RECENT investigations of the temporal lobe have increased our knowledge of different aspects of its activity and have necessitated modifications of our conceptions of the functions of such structures as the hippocampus. It has been reported that the hippocampus, traditionally associated with olfaction, does not receive any direct projection from the olfactory bulb, and that fibres of the olfactory tract reach only the most anterior part of the hippocampal gyrus, which is structurally typical prepiriform cortex. No olfactory tract fibres have been traced to the posterior part of the hippocampal gyrus (entorhinal area of Brodmann) or to the hippocampus itself (Rose and Woolsey, 1943; Fox, McKinley and Magoun, 1944; Le Gros Clark and Meyer, 1947; Meyer and Allison, 1949). Thus the function of the hippocampus remains obscure, and it becomes important to determine the possible existence of tertiary olfactory paths. These might pass from the prepiriform cortex to the hippocampus directly, or to the entorhinal area and thence by a further relay to the hippocampal formation through the temporo-ammonic tracts of Cajal. Much of the present study has been directed to the investigation of this hypothesis. The attention of other workers has been focused on certain functional aspects of the temporal lobe. Bucy and Kluver (1940) reported a condition after extensive temporal lobectomy in monkeys which they described as" psychic blindness"—an inability to appreciate the significance of things seen or heard without any measurable defect in actual perception. The emotional response to rage or fear-provoking stimuli was diminished or abolished. Bard and Mountcastle (1948) have shown that lesions in the amygdalae and hippocampi in cats are followed by altered emotional responses. Blum, Chow and Pribram (1950) found that temporal lobectomy in the monkey led to altered tractability to human handling and also to defective learning ability in problems involving visual discrimination.
