The brain is divided into three
areas - brainstem, cerebellum and cerebrum:
The brain stem sits at the base of the brain and
connects to the top of your spine. It maintains important body
functions such as breathing, swallowing, digestion, eye movement and
Brain Stem strokes are often fatal, but when they
are not, they affect many of the functions mentioned above.

affects of stroke.
The cerebellum is located at the bottom of the
brain, at the back of your head. It is attached to the back of the
brain stem, and looks like a miniature brain. It helps control some
automatic responses and behaviors, simple movements such as picking up
a small object, and more complicated tasks such as balancing.
A stroke in the cerebellum could cause a lack of
coordination, clumsiness, shaking or other movement
disorders. Click the Cerebellum button to read more about its
functions and the affects of stroke.
Also known as the "thinking brain," the cerebrum
is the main, bulky part of your brain. This is where thinking and
muscle control occurs. The cerebrum is made of two halves or
Usually, one of these hemispheres is slightly more
developed and is called the dominant side. The dominant side is where
written and spoken language is organized. In almost all of us, the left
hemisphere is dominant even if you are right handed.
Because the nervous system is set up in a
cross-over design, the right side of your brain controls the left side
of your body, and vice versa.
Each hemisphere is divided into four sections
called lobes. Click the Cerebrum button to read more about
