“…Considerable evidence exists that the behavioral consequences of brain damage are minimized when the injury occurs early in life. This "sparing" has been observed following damage to numerous cortical structures (e.g., Beach, 1938;Benjamin & Thompson, 1959;Franzen & Myers, 1973;Harlow, Blomquist, Thompson, Schiltz, & Harlow, 1968;Kling & Tucker, 1968;Scharlock, Tucker, & Strominger, 1963;Tsang, 1937;Wetzel, Thompson, Horel, & Meyer, 1965).…”

At 6 yr of age six female rhesus monkeys that had sustained bilateral amygdalectomy in infancy, and five intact controls, were transferred to an observation cage where behaviors were recorded while the monkeys were (a) alone, (b) paired with unfamiliar stimulus animals, and (c) paired with familiar monkeys from the opposite experimental group. The five adult controls then underwent amygdalectomy, and all tests were repeated with the infant-and adult-operated animals. Infant-operated monkeys changed behaviors more rapidly than did intact controls in social and nonsocial situations, and their activity levels were less modified after a 24-hr period in the observation cage. They were subordinate to intact controls but expressed less fear than did controls when briefly placed with an unfamiliar aggressive animal. Adult amygdalectomy produced many changes in behavior, but these aberrations were identical to those observed in like-age monkeys that had been amygdalectomized in infancy. Infant-operated monkeys demonstrated more behavioral deficits at 6 yr than they had earlier in life.

“…DuVerney (55), in 1683, likened the cochlea to a musical instrument with different parts responding to tones of different pitch according to the principles of physical resonance. He assumed that the lamina spiralis was the vibrating mechanism and, since this bony plate is broader in the basal coil and becomes gradually narrower towards the apex of the cochlea, he located perception of low tones in the basal coil and of higher tones in the apex (162). f I r Scarpa (156), in 1798, discovered the membranous labyrinth, and Corti (32), in 1851, discovered the details of the end organ in the cochlea, which now bears his name.…”

“…All of the previous studies that report frequency discrimination after removing various auditory areas of the cortex have used adult cats. Sharlock, Tucker, and Strominger (162) reported that large bilateral lesions in the auditory cortex of infant cats did not prevent them from learning a tonal-pattern discrimination; but adult cats with comparable damage did not acquire this discrimination. The authors concluded that neonatal damage to the auditory cortex appears to be less damaging than comparable damage at maturity.…”

This paper is a comprehensive review of auditory theory and research that bear directly or indirectly on pitch perception. It considers pitch perception from three major points of view. First, it reviews the history of pitch-perception studies and describes some representative theories of hearing they have " engendered. Second, this paper examines various auditory phenomena in the light of how well the different theoretical positions can explain them. Finally, it attempts to collate physiological and anatomical findings about the auditory nervous system and, again, use the facts which emerge to test the adequacy of theoretical concepts and explanations. The 213 references include studies of both humans and animals.

Interactive Effects of Age and Brain Disease on Reaction Time

Simple visual and auditory reaction time (RT) was studied in younger (16 to 44 years old) and older (46 to 63 years old) control and brain-diseased patients. Differences in RT related to age were larger for brain-diseased than control patients. Differences in RT related to diagnostic category were larger for older than younger patients. Analysis indicated an interactive effect of age and brain disease on RT supporting the suggestion that acquired brain disease leads to a more pronounced retardation in RT in older patients.
