Topic: area 8Av

Research has implicated frontal granular area 8Av, in the caudal middle frontal gyrus in the human brain and in the periarcuate region in macaque monkeys, in selectively allocating attention to a visual target from among distractors based on previously learned rules; that is, if stimulus A is presented, select response X, but if stimulus B is presented, select response Y. Recent functional neuroimaging in healthy human participants has only examined this cognitive ability to guide decisions based on internalized rules when the behavioural output has a spatial component. The aim of the present
