Visiobox - OKR for larvae

Zebrafish visual behavior & OptoKinetic Response test to measure visual accuity on multiple Zebrafish. Black and white stripes are rotating with differents speed adjustable.

OptoMotor response (OMR) is a reflex behavior observed, when an animal follow naturally a rotating grating around it. It has been widely used to assess the visual functions of zebrafish. However, the standard protocol for larval fish is not yet applicable in adult zebrafish

The optomotor response of zebrafish is a reflex to stabilize the body position in a moving environment Optomotor response measurements are done using a moving grating as stimulus that is presented by our sytstem. A fullscreen squarewave grating, which moves left- or rightwards. The user can adjust speed, contrast, number of stripes. ZOMR is a component of ZebraLab and ZebraBox and allows the automated observation and tracking of zebrafish larvea visual behavior in a freely moving environment.
