Instabilities during antiphase bimanual movements: are ipsilateral pathways involved?

abstract：:Multisensory integration is known to create a more robust and reliable perceptual representation of one's environment. Specifically, a congruent auditory input can make a visual stimulus more salient, consequently enhancing the visibility and detection of the visual target. However, it remains largely unknown whether ...
