标准的动物行为范式不完全模仿自然,限制了我们对行为和大脑功能的理解。虚拟现实(VR)可以提供帮助,但也带来了挑战。典型的虚拟现实系统需要限制运动,但会破坏感觉运动体验,导致神经元和行为改变。我们报告了自由移动动物的虚拟现实系统FreemoVR的开发。我们验证了小鼠、苍蝇和斑马鱼的沉浸式VR。FreemoVR通过允许即时,无干扰的环境重新配置以及真实生物体和计算机控制的代理之间的相互作用,实现了新型实验。这使我们能够在小鼠中建立高度厌恶试验,并发现果蝇和斑马鱼的视觉运动效应。此外,通过模拟逼真的斑马鱼,我们发现有效的社会影响力取决于潜在领导者在其内部偏好的方向选择与社会互动之间的平衡。FreemoVR技术可以通过对不受约束动物的感觉运动反馈回路的精确操作,对神经功能和行为进行详细的调查。
Standard animal behavior paradigms incompletely mimic nature, limiting our understanding of behavior and brain function. Virtual Reality (VR) can help, but poses challenges. Typical VR systems require movement restrictions but disrupt sensorimotor experience, causing neuronal and behavioral alterations. We report the development of FreemoVR, a VR system for freely moving animals. We validate immersive VR for mice, flies and zebrafish. FreemoVR enables new types of experiments by allowing instant, disruption-free environmental reconfigurations and interactions between real organisms and computer-controlled agents. This allows us to establish a height aversion assay in mice and to discover visuomotor effects in Drosophila and zebrafish. Furthermore, photo-realistically mimicking zebrafish, we discovered that effective social influence depends on a prospective leader balancing its internally preferred directional choice with social interaction. FreemoVR technology allows detailed investigations into neural function and behavior by the precise manipulation of sensorimotor feedback loops in unrestrained animals.
