To understand the origins of spatial navigational signals, Acharya et al. record the activity of hippocampal neurons in rats running in open two-dimensional environments in both the real world and in virtual reality. They find that a subset of hippocampal neurons have directional tuning that persists in virtual reality, where vestibular cues are absent.
为了理解空间导航信号的起源,阿查里亚等人记录了大鼠在现实世界和虚拟现实中的二维开放环境中奔跑时海马神经元的活动。他们发现,海马神经元的一个子集具有方向调谐,这种调谐在没有前庭线索的虚拟现实中依然存在。
