Optomotor assay
WebJan 1, 2012 · The assays described below rely on optomotor responses, direction-selective changes in head or body movement. The optomotor response is usually thought of as a stabilizing reflex, as flies will attempt to turn their heads or bodies to minimize visual slip when presented with a rotating grating ( 1 , 2 ). WebDec 13, 2024 · We assessed the optomotor response (OMR) of larval zebrafish by analyzing the swimming responses (entrainment) to repeated sinewave gratings moving in one direction, and then reversing the...
