Abstract

The blink reflex is a reflex contraction of the orbicularis oculi muscles that can be a elicited by visual, acoustic, tactile and electrical stimuli. The electrically evoked orbicularis oculi reflex (EBR) consists of an early ipsilateral oligosynaptic response R1, and a late bilateral polysynaptic response R2. The EBR has been studied extensively in patients with impaired consciousness (2).
