虽然众所周知，灵长类动物的大脑进化是为了应对复杂的社会突发事件，但灵长类动物中社会互动的神经生理表现还没有被很好地理解。在这里，来自两对猴子的并行无线神经元集成记录被用来测量在一项涉及两只猴子持续社会互动的全身导航任务中的大脑皮层同步(ICS)。一只猴子，即乘客，被机器人轮椅抬到食品自动售货机前，而另一只猴子，即观察者，则静止不动，看着乘客。这两只猴子轮流扮演乘客和观察者的角色。来自猴子运动皮质和运动前背侧区域的同步神经元集合记录显示，ICS的发作性发生的可能性取决于轮椅运动学、乘客-观察者距离和乘客-食物距离--这些都是之前在行为研究中描述的社会交互因素。这些结果表明，ICS代表了灵长类社会交往的特定方面。
While it is well known that the primate brain evolved to cope with complex social contingencies, the neurophysiological manifestation of social interactions in primates is not well understood. Here, concurrent wireless neuronal ensemble recordings from pairs of monkeys were conducted to measure interbrain cortical synchronization (ICS) during a whole-body navigation task that involved continuous social interaction of two monkeys. One monkey, the passenger, was carried in a robotic wheelchair to a food dispenser, while a second monkey, the observer, remained stationary, watching the passenger. The two monkeys alternated the passenger and the observer roles. Concurrent neuronal ensemble recordings from the monkeys’ motor cortex and the premotor dorsal area revealed episodic occurrence of ICS with probability that depended on the wheelchair kinematics, the passenger-observer distance, and the passenger-food distance – the social-interaction factors previously described in behavioral studies. These results suggest that ICS represents specific aspects of primate social interactions.
