醒着的松鼠猴的听觉皮层（AC）单元对自然序列的响应性与对序列反向播放的响应性无显著差异。响应单位的百分比与声音的平均强度、频谱含量或呈现顺序之间没有关系。即使是在一个不变的行为环境中产生的序列，声音引起反应的效果也是不同的。将这些发现与早期正常或孤立的个体发声的结果进行比较，表明交流神经元对连续声音的反应性低于它们对孤立声音的反应性，无论是自然的还是人工的。
Responsiveness of auditory cortex (AC) units of awake squirrel monkeys to a natural sequence of species-specific calls was not significantly different from their responsiveness to a reverse playback of the sequence. No dependence was noted between the percentage of responding units and the average intensity of sounds, their spectral content or their order of presentation. The effectiveness of the sounds in eliciting responses was variable even when the sequence was produced in an unchanging behavioral context. Comparison of these findings with earlier results of individual vocalizations presented normally or backward in an isolated manner suggests that responsiveness of AC neurons to continuous sounds is lower than their responsiveness to isolated sounds, whether natural or artifical.
