A perspective on multisensory integration and rapid perturbation responses

摘要: Abstract In order to perform accurate movements, the nervous system must transform sensory feedback into motor commands that compensate for errors caused by variability and external disturbances. Recent studies focusing on importance of in control have illustrated brain generates highly flexible responses visual perturbations (hand-cursor or target jumps), following mechanical loads applied limb. These parallel approaches emphasized sophisticated, goal-directed control, but also reveal perturbation are expressed at different latencies depending what is engaged perturbation. Across studies, visuomotor consistently emerge muscle activity ∼100 ms after a perturbation, while evoke as little ∼60 ms (long-latency responses). We discuss limitation current models multisensory integration light these asynchronous processing delays, suggest understanding how performs real-time an open question future studies.
