“…Replicating results of Fortenbaugh et al (2018), successful withholding of responses (CO -CE) was associated with greater activity in subcortical, cerebellar, visual, and inferior parietal areas and lesser activity in the medial prefrontal cortex, dorsal anterior cingulate cortex, and insula activity in dataset 2 (but not dataset 1; Figure 1). To our knowledge, few studies have contrasted successful and unsuccessful inhibition directly, but one study which examined these conditions separately found increased cuneus, caudate and inferior frontal activity for successful stopping, and increasing anterior cingulate and insula activity with unsuccessful stopping (Chevrier, Noseworth & Schachar, 2007), both of which have previously been associated with error monitoring and adjustments of control (Ramautar, et al, 2006, Shenhav, Cohen, & Botvinick, 2016, Dali et al, 2023. Our CO -CE contrast then likely captures regions contributing to appropriate motor execution or withholding (subcortical, cerebellar, and inferior parietal areas) during successful inhibition, and error processing and control adjustments (medial PFC, dACC, insula) following unsuccessful inhibition.…”
