1. Effects of REM sleep restriction during pregnancy on rodent maternal behavior
Objective: To evaluate the effects of sleep restriction during pregnancy on maternal care and maternal aggression in a rodent model. Methods: Twenty-three female Wistar rats were assigned to one of two groups: control (n=12) or sleep restriction (n=11) during the entire pregnancy. At the fifth postpartum day, the animals were subjected to the resident-intr

2. Fos expression in the prefrontal cortex and mesencephalic dorsal raphe nucleus in lactating rats after social instigation
Females are often less aggressive than males, but they exhibit high levels of agonistic behavior against an intruder in the area of the nest during lactation. This behavior is referred to as maternal aggression. In rats, maternal aggressive behavior occurs more often from postpartum day 3 (PPD 3) to PPD 12. Social instigation is an experimental protocol used

3. Papel do hipotálamo ventromedial e da parte tuberal do hipotálamo lateral no comportamento de agressão maternal. / Role of the ventromedial hypothalamus and tuberalis part of the lateral hypothalamus in maternal behavior aggression.
O comportamento agressivo maternal é desenvolvido por ratas lactantes com o intuito de preservar a vida de sua prole. Nesse estudo demonstramos que a Área Hipotalâmica de Ataque (HAA), particularmente a porção ventrolateral do núcleo ventromedial (VMHvl) e a parte tuberal do hipotálamo lateral (LHAtu), apresentam um papel crítico para a expressão do

4. Estresse pré-natal e suas repercussões sobre o cuidado maternal e comportamento de ratos a curto e a longo prazo
In humans and rodents, stress during pregnancy has produced offspring with high levels of anxiety, impaired learning and memory, changes in maternal care and social behavior deficits. Most prenatal stress protocols have attributed their results to the vulnerability of the intrauterine period. However, studies show that the consequences caused by this action

5. Effect of social instigation and aggressive behavior on hormone levels of lactating dams and adult male Wistar rats
Among rodents, maternal aggression in the postpartum period represents a species-typical adaptation, but when aggressive behavior increases beyond this adaptive level, it can represent a model of excessive aggression. This study assessed the neuroendocrine response of lactating rats and socially instigated male rats. The aim of the present study was to asses

6. Effect of 5-HT1B receptor agonists injected into the prefrontal cortex on maternal aggression in rats
Serotonin (5-HT1B) receptors play an essential role in the inhibition of aggressive behavior in rodents. CP-94,253, a 5-HT1B receptor agonist, can reduce aggression in male mice when administered directly into the ventro-orbitofrontal (VO) prefrontal cortex (PFC). The objective of the current study was to assess the effects of two selective 5-HT1B receptor a

7. Pup age and aggressive behavior in lactating rats
High levels of aggressive behaviors against intruders in the nest area are displayed by female rats during the first 10 days after delivery, declining thereafter to very low levels, even though lactation continues. Cross-fostering experiments were undertaken to test the hypothesis that pup age may affect aggression in lactating rats. The behavior of females

10. Maternal aggression in Wistar rats: effect of 5-HT2A/2C receptor agonist and antagonist microinjected into the dorsal periaqueductal gray matter and medial septum
The objective of the present study was to assess the role of the 5-HT2A/2C receptor at two specific brain sites, i.e., the dorsal periaqueductal gray matter (DPAG) and the medial septal (MS) area, in maternal aggressive behavior after the microinjection of either a 5-HT2A/2C receptor agonist or antagonist. Female Wistar rats were microinjected on the 7th pos

12. Maternal yolk androgens stimulate territorial behaviour in black-headed gull chicks
Avian eggs contain substantial amounts of maternal androgens. The concentrations of these yolk androgens are affected by the maternal environment, such as the level of social competition, parasite exposure or food conditions. Since yolk androgens have been shown to affect a wide array of offspring traits, they may adjust the chicks to the expected post-hatch
