In the cerebrum, there are fifty hundred to one hundred thousand neurons, the
telegram of information is sent from place to place like a telegram. The cerebrum is
divided in to two hemispheres, the right and left hemispheres. The dividing point is a
deep grove called the longitudal cerebral fissure. The different sides of the cerebrum do
different things for the opposite sides of the body. The right side of the cerebrum
controls things such as imagination and 3-D forms. The other side of the brain, the left
side, controls numbering skills, posture, and reasoning. The hemispheres also consist of
many other parts such as the lobes.
Each hemisphere is divided into four sections,
the frontal, parietal, temporal, and the occupial lobes. The hemispheres also consist of a
inner core called the white matter and the cortex, the wrinkly outer layer.
