The TOM – Freely Moving Monkey (TOM – FMM) system is a fully-integrated device for the non-invasive measurement of eye movements in freely behaving and moving non-human primates. Due to its superior quality and plug-and-play handling, it is ideally suited for basic oculomotor research in non-human primates. The TOM FMM is a system that allows to measure body position and pose as well as eye movement parameters from freely moving non-human primates in a transparent cage. The primate is housed temporary in the rugged cage and 5 high resolution and high-speed video cameras equipped with wide range lenses capture the animal in real-time. The non-invasive, contact-free measurement principle requires no special accustoming from the animal, reduces stress and the animal’s well-being, increases the speed of training and the animal´s performance. The TOM FMM allows to present visual stimuli from all spatial directions without annoying cage bars and to record the full 3-D gaze direction of the freely moving animal. The non-invasive, contact-free measurement principle requires no special accustoming from the animal and allows an easy combination with other neuroscientific techniques like telemetric electrophysiological recordings.
