研究了醒鼠猴上丘42个细胞对纯音和7种不同种类的发声的反应。36个细胞对至少一种听觉刺激有反应。在应答细胞中，94%对至少一种发声有反应。纯音的效果较差，只有69%的人会做出回应。根据有效带宽，细胞可分为2个亚组：带宽为0.08-2倍频的窄调谐细胞和带宽为4-6倍频的宽调谐细胞。所有窄调谐细胞对有效频率的反应都是简单、短暂和相似的模式。大多数广泛调谐的细胞表现出更复杂，更长的响应模式，这是频率依赖的。不同的声音在大多数细胞中引起简单、短暂和相似的反应模式。在一些细胞中，这些声音引发了更复杂、更长和不同的反应模式。在窄调谐和宽调谐细胞中，表现出简单和短模式的细胞均匀分布。所有对发声表现出更复杂反应模式的细胞都是广泛调谐的。
Forty-two cells in the superior colliculus of awake squirrel monkey (Saimiri sciureus) were tested for their responses to pure tones and to 7 different species-specific vocalizations. Thirty-six cells responded to at least 1 of the auditory stimuli. Of the responding cells 94% responded to at least 1 vocalization. Pure tones were less effective and elicited a response in only 69%. Based on the effective bandwidths, cells could be divided into 2 subgroups: narrowly tuned cells with bandwidths of 0.08-2 octaves, and broadly tuned cells with bandwidths of 4-6 octaves. All the narrowly tuned cells responded to the effective frequencies with simple, short and similar patterns. Most of the broadly tuned cells exhibited more complex, and longer response patterns which were frequency-dependent. The various vocalizations elicited simple, short and similar response patterns in most cells. In several cells these vocalizations elicited more complex, longer and different response patterns. Cells which exhibited simple and short patterns in response to vocalizations were evenly distributed among the narrowly and broadly tuned cells. All the cells which exhibited the more complex response patterns to vocalizations were broadly tuned.
