THE CEREBRUM (The FOREBRAIN)

The Cerebrum is the biggest area of our BRAIN.. It is concerned with the functions like thinking & memory.. It is divided into two HEMISPHERES.. The Left Cerebrum controls the right part of our body while the Right Cerebrum controls the left part.. Each Cerebral HEMISPHERE is divided into four basic parts // area known as LOBES::-

è FRONTAL LOBE:: Divided into two parts SUPERIOR FRONTAL LOBE & INFERIOR FRONTAL LOBE.. Overall associated with concept,, planning,, reasoning,, organizing & problem solving.. The front is called the SUPERIOR FRONTAL LOBE or PREFRONTAL LOBE,, responsible for cognitive functions like behaviour,, emotions & determination of personality.. The INFERIOR FRONTAL LOBE exists just behind the SUPERIOR FRONTAL LOBE.. Processes like concept, perception & reasoning etc are the responsibility of INFERIOR FRONTAL LOBE.. Nerve cells that produce movement are lying in this area..

è PARIETAL LOBE:: Associated with movement orientation & perception of stimuli.. It contains the primary sensory cortex,, controls sensations like touch.. There is a association area behind sensory cortex that controls fine sensations which judges the texture,, weight,, size // shapes..

è OCCIPITAL LOBE:: Associated with visual processing, processes vital information.. It is responsible for visual reception,, also contains association area that helps in visual recognition of shapes & colours..

è TEMPORAL LOBE:: Associated with perception & recognition of auditory stimuli, memory & speech.. There are two TEMPORAL LOBES one on each HEMISPHERES,, located just above the level of our ears.. They allow a person to tell one smell from another & one sound from another LOBE.. It also helps in sorting information & also responsible for memorizing things.. RIGHT TEMPORAL LOBE is responsible for visual memory,, picture & videos,, faces etc..,, while the LEFT TEMPORAL LOBE is responsible for verbal memory such as names,, words..
