New Brain Mechanism Involved in Impulsive Cocaine-Seeking in Rats Discovered – Neuroscience News

Summary: Blocking M2Rs muscarinic acetylcholine receptors in the lateral habenula with an experimental drug increased cocaine-seeking behaviors in rat models of impulsive behaviors. Source: NIH Researchers have found that blocking certain acetylcholine receptors in the lateral habenula (LHb), an area of the brain that balances reward and aversion, made it harder to resist seeking cocaine …
