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 ...
Panic-like defensive behavior but not fear-induced antinociception is differently organized by dorsomedial and posterior hypothalamic nuclei of Rattus norvegicus (Rodentia, Muridae)
(Associação Brasileira de Divulgação Científica, 2012)
The hypothalamus is a forebrain structure critically involved in the organization of defensive responses to aversive stimuli. Gamma-aminobutyric acid (GABA)ergic dysfunction in dorsomedial and posterior hypothalamic nuclei ...
NMDA and AMPA/Kainate Glutamatergic Receptors in the Prelimbic Medial Prefrontal Cortex Modulate the Elaborated Defensive Behavior and Innate Fear-Induced Antinociception Elicited by GABA(A) Receptor Blockade in the Medial Hypothalamus
(Oxford Univ Press Inc, 2014-06-01)
The aim of the present study was to investigate the involvement of N-methyl-d-aspartate (NMDA) and amino-3-hydroxy-5-methyl-isoxazole-4-proprionate (AMPA)/kainate receptors of the prelimbic (PL) division of the medial ...
Influência do ambiente aversivo na resposta nociceptiva de ratos : um estudo sobre o papel de receptores opióides e canabinóides
(Universidade Federal de São CarlosBRUFSCarPrograma Interinstitucional de Pós-Graduação em Ciências Fisiológicas - PIPGCF, 2009-12-11)
In innate or learned threatening situations, animals display a set of defensive behaviors specie-specific such as autonomic alterations, flight, fight and antinociception. Exposure of mice to open elevated plus-maze (oEPM: ...
Microinjeção de midazolam no hipotálamo posterior não reverte a antinocicepção induzida pelo labirinto em cruz elevado aberto em ratas
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM BIOLOGIA ESTRUTURAL E FUNCIONAL, 2018-12-12)
Animals exposure to threatening situations (innate or learned nature) induces a set of
species-specific defense behaviors, among them, antinociception. It has been shown that
rodents exposed to the open elevated plus ...
Caracterización electroencefalográfica de la ruta subcortical colículo superior – amígdala, vía tálamo, durante la asociación de estímulos condicionado e incondicionado: Evaluación de la integración sensorial multimodal en colículo superior y amígdala
(Bogotá - Medicina - Maestría en NeurocienciasUniversidad Nacional de Colombia - Sede Bogotá, 2020-08-11)
Superior Colliculus (SC) is a crucial structure for vertebrate survival given its role in organizing behavioral responses to unexpected visual stimuli. SC is anatomically and functionally connected with aversive stimuli ...
