Dopamine is increased in the brain by narcotics and alcohol if there is a decreased level it can cause depression or even schizophrenia. Anxiety is something that affects a lot of people today and this is caused by a decreased level of GABA. The cell body is what has the neurons nucleus. Dendrites branches out and looks like a tree it receives an alert and broadcast them toward the cell body. The axon carries alerts away from the cell body. The synapse is known as the gap between the receiving cell and axon terminals.
