Technique for studying of operant reflexes in animals under visual pursuit of target objects was developed. Device suggested allows to study both motor postural processing and the sensory target completion in animals, excluding any possibility of chaotic motor activity and attempts to avoid performing of sensory-motor task. The device gives a good opportunity for animals to perform the sensory-motor goal directed task with di erent speed and time in autonomous regime without participation of experimenter.

Key words: operant behavior, motor postural reflexes, visual pursuit, sensory-motor task, eye-head coordination, sensory completion
