When the unaffected facial nerve was stimulated in 30 patients with facial palsy, evoked action potentials could be recorded from the contralateral (paralysed) perioral muscles. Similarly, in four normal subjects responses were evoked contralateral to the stimulated facial nerve. The latency of these responses in the patients remained unchanged over several months, and they were conducted at a rate compatible with conduction along muscle fibres. The contralateral responses are suggested to be due to conduction along muscle fibres crossing the midline rather than to cross-innervation.
在30例面瘫患者中，当刺激未受影响的面神经时，可从对侧（麻痹的）口周肌肉记录到诱发性动作电位。同样，在4名正常受试者中，刺激面神经对侧也可诱发反应。患者这些反应的潜伏期在几个月内保持不变，并且它们的传导速度与沿肌纤维的传导速度相符。对侧反应被认为是由于沿跨越中线的肌纤维传导所致，而非交叉神经支配。
