Serotonin and norepinephrine are the main chemicals responsible for depression.
1 Neurotransmitters-The Brain's Chemical Messengers. 2  The messages are typically carried between neurons by chemicals called neurotransmitters. 3  Receptors-The Brain's Chemical Receivers. 4  The neurotransmitter attaches to a specialized site on the receiving neuron called a receptor.ther drugs, such as amphetamine or cocaine, can cause the neurons to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals. This disruption produces a greatly amplified message, ultimately disrupting communication channels.
