Reflex activity was induced in the digastric and other submandibular muscles of pre-weaning rats, rabbits, cats and guinea pigs by electrical stimulation of the mouth. At birth, rats, cats and rabbits had long-latency reflexes which shortened with maturation. In the rat and rabbit, adult values are reached a day or so before they are known to ingest solid food. Only the guinea pig, which eats solids on day 1, had the adult latency at birth. The time course of the latency reduction in the rabbit appeared to have two phases. The first phase was rapid (1-2 days) and appeared to be largely of central origin. The second phase was slower and lasted for about 2 weeks.
通过电刺激口腔，在断奶前的大鼠、兔子、猫和豚鼠的二腹肌及其他下颌下肌肉中诱发反射活动。出生时，大鼠、猫和兔子具有长潜伏期反射，该反射会随着成熟而缩短。在大鼠和兔子中，在已知它们摄取固体食物前一天左右就达到了成年值。只有在出生第一天就吃固体食物的豚鼠，出生时就具有成年潜伏期。兔子潜伏期缩短的时间进程似乎有两个阶段。第一阶段很快（1 - 2天），似乎主要源于中枢。第二阶段较慢，持续约2周。
