Story summary

A Nature study shows the brain's motor circuits actively prepare for movement by anticipating potential disturbances.
Jonathan A. Michaels, lead researcher, finds sensory expectations significantly improve reaction times and accuracy during unexpected mechanical perturbations.
Using advanced computational models and high-density neural recordings from humans and monkeys, the study shows the motor cortex adjusts preparatory states based on probabilistic cues about disturbances.
