Nerve cells are information centers: carry messages, electrical impulse travels through cells. Cells release chemicals after impulse into synapse. Reuptake removes chemical and returns it to original cell. Neurotransmitters: chemicals that transmit information from cell to cell. Information is transmitted to other cells using fibres and electrical charges. Receptors: recognize neurotransmitter molecules, when activated, lead to change in electric activity of neurons. Psychoactive drugs: enter the brain and effect which transmitters/chemicals get released into synapse, chronic use can affect process and structure of the brain. Dopamine: feelings of pleasure, associated with thought processes and coordination and movement, many drugs have first effect on dopamine.
