This paper investigates how startling acoustic stimuli shorten reaction times in reflexive reaching tasks by enhancing express visuomotor responses without altering their timing.

This study shows that Rhesus Macaques exhibit express visuomotor responses in upper limb muscles with latencies of ~65 ms, similar to humans but faster, suggesting shared but distinct visuomotor transformation mechanisms.

The paper shows express arm responses occur bilaterally in upper-limb muscles during reaching tasks, supporting the involvement of the reticulo-spinal tract.

This paper introduces a new behavioral paradigm that consistently evokes robust fast visuomotor responses in human upper limb muscles during visually guided reaches.

This study investigates how superior colliculus neurons encode target motion during saccades, finding that their movement fields shift in the direction of target motion but not for future locations.
