How does the hippocampal formation mediate memory for stimuli processed by the magnocellular and parvocellular visual pathways? Evidence from the comparison of schizophrenia and amnestic mild cognitive impairment (aMCI)

► Patients with schizophrenia show deficits on paired associates learning. ► This deficit is pronounced for stimuli assessing the magnocellular visual pathway. ► In amnestic mild cognitive impairment, learning does not depend on stimuli. ► In schizophrenia, the magnocellular task correlates with right hippocampal volume.
