Neuroscience studies of unconstrained, large animal behavior can reveal rich neural activity associated with movement. To date, no motion capture platform sufficiently sized to record natural movement and controlled using a single computer has been reported. Addressing this need, we constructed a 2.1 x 2.1 x 2.4 m enclosure outfitted with a low-cost, end-to-end recording system capable of collecting hours of hardware-synchronized, multi-camera depth and RGB data, acquired at rates >250 MBps using a single Linux desktop. With this platform--which is readily implemented and capable of capturing a wide range of natural behaviors--kinematics can be extracted and combined with simultaneously acquired, wireless, intracranial neural recordings, providing novel insights into the functioning of the mammalian motor system.
