“…Similarly, Cordeau and Mahut (1964) found that in a long-term study of post-ablation temporal lobe deficits on complex auditory and visual discrimination tasks in monkeys, some animals appeared to show recovery of functions after a number of years.…”

“…Object discrimination learning was one of the few memory tasks available for use by early investigators of amnesia in monkeys; the repeated finding that object discrimination learning could be performed normally by monkeys after lesions thought to be similar to those which produce amnesia in man (Orbach er al., 1960;Kimble and Pribram, 1963;Cordeau and Mahut, 1964;Gaffan, 1974;Malamut et al, 1984; see also Gaffan and Lim, 1991) has been a paradox to which many different unsuccessful solutions have been proposed. For example, proposals to the effect that object discrimination learning tasks test some functionally distinct form of memory, different from the type of memory which is impaired in human amnesia (e.g.…”

Amnesia for Complex Naturalistic Scenes and for Objects Following Fornix Transection in the Rhesus Monkey

Rhesus monkeys (Macaca mulatta) were trained to discriminate among many complex naturalistic scenes. The scenes were still frames from a cinema film. They were presented as the discriminative stimuli in a concurrent discrimination learning task in which each discriminative stimulus was presented on one trial each day. Learning of this task was severely impaired by fornix transection. The same animals were also deficient in a similar concurrent discrimination learning task, with each discriminative stimulus presented on one trial each day, but with objects, not complex scenes, as the stimulus material. The impairment in object discrimination learning in the present experiment is attributable to an interaction of object discrimination learning with scene discrimination learning, and can be understood as an effect of interference in long-term memory. In contrast to these impairments in long-term memory, a test of within-session learning of complex scenes, in which the average interval between successive presentations of the same stimulus was < 3 min, was performed without significant impairment by the fornix-transected animals. These results show that long-term memory for complex naturalistic scenes reveals analogues in the monkey of human episodic memory and its impairment in amnesia.

“…Consistent with this possibility is the finding that before the operation, the animals generalized immediately from auditory clicks to visual flashes of the same frequency. Second, and more importantly, a 2-year follow-up study (Cordeau and Mahut, 1964) revealed no auditory DMS deficit but rather a visual DMS impairment, a finding not surprising given that the "auditory cortex" lesion actually included the dorsal part of IT cortex and the temporal pole and in fact very little of the ST cortex.

The Effects of Superior Temporal Cortex Lesions on the Processing and Retention of Auditory Information in Monkeys (Cebus apella)

Three monkeys with extensive preoperative training on visual and auditory memory tasks (delayed matching-to-sample), an auditory pattern-discrimination task, and a visual serial-order task, received bilateral lesions of the superior temporal (ST) cortex in two stages, with testing after each lesion. Unilateral ST cortex lesions resulted in only moderate auditory memory impairments, whereas bilateral ST cortex lesions resulted in severe auditory memory impairments. The bilateral ST cortex lesions also resulted in severe impairments in the ability to relearn the auditory pattern-discrimination task. In contrast to the auditory impairments, neither unilateral nor bilateral ST cortex lesions had any effect whatsoever on either visual memory or visual serial-order behavior. These findings indicate that the ST cortex plays a role in auditory processing and retention similar to that played by the inferior temporal cortex for visual processing and retention.
