Your brain includes billions of neurons which are specialised cells, allowing your brain to learn, reason, and remember. Through the activity of neurons, the body responds and adjusts to changes in the environment. Every time you feel something - including the effects of a drug - millions of neurons are "firing" messages to and from one another. These messages consist of chemical and electrical impulses.
