Addiction has been called a disease of learning. Once addicted, it is very difficult to unlearn the behavior. For drug addiction, the drugs themselves mimic or alter the ability of neurotransmitters to function properly and for synapses to remodel. A number of the materials on this website address this subject.

Podcast on Decision Making
BrainU instructor and UMN neuroscientist David Redish spoke about his recent book, The Mind within the Brain: How We Make Decisions and How those Decisions Go Wrong, with Eric Zimmer of The One You Feed. In this 37-minute interview, they discuss the types of systems involved in making decisions (deliberative, procedural, Pavlovian...). During the last 15 minutes of the podcast with David Redish and Eric Zimmer, the discussion turns to addiction which is essentially a breakdown of the decision-making system.
Cocaine Use Animation from NIDA
Why Do People Lose Control Over Their Cocaine Use? animation 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.
In simplifying these experimental results for public presentation, the video does not explain that the black line is the ratio of the slope of the green line divided by the slope of the red line. The slope represents how fast the D1 (green) and D2 (red) neurons are firing.
The Workings of the Adolescent Brain
Teenagers are wired to learn — but this same wiring also makes them more vulnerable to addiction. Neuroscientist and BrainFacts.org editor Frances Jensen discusses how the biology of the teen brain presents a double-edged sword in this 3-minute video.
