Unilateral lid restraint alters trigeminal reflex blinks. A, The relative amplitudes of a blink (Condition) evoked by a 2T SO stimulus (dotted line SO) and a blink (Test) elicited by an identical SO stimulus (dotted line SO) 500 msec later are different before (Pre) and after (Post) 165 min of upper eyelid restraint. After lid restraint, a single 2T SO stimulus evokes a reflex blink and additional blinks (Blink Oscillation) that occur at a constant time relative to the onset of the preceding blink. Each trace is a single trial from the left eyelid. B, The relative amplitudes of left lid (solid line) and right lid (dashed line) movement evoked by a left SO (LSO) or right SO (RSO) stimulus are different before (Pre) and after (Post) 2 hr of left upper eyelid restraint. Each trace is a single trial.
