The rat maternal behavior consists of different pup-caring activities, such as retrieving, licking, and crouching. Mothers also build a nest, consume more food, are more aggressive, and show less fear behavior than in other stages of the reproductive cycle. It has been reported that oxytocin (OT) and the milk-ejection pathway could be involved in modulating maternal behavior. The paraventricular nucleus (PVN) of the hypothalamus forms part of the milk-ejection pathway and is also the major source of OT release in the brain. Kainic acid (KA) lesions (0.5 microg/0.5 microl) in the PVN performed on day 2 after parturition, affected retrieving behavior in the mother rat and produced a decrease in pups' weight gain. Because KA destroys only cell bodies, the changes that we observed could be due to the local destruction of neurons, rather than that of the fibers of passage. No alteration was observed in other components of the pup-caring activities, food intake, aggressive behavior, and fear in the lesioned mothers.
