Avaliação do papel da amídala na antinocicepção induzida pelo medo : análises comportamental, imunoistoquímica e farmacológica
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Ciências Fisiológicas - PIPGCFCâmpus São Carlos, 2017-05-30)
Exposure of rodents to an open elevated plus maze (oEPM, an EPM with all four open arms) elicits antinociceptive responses, high level of plasma corticosterone and defensive behaviors. However, very little is known about ...
In utero exposure to air pollution lowers erythrocyte antioxidant defense and decreases weight in adult mice
(ELSEVIER SCIENCE BV, 2011)
In this study, we tested the influence of ambient air pollution on different phases of development of adult mice. With respect to adult weight, the animals that had spent their in utero period exposed to pollution showed ...
In utero exposure to air pollution lowers erythrocyte antioxidant defense and decreases weight in adult mice
(Elsevier B.V., 2011-09-01)
In this study, we tested the influence of ambient air pollution on different phases of development of adult mice. With respect to adult weight, the animals that had spent their in utero period exposed to pollution showed ...
GABA(A) receptor blockade in dorsomedial and ventromedial nuclei of the hypothalamus evokes panic-like elaborated defensive behaviour followed by innate fear-induced antinociception
(ELSEVIER SCIENCE BV, 2009)
Dysfunction in the hypothalamic GABAergic system has been implicated in panic syndrome in humans. Furthermore, several studies have implicated the hypothalamus in the elaboration of pain modulation. Panic-prone states are ...
Multiple stable states in a model based on predator-induced defenses
(2017)
A large variety of antipredator defenses are exhibited by plants, animals and microbes in nature. A deep understanding of the dynamic consequences of prey responses to predation risk is essential for building a comprehensive ...
Involvement of dorsal raphe nucleus and dorsal periaqueductal gray 5-HT receptors in the modulation of mouse defensive behaviors
(ELSEVIER SCIENCE BV, 2011)
Previous findings point to the involvement of the dorsal raphe nucleus (DRN) and dorsal periaqueductal gray (dPAG) serotonergic receptors in the mediation of defensive responses that are associated with specific subtypes ...
Evidence for the thalamic targets of the medial hypothalamic defensive system mediating emotional memory to predatory threats
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
Previous studies from our laboratory have documented that the medial hypothalamic defensive system is critically involved in processing actual and contextual predatory threats, and that the dorsal premammillary nucleus ...
Habits of Five Brazilian Snakes with Coral-snake Pattern, Including a Summary of Defensive Tactics
(1991-01-01)
Habitat, activity period, food, predators, and defensive behavior are briefly described for five species of snakes with coral-snake pattern, sympatric in southeastern Brazil: Micrurus frontalis, M. lemniscatus, Erythrolamprus ...
