Different sensory information is used for state estimation when stationary or moving.

The estimation of limb state involves feedforward and feedback information. While estimation based on feedback has been well studied when the limb is stationary, it is unknown if similar sensory processing supports limb position estimates when moving. Using a behavioral experiment and computational model, we show that feedback-based state estimation may involve multisensory integration in the static case, but it is likely based on a single modality when the limb is moving. This difference may stem from visual and proprioceptive feedback delays.
