| Further Dissociating the Processes Involved Recognition Memory fMRI Study Richard Henson Michael Hornberger and Michael Rugg Abstract Based event related potential study Rugg Dissociation the neural correlates implicit and explicit memory Nature attempted isolate the hemodynamic correlates recollection familiarity and implicit memory within single verbal recognition memory task using event related fMRI Words were randomly cued for either deep shallow processing and then intermixed with new words for yes recognition The number studied words was such that whereas most were recognized hits appreciable number shallow studied words were not misses Comparison deep hits versus shallow hits test revealed activations regions including the left inferior parietal gyrus Comparison shallow hits versus shallow misses revealed activations regions including the bilateral intraparietal sulci the left posterior middle frontal gyrus and the left frontopolar cortex Comparison hits versus correct rejections revealed relative deactivation anterior left medial temporal region most likely the perirhinal cortex Comparison shallow misses versus correct rejections did not reveal response decreases any regions expected the basis previous imaging studies priming Given these and previous data associate the left inferior parietal activation with recollection the left anterior medial temporal deactivation with familiarity and the intraparietal and prefrontal responses with target detection The absence diffe | |||||||||||
