Ocular Videography System
First Claim
1. An ocular videography system for tracking eye movements of an animal comprising:
- a) a camera system suitable for being positioned on a head of an animal to track eye movements of at least one eye of the animal, said camera system comprising at least one image sensor as well as at least one decoder for decoding a signal detected by the image sensor, wherein the at least one decoder is physically separate from the at least one image sensor;
b) a head mount on which the camera system is fixed or fixable, wherein the camera system is designed in such a way to detect movements of the eye and/or a movement of the head of the animal in a vertical direction, horizontal direction, torsional direction, or combinations thereof, relative to an optical axis of the camera system or the optical axis of the eye of the animal, or both, without interfering with natural motion dynamics of the animal; and
c) a head position tracking system designed to track a position of the head of the animal within a predefined, stationary coordinate system originating outside of the body of the animal, wherein said head position tracking system comprises three tracking arms mounted on the head mount in a predefined position to each other, wherein each of the tracking arms comprises one or more light emitting elements, and the head position tracking system further comprises a head movement detection device mounted off of the body of the animal and stationary within the coordinate system, wherein the head movement detection device is able to detect movement of the tracking arm light emitting elements and is able to calculate a position of the head of the animal within said stationary coordinate system according to position and/or movement of the tracking arm light emitting elements.

Abstract
The present invention relates to an Ocular Videography System for tracking eye movements of an animal, in particular rats, comprising a camera system suitable of being positioned on the head of an animal to track eye movements of at least one eye of the animal, a head mount on which the camera system is fixed or fixable, wherein, at least one image sensor as well as at least one decoder, for decoding a signal detected by the image sensor, each being comprised by the camera system, and wherein the camera system, and in particular a camera of the camera system, is designed in such a way that it detects a movement of the eye and/or a movement of the head of the animal in a vertical and/or horizontal and/or a torsional direction to an optical axis of the camera system and/or of the optical axis of the animal'"'"'s eye without interfering with the animal'"'"'s natural motion dynamics.
