在4只日本猕猴中测定了小的双侧皮质病变对纯音听力图和区分两种类型的日本猕猴咕咕声的能力的影响。病变包括两个半球的上级颞回的中部，即初级和次级听觉区，导致部分听力损失以及无法区分发声。病变包括两侧半球的上级颞回的腹侧部分，但保留一侧的听觉皮层也会导致部分听力损失，但对辨别发声的能力影响很小或没有影响。双侧背侧上级颞回和邻近的顶叶和枕叶区域的消融不会导致听力损失，并且对辨别发声的能力没有影响。结果表明，听力损失可能产生的病变，涉及双侧上级颞回腹侧三分之二的一小部分，虽然所造成的损失是没有那么大的病变观察。然而，失语症样缺陷似乎是由初级和/或次级听觉皮层病变引起的。（PsycInfo数据库记录（c）2020阿帕，保留所有权利）
The effect of small bilateral cortical lesions on pure-tone audiograms and on the ability to discriminate between two types of Japanese macaque coo vocalizations was determined in 4 Japanese macaques. A lesion that included the middle portion of the superior temporal gyrus of both hemispheres, that is, the primary and secondary auditory areas, resulted in a partial hearing loss as well as an inability to discriminate the vocalizations. Lesions that included the ventral portions of the superior temporal gyrus of both hemispheres but spared auditory cortex on one side also resulted in a partial hearing loss but had either a small effect or no effect on the ability to discriminate the vocalizations. Bilateral ablation of the dorsal superior temporal gyrus and adjacent parietal and occipital areas did not result in a hearing loss and had no effect on the ability to discriminate the vocalizations. Results suggest that a hearing loss may be produced by lesions that involve small portions of the ventral two-thirds of the superior temporal gyrus bilaterally although the resulting loss is not as great as that observed with larger lesions. However, the aphasia-like deficit appears to result from a lesion of primary and/or secondary auditory cortex.(PsycInfo Database Record (c) 2020 APA, all rights reserved)
