If you do something pleasing, the brain is wired in such a way that you tend replicate the action to receive the same reward. NEURONS Dopamine is the chemical often associated with feelings of pleasure and euphoria Dopamine travels between brain cells, called neurons, and bind to receptors that trigger good feelings. Normally, this dopamine would be reabsorbed back into the neuron by a dopamine transporter. NEURONS Life sustaining activities, such as eating, activate a circuit of specialized nerve cells devoted to producing and regulating pleasure. Dopamine Production Pleasure Receptors DRUGS ALTER THIS PROCESS (C COCAINE Dopamine Transporter Some drugs, like cocaine, alter this process by attaching to dopamine transporter and blocking the reabsorption, allowing dopamine to build up and continually stimulate the receptors. 10 MINUTES Continually Dopamine Production Pleasure Receptors As a result, you might feel really good for about 10 minutes, in the case of cocaine; but, soon after, dopamine levels in the brain plummet, causing extremely low feelings of depression, which is why many users consume larger and more frequent amounts of the drug hoping to reach that first high.
