The magnitude of hand-blink reflex is increased by tonic cortico-spinal activation.
This effect is smaller than the commonly observed HBR increase when the stimulated hand is near the eye.
Nonetheless, when using HBR as an indicator of behavioural relevance, this effect should be taken into account.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
