The role of perioral somatosensory stimulation from pups in maternal behavior was investigated in lactating Long-Evans rats (Rattus norvegicus) during early lactation by local anesthesia of the mystacial pads with lidocaine, which blocks conduction in the infraorbital nerve. It was concluded that (1) acute perioral anesthesia markedly inhibited pup retrieval when the subjects had no formal pretreatment retrieval experience. Further, these dams displayed little tolerance to the lidocaine treatment when they were tested repeatedly. (2) The severity of the effects of perioral anesthesia on retrieval was dependent upon prior experience and the testing situation. Following pretreatment retrieval experience, and in a test cage with dark and light compartments which provided a strong incentive to retrieve, 80% of lidocaine-injected dams did retrieve. However, retrieval efficiency was impaired by perioral anesthesia, largely due to increased time in contact with pups prior to each retrieval and to increased carrying time. (3) Perioral anesthesia also inhibited pup licking, but not self-grooming, suggesting that the former, but not the latter, is largely under peripheral stimulus control and that deficits in maternal oral activities cannot be due to impairment of mouth opening and use. (4) The onset of nursing behavior was delayed until after the recovery of snout sensations and retrieval. This suggests that a maternal behavior not directly involving the mouth is nonetheless dependent upon the dam's receipt of perioral tactile input from pups.
