Cutaneous desensitization of the upper, rostral snout by bilateral section of the infraorbital nerves in lactating Norway rat dams markedly, but transiently, disrupted retrieval and licking of pups, nursing behavior, and fighting with a strange male intruder. Removal of the mystacial vibrissae, which provide major inputs to the infraorbital nerves, or cutaneous desensitization of the chin by bilateral sectioning of the mental nerves did not disrupt these behaviors. However, cutaneous… CONTINUE READING
