Time-based prediction in motor control: evidence from grip force response to external load perturbations.

abstract：:The specificity of adaptation of vestibulo-ocular reflex direction was examined by exposing cats to combined pitch vestibular rotation and horizontal optokinetic motion at 0.25 Hz, while alternating body position between lying on the left side and lying on the right. The direction of optokinetic motion relative to hea...
