The process of switching between tasks is cognitively taxing, and gives rise to a task switching cost (TSC), an increase in reaction time immediately after switching [1]. While robust in humans, the presence of TSC in other animals is debated, being absent from some species entirely, thus necessitating study in humans [2,3]. The neurophysiological basis of TSC is also debated, with two competing explanations involving reconfiguration of medial frontal cortical (MFC) activity for the current task, or lack of inhibition of the previous task. To disambiguate between these explanations, we conduct
