Document Summary

Incongruent stimulus leads to an attention slip (putting coffee in your cereal: participants were doing these tasks while getting an fmri, when participants made an error, there was very little activation of the ifg, Mfg, and the acc: also had long reaction times, on trials after error they had fast and accurate reaction times. Ifg, mfg, and acc were robustly activated: suggests that those 3 structures together are responsible for orientating attention in order to make decisions, cortical regions mediating attentional control. Inferior frontal gyrus (ifg: responsible for stimulus triggered orientation of attention, middle frontal gyrus (medial frontal gyrus) (mfg, maintains task rules in memory. Ifg must be active for the primary visual cortex to be active. Individuals with an ifg, mfg, or acc lesions have difficulty attending to experiments: you can be talking to them directly and their minds will wander.
