Fentanyl addiction: the brain pathways behind the opioid crisis

00:45 The neuroscience of fentanyl addiction

Research in mice has shown that fentanyl addiction is the result of two brain circuits working in tandem, rather than a single neural pathway as had been previously thought. One circuit underlies the positive feelings this powerful drug elicits, which the other was responsible for the intense withdrawal when it is taken away. Opioid addiction leads to tens of thousands of deaths each year, and the team hopes that this work will help in the development of drugs that are less addictive.
