THE CEREBRUM

2.  The cerebrum or forebrain is the largest and
major part of your brain. Of the twelve billion
neurons contained in your brain, about 9
billion are found on the cerebrum, which
located in the upper region of your brain.
Nerve cells make up the gray surface of the
cerebrum.

3.  The surface of your cerebrum is called the
cerebrum cortex. This protective covering
is folded into ridges and depressions
called convolutions. Remember the folds
in your intestinal wall? Convolutions and
these folds both serve the same
function—that is to increase the surface
area. The cerebral cortex of your brain
controls many functions that are related to
intelligence. You reason out, memorize,
and become creative mainly because of
the cerebral cortex.

4.  Two hemispheres comprise your brain
cerebrum. These two halves are joined to
one another by tough nerves fibers or
axons. It is through the axons that
communication between the right and left
hemisphere is possible. Each of the
hemispheres in your cerebrum is divided
into four lobes—the frontal, temporal,
parietal, and occipital lobes.

5. f or e b Func t i ons
i n t a s t e
r a i n a n d s me l l
Temporal Learning and memory
Parietal Touch and sensory input
Occipital Vision, motor output,
speech
Frontal Personality, thought,
speech

6. Role of the Cerebrum
 Many activities are controlled by specific
regions of the cerebrum. The motor areas
control the muscles, particularly those found
in the face, tongue, neck, shoulders, arms,
trunk, and legs.
 The vision center of the occipital lobe
interprets what you see with your eyes. In the
frontal lobe, you develop emotions,
judgment, will power, and self-control. The
things you see, hear, and feel are registered
as impressions in the sensory areas. Your
intellectual capacity is determined by the
ability of the cerebral cortex to register
impressions, the activity of the association
areas, and the memory of past experiences.

7.  Do you know why most of us are right
handed?
It is because messages from the left
hemisphere of our cerebrum cross over
the neurons that control the movements
on the right side of our body and vice
versa. Generally, one hemisphere of your
brain is dominant over the other. In this
case, the left hemisphere is usually
dominant.

8.  Have you met some paralyzed people
who speak with a slur? Did you observe
what side of the body was affected? In
most people, an area in the left
hemisphere controls speech. The left side
of the brain deals with mathematics and
logic and the right side is responsible for
our artistic and musical talents.
