NIDA Notes has recently released an animation that covers neuron activity as a result of cocaine use. Below is an excerpt taken from NIDA Notes on their animation:
This animation addresses the question: Why do people lose control over their cocaine use? Researchers monitored the activity of two types of neurons in mice: “urge” neurons, which promote feelings of reward and repeating behaviors that have produced rewards, and “control” neurons, which dampen those feelings and inhibit behavior. Cocaine shifted the balance of activity strongly to the “urge” neurons.
