The jaw-opening (digastric) reflex was elicited by electrical stimulation of oral mucosa in miniature pigs (Sus scrofa) varying in age from 5 days premature to 101 days post-term. The latency of reflex electromyographic activity varied between 12-14 ms in the most immature animals and 9-11 ms in the oldest animals. The very long-latency digastric responses found in the immature young of nesting mammals were not seen in the relatively precocious young of this species.
通过电刺激年龄从早产5天到足月后101天不等的小型猪（野猪）口腔黏膜来引发张口（二腹肌）反射。在最年幼的动物中，反射肌电图活动的潜伏期在12 - 14毫秒之间，而在最年长的动物中为9 - 11毫秒。在筑巢哺乳动物的未成熟幼崽中发现的极长潜伏期二腹肌反应，在该物种相对早熟的幼崽中未观察到。
