Abstract
Prospective memory is a memory feature in humans which involves activi ties for remembering to do something in the future. The present study provides functional neuroanatomy of prospective memory for the first t ime. We used positron emission tomography (PET) and found several loca lized brain activations in relation to a prospective memory task requi red to retain and remember a planned action while performing an ongoin g routine activity. Activations were identified in the right dorsolate ral and ventrolateral prefrontal cortices, the left frontal pole and a nterior cingulate gyrus, the left parahippocampal gyrus, and midline m edial frontal lobe. We attributed these activations to several cogniti ve processes involved in prospective memory, such as holding an intent ion toward future behavior, checking target items within presented sti muli, and dividing attention between the planned action and the routin e activity.
