Development of a Compact Apparatus for Measuring Visually Induced Eye Movements in Larval Fish

Abstract

Visually induced eye movements in larval fish, especially those in zebrafish have been intensively studied to understand neural mechanisms of sensory-motor transformation and motor learning. In this study, we developed a compact system for measuring eye movements in larval fish induced by visual stimuli using a small single-board computer, Raspberry Pi. The system features an integration of multiple displays for presenting visual stimuli and a camera for measuring binocular eye movements, both controlled by a Raspberry Pi.
