LIVE Techno – According to the results of the latest research conducted by scientists, kaddiction to drug addicts heroin And cocaine This is because different parts of the brain get worse communicating with each other.
Launched by the Independent website on Sunday, October 9, 2022, the brains of drug addicts contain less white matter than people who do not use Class A substances. White matter connects everything in the brain together and helps transmit signals.
Researchers previously found less white matter in addicted animals drugs in the lab, but the new study is the first to show the brains of human drug addicts.
Academics in the United States are studying the relationship between the prefrontal cortex, the part of the brain that allows us to carry out daily activities and affects our personality, and habenula, a region that plays an important role in our understanding of risk and of the reward.
Habenula has been found to be an addictive factor in animals. Signals from the prefrontal cortex to the harenula are altered in cocaine-dependent rodents, suggesting that it plays a role in withdrawal and addiction.
The team says this path is not yet well understood in humans. For the study, the researchers used MRI scans to study prefrontal-abenular cortex pathways in heroin and cocaine addicts for humans and a control group of healthy people.
