Topic: orthogonal neural subspaces

Constant interactions of motor and sensory signals occur at many levels in the nervous system to support animals’ adaptive behaviors. During movements, motor brain regions not only send motor commands to descending spinal pathways, but also corollary discharge (CD) signals to other brain areas to modulate sensory processing. Theoretical work suggests the sensory predictions conveyed by CD signals are combined with sensory feedback to form an optimal estimate of the body state. However, neural underpinnings of this integration in cortex remain elusive. Here, we used a neural decoding-based appr
