In this interactive activity from the University of Utah, learn how different kinds of drugs alter the natural state of a mouse's brain. Alcohol, cocaine, ecstasy, heroin, LSD, marijuana, and methamphetamine change the communication pathways between neurons and affect neurotransmission. This activity focuses on the brain's reward pathway and looks at how the molecular mechanisms of these drugs change the normal function of the brain. It is also important to note that drugs have other effects on the body, such as increased or decreased heart rate, respiratory problems, distorted sensory perception, loss of coordination, and altered thought processes.
