BRAIN SYMMETRY MIGHT PLAY A ROLE IN DRUG ABUSE AND ADDICTION
- December 30, 2018
Have you ever felt like your brain is working against you? Most likely, at some point in your life, you have experienced a moment where you felt helpless and just plain frustrated, like invisible strings were making you dwell on annoying thoughts. While this might just be part of another rainy, dreary day in February for most of us, a majority of people suffering from drug abuse and addiction continuously feel like their brain has completely taken over, leaving them helpless and alone. However, according to a 2016 study conducted by the National Institute on Drug Abuse (NIDA), this sense of self-contradiction might actually play a huge role in the process of addictive behavior. How is this possible? Let’s take a closer look and see what the scientists discovered.
Testing Brain Laterality
As part of the study, Dr. Harold Gordon (a member of the NIDA Epidemiology Research Bank) drew from evidence proposing that impulsiveness and cravings (two primary factors behind addiction) might be reflected in the activities of the right and left brain hemispheres. Utilizing previously published reports on MRI studies, Dr. Gordon and his team exposed subjects to two different assessments:
- Go/no-go and stop-signal tests: focus on subjects’ impulse resistance (ability to prevent themselves from repeating learned responses that are inappropriate)
- Cue-induced cravings: focus on the strength of cravings in association with imagery related to drug images, texts, and additional triggers
During the test, Gordon also considered the effectiveness of laterality, the differences between peak activation levels among the two brain hemispheres.
So, ultimately, what did Dr. Gordon and his team discover? As part of the first study on impulsivity, participants chiefly exhibited “right laterality,” meaning they chiefly activated neurons in the right hemisphere when they attempted to put a damper on their impulses. On the other hand, craving responses to drug-related criteria were exhibited in “left laterality.” In other words, impulse control mostly took place in the right sides of the patients’ brains, while more neurons were activated in the left side of the brain when the patients fought cravings. Simply put, this inter-hemisphere differentiation results in a lack of impulse control and craving problems that are associated with addiction.
