Cats trained to discriminate between the speech sounds [u] and [i] do not retain and are unable to relearn this discrimination after bilateral ablation of the ventral insular-temporal cortex. In control animals, retention of this ability is not affected by bilateral removal of primary auditory receiving cortex.
Ten monkeys were trained on two auditory discrimination problems of different levels of difficulty plus one visual pattern discrimination task. Bilateral conical ablations were made of either the ventral portion of the superior tem· poral gyrus to the depth of the superior temporal sulcus in the midtemporal region, or of the primary auditory projection… (More)
The first auditory recall functions have been derived for monkeys; the same animals also demonstrate perceptual abilities closely approximating those of man. An efficient, powerful psychophysical technique is used to specify and force predicted levels of difficulty of task performance across time, animals, and problems.
Three adult cats were deprived of rapid eye movement sleep for six separate periods of up to 32 days. Animals were allowed normal amouints of sleeping time during which rapid eye movement sleep was interrupted, whenever it occurred, by human observers who continually monitored the animals and their electrocortical activity. Cortical responses evoked by… (More)
