of grey matter.
Middle layer of the cerebral hemispheres consist of white matter.Deep gray matter is present Innermost layer of the cerebral hemispheres that is composed of basal ganglia.

Right cerebral hemisphere,
Controls the muscles on the left side and receives sensory input from the left side of the body.

Left cerebral hemisphere,
Controls the muscles on the right side and receives the sensory input from the right side of the body.

LOBES OF BRAIN

1)Frontal lobes is located at the top,front region of each of cerebral hemisphere.
Frontal lobe is associated with movement,intelligence,reasoning,personality,planning,decision making,judgment,awareness of abilities and limitations,organisation and mood.

2)Parietal lobe-Located above occipetal lobe and behind frontal lobe.They are actively involved in
Interpretation of sensory input, understanding of speech and formulating words to express thought and emotion, and interpretation of textures and shape.

3)Occipital lobe lobe located in the back of head above neck
It is involved in integration of eye movements in focusing the eye,correlation of visual images-and conscious perception of vision.

4)Temporal lobe located beneath the Sylvain fissure on both cerebral hemispheres.It is involved in auditory perception and storage of auditory and visual experiences
Temporal lobe contains hippocampus that is important in formation of long term memory.It lies in the medial temporal lobe of brain.
This lobe responsible for speech,behaviour,vision,smell and emotions etc.

5)The fifth lobe ,insula which separates the cerebrum into frontal,parietal, and temporal lobes.
Insula is associated in memory,perception of pain and visceral integration of cardiac responses.
