However , when an electrical impulse is received by the axon, the impulse becomes chemical in nature known as neurotransmitters. The main function of these neurotransmitters is to deliver the message from one neuron to another. When a dendrite r eceives the message, the chemical impulse is converted again into an electrical impulse which repeats the whole process again.Of the 30 or so neurotransmitters that need been identified, researchers have discovered associations between clinical depression and the function of three primary ones serotonin, norepinephrine, and dopamine.
