The brain uses neurotransmitters (chemical messengers ) to communicate with other parts of itself and with the nervous system.

Explanation:

These neurotransmitters are released and received by neurons. Neurons constantly communicate with each other by way of exchanging neurotransmitters. This communication system is essential to all the brains functions.

It is also important that the neurotransmitter receptors be allowed to rest and deactivate between messages so that they can become ready to receive the next burst of neurotransmitters.
Any problem that interrupts the smooth functioning of this chain of chemical events can negatively impact both the brain and nervous system.

Depression has been linked to problems or imbalances in the brain with regard to the neurotransmitters serotonin, norepinephrine and dopamine.
Serotonin is involved in regulating many important physiological functions including sleep, aggression, eating and mood.
Norepinephrine deficiency is responsible for creating depressed mood.
Dopamine plays an important role in regulating our drive to seek out rewards and ability to obtain a sense of pleasure.
