Dec. 20, 2021 – Researchers used functional magnetic resonance imaging (fMRI) to measure the brain responses of cocaine addicts and patients with HIV while participants played a game that involved purposefully withholding responses to target stimuli. “The challenging thing about the game we asked participants to play isn’t exactly playing it, per se,” said Kathryn Mary Wakim, Ph.D., a recent graduate from the Neuroscience Graduate Program at the University of Rochester and the first author of the study. “What’s really hard is not playing the game. What we wanted to measure was how the brain holds back a response under certain task conditions.”
Difficulty withholding inappropriate responses are thought to be a central issue in addiction. Researchers found that participants diagnosed with both HIV and cocaine dependence had a difficult time holding back behavioral responses while playing the game, changes which were also reflected in brain activity. A companion study also published in Neuropharmacology found similar results while brain activity was measured using electroencephalography (EEG). Brain activity during response withholding in HIV+ participants in recovery from cocaine dependence was different than brain activity in HIV- participants in recovery.
