“Mair, Warrington, and Weiskrantz (1979) suggested that the mammillary body lesions (present in each of these patients) may account for the memory loss. Lesions restricted to the mammillary bodies have not been associated with deficits on DNMS^([delayed non-match to sample]) tasks in monkeys (Aggleton & Mishkin, 1985); however, deficits have been found on spatial memory tasks in monkeys (Parker & Gaffan, 1997) and in rats (Sziklas & Petrides, 1998).”
