Topic: proprioceptive information

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

The mammalian brain continuously integrates sensory and proprioceptive information. This dynamic process enables adaptation to rapidly changing environments and is critical for perception and action selection. However, the exact underlying neuronal computations remain poorly understood, particularly in freely moving animals where behavioral and sensorial transitions are rapid. Relating neural activity to natural behavior has been technically challenging due to a lack of tools to quantify postural dynamics at ethologically relevant timescales. Furthermore, sensory systems have traditionally bee
