Corticospinal circuit plasticity in motor rehabilitation from spinal cord injury.

abstract：:We investigated whether the presence of unimodal or bimodal (synchronous) distractors would affect temporal order judgments (TOJs) for pairs of asynchronous audiovisual target stimuli. Participants made unspeeded TOJs regarding which of a pair of auditory and visual stimuli, presented at different stimulus onset async...
