Crossed R1 response of the blink reflex in peripheral facial palsy.
A patient with regenerated Bell's palsy showed a crossed R1 component of the blink reflex recorded from the healthy side while stimulating the affected side. Our observation supports the hypothesis that a short-circuit trigemino-facial pathway crossing the midline exists in normal subjects which is not activated under normal conditions, but may be engaged following peripheral facial nerve disease.
