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. Long-term social recognition memory in adult male rats: factor analysis of the social and non-social behaviors
A modified version of the intruder-resident paradigm was used to investigate if social recognition memory lasts at least 24 h. One hundred and forty-six adult male Wistar rats were used. Independent groups of rats were exposed to an intruder for 0.083, 0.5, 2, 24, or 168 h and tested 24 h after the first encounter with the familiar or a different conspecific

3. Analyses of hypothalamic systems involved in the organization of intra-specific defense. / Análise de sistemas hipotalâmicos envolvidos na organização da defesa intraespecífica.
Etologicamente, os animais expressam repostas de medo frente a um predador ou a um co-especifico e a organização neural de respostas defensivas intraespecíficas são pouco conhecidas. Assim, o objetivo deste trabalho foi estudar o papel hipotalâmico na organização da defesa intraespecífica. Observamos que o núcleo pré-mamilar dorsal do hipotálamo t

4. Estudo neuroquímico do núcleo pré-mamilar ventral nos animais submissos durante os encontros agonísticos sociais. / Neurochemic study of the premammillary ventralis nucleus on submissive animals during social agonistic encounters.
Aggressive behavior occurs when the interests of one or more individuals conflict. Territory is one of these interests, and the resident intruder paradigm is widely used to observe the expression of social agonistic behaviors. The dominance behavior has been studied under several views and it was shown that it can be raised by the presence of the female, its

5. Efeito de um complexo homeopático no desempenho e no comportamento de camundongos sob estresse agudo / Effect of a homeopatic complex on the performance and behavior of mice under acute stress
To evaluate the effect of homeopathic commercial complex (Convert H) on the performance and behavior of mice (Mus musculus) submitted to acute stress, two colonies were used: a Colony Bioterio (animals that did not receive the product) and Colony Convert H (animals from mice receiving the product for 16 generations). The animals were randomly assigned into f

6. Dynamic neuromodulation of aggression by vasotocin: influence of social context and social phenotype in territorial songbirds
The homologous neuropeptides vasotocin (VT) and vasopressin (VP) influence agonistic behaviours across many taxa, but peptide–behaviour relationships are complex and purportedly species-specific. Putative species-specific effects in songbirds are confounded with context, however, such that territorial species have been tested only in resident–intruder pa
