Right in the middle of the spinal cord and the rest of the brain is the brain stem. This particular area is associated with functions like breathing and sleep. Breathing or falling asleep seem like things that just occur naturally but the truth is that the brain plays an important role in controlling them.

The region at the back and base of the brain is known as the cerebellum. This region is responsible for balance and general body coordination. An interference with this region may lead to impaired body movements such as walking.
