Virtual Reality installed with a Femto2D

Virtual Reality - Jet Ball from PhenoSys installed with a Femto2D microscope


The Jet Ball is a novel virtual reality experimental system. It is based on an air supported spherical treadmill, and allows a restrained animal to navigate in virtual space. Virtual reality provides a perfectly controllable experimental environment, and can be used for investigating navigation, cognition, learning and memory.

Restrained animals can be examined with electrophysiological and optogenetic methods while the animal performs simple or complex behaviours.  

    


虚拟实境与双光子激光共聚焦、激光共聚焦荧光显微镜记录
头颅固定与虚拟实境相搭配:科研界首次能在自由活动的动物大脑中,稳定地采集到细胞影像!
 
特点说明:
与活体膜片钳记录相同,活体双光子记录目前为止都是在麻醉动物身上进行,动物麻醉后无法模拟真实环境下对外界刺激的反应。因此最好的实验系统是在活动动物身上做记录。既要能让动物自由活动完成任务,又要维持稳定性记录大脑皮层的细胞形态,可通过虚拟实境系统能完成这项任务。虚拟实境系统采用头颅固定方式,搭配视觉、嗅觉、听觉、味觉、与触觉等所有与真实环境相似的外界刺激,让动物在三维空间中自由运动。同时搭配无限可能的迷宫设计,在狭小的实验室空间内模拟了各种可能的迷宫,大大增加了空间自由度

  • Custom programmed operant conditioning protocols and VR scenes
  • Base with motor-driven XY linear table for large area brain scanning with 2-photon laser



虚拟实境与电生理膜片钳记录
