在 16 只松鼠猴 (S. sciureus) 中研究了双侧皮质面部区域、前后辅助运动区和前扣带皮层破坏对自发发声的影响。每种类型的损伤分为 2 组，每组 2 只动物。一组中的两只动物在同一天都受到相同类型的损伤。每组术前1 h记录10次，术后10次记录。比较术前和术后发声的总数和声学结构。根据超声分析判断，没有任何病变影响声学结构。前辅助运动区（胼胝体膝部水平）的病变显着减少了总发声次数。这种减少主要是由于所谓的隔离窥视（长途联系电话）的大幅减少。面部皮层区域显然只参与控制习得的声音表达（例如人类言语和歌曲），而不参与产生基因预编程的表达（例如猴子的叫声和人类痛苦的呻吟）。前扣带皮层可能对于有意识地发起发声是必需的，但对于在情绪情况下发起呼叫则不是必需的。后辅助运动区显然在猴子的发声行为中不起任何作用。前部辅助运动区可能参与发声的产生，这些发声不是由外部事件直接触发的。
The effects of bilateral destruction of the cortical face area, anterior and posterior supplementary motor area and anterior cingular cortex on spontaneous vocalization were studied in 16 squirrel monkeys (S. sciureus). Each type of lesion was made in 2 groups of 2 animals each. Both animals of a group received the same type of lesion at the same day. Each group was recorded for 10 sessions of 1 h before operation and 10 sessions after operation. Pre- and post-operative vocalizations were compared in respect to total number and acoustic structure. None of the lesions affected acoustic structure as judged by sonagraphic analysis. Lesions in the anterior supplementary motor area (at the level of the callosal genu) reduced the total vocalization number significantly. This decrease was essentially due to a drastic reduction of the so-called isolation peep, a long-distance contact call. The cortical face area is apparently only involved in the control of learned vocal utterances (such as human speech and song) but not in the production of genetically preprogrammed utterances (such as monkey calls and human pain groans). The anterior cingulate cortex is probably necessary for the volitional initiation of vocalization but not for the initiation of calls in an emotional situation. The posterior supplementary motor area does not apparently play any role in vocal behavior of monkeys. The anterior supplementary motor area may be involved in the production of vocalizations which are not triggered directly by external events.
