Resumo:Fifteen years ago, an influential model proposed that human dorsal anterior cingulate cortex (dACC) detects conflict and induces adaptive control of behaviour. Over the years, support for this model has been mixed, in particular due to divergent findings in human versus nonhuman primates. We here review recent finding that suggest greater commonalities across species. These include equivalent behavioral consequences of conflict and similar neuronal signals in the dACC, but also a common failure of dACC lesions to reliably abolish conflictdriven behavior. We conclude that conflict might be one among many drivers of adjustments in executive control, and that the ACC might be just one component of overlapping distributed systems involved in context-dependent learning and behavioural control.
