Africa-Press – Sierra-Leone. The research revealed that a particular area of the brain of lab animals that exhibited compulsive drug use displayed increased activity compared to the non-compulsive lab animals. A team of Chinese researchers has announced a discovery of what may well be a potential insight into the mechanism behind compulsive drug use.
The authors of the new study, which was published in the journal Science Advances this week, taught a number of lab rats to self-administer cocaine before introducing a footshock punishment into the equation, thus making the drug-taking procedure painful for the rodents.
The researchers observed that some 66 percent of the rats, those that were deemed “shock sensitive”, quickly reduced the cocaine self-administration, while the remaining 34 percent, the “shock resistant” ones, continued to indulge themselves despite the discomfort they ended up inflicting upon themselves in the process.
The team noticed that the rats that thus exhibited compulsive drug use, which is “characterized by persistent substance use despite adverse consequences,” displayed an “increased neural activity of the anterior insular cortex (aIC)” compared to the rats that did not adopt a compulsive behavior.
The team expressed hope that their work might help gain further insight into the nature of compulsive drug use and assist in developing therapies for treating drug addiction.
