Figure 1

Visual schematic of the response inhibition (RI) task with arrows indicating possible outcomes. The RI task requires subjects to withhold responding until the correct phase. Responses during the correct phase result in a sucrose pellet reward and reinstate the inter-trial interval (ITI). Responses during the premature phase restore the ITI with no reward. Failure to respond during the correct phase results in an omission and reinstates the ITI.
