summary | Medial prefrontal cortex (mPFC) has been repeatedly and extensively implicated in processing and monitoring behaviour. How exactly this is achieved, however, is currently the subject of lively debate. A recent computational model of the mPFC (Alexander & Brown, 2011) posits that mPFC learns predictions of the probability and timing of outcomes, regardless of their valence, and signals unexpected deviations from these predictions (surprise signals). Here, I will present some evidence that supports this model by investigating the mediofrontal negativity, a component of the event-related brain potential that is commonly assumed to be a reflection of mPFC activity. |
