The human brain
|
Network of neurons
|
The biologic basis of Clinical
Depression originates in the brain. Your brain is made up of a complex
network of nerve cells, called neurons and of brain chemicals, called
neurotransmitters.
|
|
Two neurons
|
Neurotransmitters transmit messages
from one neuron to another. Two of these neurotransmitters, norepinephrine
and serotonin, are not produced in sufficient quantities in a depressed
person’s brain. Because of this lack, too few messages get transmitted
between neurons and the symptomsof
depression occur. In Clinical depression the chemicals in the brain are
out-of-balance.
