Abstract

A system for precise recording of eye position and movements in laboratoryanimals, by means of Hall-effect devices, is described. The system, usefulin neurophysiological and neurobehavioral studies, allows the analysis of saccadic eye movements, optokinetic- and vestibular-induced nystagmus, slowtracking movements, eye vergences, and so forth. This small, light-weight,and inexpensive system uses a set of Hall-effect devices and associated electronics to sense variations in the position of high-power magnets fixed in the eye sclera or in scleral contact lenses. The output of the Hall-effect devices is amplified by operational amplifiers, collected through an A/D converter, and analyzed in a PC computer by specific software.
