- W4288791978 abstract "Abstract Social interactions powerfully impact the brain and the body, but high-resolution descriptions of these important physical interactions are lacking. Currently, most studies rely on labor-intensive methods such as manual annotation. Scalable and objective tracking methods are required to understand the neural circuits underlying social behavior. Here we describe a hardware/software system and analysis pipeline that combines 3D videography, deep learning, physical modeling, and GPU-accelerated robust optimization, with automatic analysis of neuronal receptive fields recorded in interacting mice. Our system is capable of fully automatic multi-animal tracking with minimal errors (including in complete darkness) during complex, spontaneous social encounters, together with simultaneous electrophysiological recordings. We capture posture dynamics of multiple unmarked mice with high spatiotemporal precision (~2 mm, 60 frames/s). A generative model revealed the multiplexed ‘social receptive field’ of neurons in barrel cortex. This approach could be broadly useful for neurobehavioral studies of multiple animals interacting in complex low-light environments." @default.
