When a nerve signals reaches the end of one cell, it must pass over a gap to reach the other one. The nerve causes a release of chemicals called neurotransmitters. Partly responsible for depression may be the improper delay of signals that occur.
Although the underlying factors of depression are not well understood, multiple clues suggested tell us of various systems in the brain that may cause depression or be affected by it. Excessive sleep plays a major role in encouraging depression. With this being said, researchers believe that the brain stem is the underlying cause of depression. In congruency with the abnormalities in the cerebral cortex, which controls thinking, many have come to conclude that the probability of negative thoughts and the inability to concentrate can be characteristic of depression.
