A neurotransmitter is a signal substance that sends the nerve signal through the junctions between 2 afferent neuron.

Serotonin and noradrenalin cause afferent neuron to send out impulses along to other afferent neuron, and thus increase the activity in the brain. Shortage of these compounds triggers sluggishness in parts of the brain, and that again causes the depressive symptoms.
