发声的自主控制是言语进化中的一项重要成就。在人类中，腹侧前运动皮层 (PMv) 和布罗卡区已知参与自主发声。相比之下，没有关于非人类灵长类 PMv 口面部部分在此功能中的作用的神经生理学数据。为了解决这个问题，我们记录了两只经过训练发出咕咕叫声的猴子的 PMv 神经元。结果表明，一群运动神经元在发声期间特别放电。大约三分之二的人在声音出现之前放电，而其余的则与声音同步。发声选择性神经元的反应仅在条件（自愿）声音发射期间出现，而不是自发（情感）声音发射期间出现。这些数据表明，PMv 神经元对发声的控制构成了猴谱系中新出现的特性，为非人类灵长类物种基于发声的交流的进化提供了线索。
The voluntary control of phonation is a crucial achievement in the evolution of speech. In humans, ventral premotor cortex (PMv) and Broca's area are known to be involved in voluntary phonation. In contrast, no neurophysiological data are available about the role of the oro-facial sector of nonhuman primates PMv in this function. In order to address this issue, we recorded PMv neurons from two monkeys trained to emit coo-calls. Results showed that a population of motor neurons specifically fire during vocalization. About two thirds of them discharged before sound onset, while the remaining were time-locked with it. The response of vocalization-selective neurons was present only during conditioned (voluntary) but not spontaneous (emotional) sound emission. These data suggest that the control of vocal production exerted by PMv neurons constitutes a newly emerging property in the monkey lineage, shedding light on the evolution of phonation-based communication from a nonhuman primate species.
