In line with their previous work, researchers from the Icahn School of Medicine at Mount Sinai showed that individuals with heroin use disorder have lower activity in the anterior and dorsolateral PFC when performing an inhibitory control task compared with healthy controls. Importantly, they revealed that 15 weeks of medication-assisted therapy, which included supplemental group therapy, improves impaired function of the anterior and dorsolateral PFC during an inhibitory control task among the group of participants with heroin use disorder, suggesting a time-dependent recovery of inhibitory control and PFC function in individuals with heroin use disorder after such a treatment intervention.
