• The upper surface of the brain consists of 'grey matter'
known as the cortex (or cortical area) → It deals with
many of the more complex operations, including making
connections with stored information, analyzing input
and controlling sophisticated muscular movements.

• Below it is the sub-cortex of 'white matter', which is
mainly nerve cell fibers → generally responsible for
reflex actions, controlling functions such as breathing
and heart beats.

• The cerebellum at the base of the brain has a delicate
role in coordinating a range of muscular movements
which have become highly automatic.

• The brain divides into two hemispheres,
one on the left (from the perspective of the
owner of the brain) and one on the right.

•The left hemisphere controls movement
and sensation on the right side of the body
while the right hemisphere is linked to the
left side.
