- Researchers study a specific brain circuit linked to relapse.
- The circuit connects two brain areas involved in motivation.
- The team used an animal model to mimic people.
- Reducing activity in the circuit lowered drug-seeking behavior.
- One method used a light fiber inside the brain.
- Another method used a designer receptor and a drug.
- Both approaches cut heroin-seeking in the model.
- This research may help reduce relapse in people.
Difficult words
- relapse — return to drug use after stopping
