Scientists identify new brain mechanism involved in impulsive cocaine-seeking in rats

Tue, 2022-06-28 11:39
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 in a rat model of impulsive behavior. These findings identify a new role for these receptors that may represent a future target for the development of treatments for cocaine use disorder. There are currently no approved medications to treat cocaine use disorder.

No peers, no beers: Research shows youth substance use declined during the COVID-19 pandemic

Cannabis products demonstrate short-term reduction in chronic pain, little else, review finds

Evidence behind the effectiveness of cannabis-related products to treat chronic pain is surprisingly thin, according to a new systematic evidence review. Voters in a number of states have legalized medical and recreational marijuana; however, the researchers found many of the products now available at U.S. dispensaries have not been well studied.

Molecular 'connector' helps cocaine latch on to brain cells, even when drug is in low doses

Thu, 2022-06-02 07:51
Scientists have long known that cocaine works by latching on to molecular connectors on the surface of brain cells, allowing dopamine, a chemical that promotes feelings of pleasure and reward, to accumulate in the space between brain cells. Now scientists say they have found a molecular connector, known as the BASP1 receptor, that binds cocaine, even when the drug is present in very low doses.

Novel sensors enable precise measurement of dopamine

Fri, 2022-05-27 10:14
Dopamine is an important signalling molecule for nerve cells. Its concentration could not be precisely determined with both high spatial or temporal resolution until now. A new method has now made this possible: A research team used modified carbon nanotubes that glow brighter in the presence of the messenger substance dopamine. These sensors visualize the release of dopamine from nerve cells with unprecedented resolution.

Opioid use disorder: Medication that lowers risk of overdose underused

Tue, 2022-05-10 10:24
Researchers found that less than half of Americans who received treatment for opioid use disorder over a five-year period were offered a potentially lifesaving medication. The numbers were even lower for those with what's known as polysubstance use disorder -- when opioid users also misuse other substances.

Brain circuit responsible for cocaine withdrawal-induced anxiety and relapse-related behavior

Tue, 2022-05-03 17:02
New research finds that drug withdrawal-induced anxiety and reinstatement of drug seeking behaviors are controlled by a single pathway in the brain and centered around dopamine cells.
