Most people will take a pill, receive an injection, or otherwise take some kind of medicine during their lives. But most of us don’t know anything about how these substances actually work. How can various compounds impact the way we physically feel, think, and even behave? Sara Garofalo explains how some drugs can alter the communication between cells in the brain.

In synaptic transmission, several neurotransmitters are released from the sending neuron and some of these are captured by the receiving neuron. Any neurotransmitter that remains is then degraded or reabsorbed into the transmitting neuron. Can you imagine the consequences of an abnormal degradation or reabsorption of neurotransmitters? What happens if neurotransmitters are persistently available in the synaptic space?
