The cerebrum is the biggest part and highly developed region of the brain. It constitutes about two-thirds of the brain mass. It is also known as telencephalon and along with diencephalon, they encompass the two major divisions of forebrain or prosencephalon.

It is involved in remembering, thinking, problem solving, feeling and movement.


It is composed of 3 sub-regions:

-Cerebral cortex or cerebral hemispheres cortices -Basal ganglia or basal nuclei -Limbic system

The thick-layered neural tissue called cerebral cortex covers majority of the brain which is about 1.5mm to 5mm.

The cerebral cortex is portioned into 4 lobes- frontal lobe, temporal lobe, parietal lobe, and occipital lobe.

The frontal lobe is linked with planning, reasoning, parts of speech, emotions, movement, and problem solving.

The temporal lobe is linked with auditory stimuli recognition and perception, memory, and speech.

The parietal lobe is linked with recognition, orientation, stimuli perception and movement.

The occipital lobe is linked with visual processing.

A deep crease divided the cerebrum into two halves called the left and right hemispheres. The left and right regions are similar in shape. Though some areas have lateralization especially areas involved in language, many cortical areas are duplicated on each side. They may differ in function such as the left hemisphere is connected to logic abilities and controls the body’s movement on the right side while the right hemisphere is on creativity and controls the body’s left side movement.

And a bundle of axons called corpus callosum connects the two halves.


The cerebrum is at the uppermost region of the brain. It is the anterior portion of the forebrain and superior to pons, medulla oblongata and cerebellum.


The cerebrum is associated in varied body functions including:

-Thinking and Perceiving

-Determining Intelligence

-Producing and Understanding Language

-Planning and Organizing

-Interpreting Sensory Signals

-Controlling Motor Function

-Determining Personality
