Reports on research showing that the neurons that deliver dopamine to two regions of the brain's mesolimbic reward system respond differently to opioids, an important finding for drug treatment research.
April 2010 Describes an animal study reporting that peer interaction enhances adolescent rats’ drug reward and discusses the impact of these findings to future research on drug reward in social context.
Researchers have shut down laboratory rats’ compulsive cocaine seeking by stimulating an area of the animals’ prefrontal cortex. The finding raises the possibility that stimulating neurons in this brain area may weaken or break cocaine’s grip on the behavior of people who are addicted to the drug.
December 2010 Reports on an evaluation of the Chief Resident Immersion Training (CRIT) program to assess its effectiveness in improving knowledge, confidence, and preparedness to diagnose, manage, and teach about substance abuse.
New studies show that two novel compounds powerfully suppressed animals’ pain responses, while producing little or none of the respiratory depression and liability for misuse and abuse associated with morphine and other typical opioids.
