猴子对听觉序列的辨别

我们曾成功地训练恒河猴区分两个元素听觉序列的四种排列，其中每个元素可以是音调的爆发或噪音的爆发。这是一项异常复杂的任务，因此应该证明对中枢神经系统的操纵敏感。事实上，在目前正在进行的实验中，已经发现猴子在单侧切除上级颞回皮层（听觉“联合”皮层）后，其辨别能力出现严重缺陷。
WE have been successful in an attempt to train rhesus monkeys to discriminate among the four permutations of a two element auditory sequence in which each of the elements can be either a burst of tone or a burst of noise. This is an unusually complex task and as such should prove sensitive to manipulations of the central nervous system. Indeed, in experiments now under way, severe deficits have been found in the discrimination performance of monkeys following unilateral ablations of the cortex of the superior temporal gyrus (auditory “association” cortex).
