DESCRIPTION:Speaker: Andrew Straw\nhosted by Maximilian Jösch\nAbstract: U
 nder natural circumstances\, brains control locomotion in the context of t
 he action perception cycle\, and movement modulates input across many sens
 ory modalities. While neural circuits have evolved in such closed-loop con
 ditions\, many powerful techniques to study sensory processing operate on 
 restrained animals and thus may be limited to situations in which the anim
 al is not experiencing natural multi-modal coupling of sensory input with 
 motor output. To overcome this challenge\, we have developed a visual virt
 ual reality system called FreemoVR which allows the experimenter to create
  precisely defined immersive\, 3D visual surroundings for freely moving an
 imals and we validated its use on mice\, fish and flies. Taking advantage 
 of the completely automated nature of this system and recent developments 
 in neurogenetic tools in the fly Drosophila\, we performed a screen for ne
 ural circuits specifically involved in processing of visual motion resulti
 ng from with either translational and rotational self-motion. Our findings
  confirm the importance of fundamental motion detecting neurons such as T4
  and T5 cells for both tasks. Furthermore\, we discovered other circuit el
 ements which are involved in specific components of flight control. Taken 
 together\, this work illustrates how we may gain insight into the structur
 e and function of neural circuits even in freely moving animals.
