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 ...
Gabaergic mechanisms of hypothalamic nuclei in the expression of conditioned fear
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
The amygdala, the dorsal periaqueductal gray (dPAG), and the media] hypothalamus have long been recognized to be a neural system responsible for the generation and elaboration of unconditioned fear in the brain. It is also ...
Effects of reversible inactivation of the dorsomedial hypothalamus on panic- and anxiety-related responses in rats
(Associação Brasileira de Divulgação Científica, 2010-09-01)
The medial hypothalamus is part of a neurobiological substrate controlling defensive behavior. It has been shown that a hypothalamic nucleus, the dorsomedial hypothalamus (DMH), is involved in the regulation of escape, a ...

Dorsomedial hypothalamus CRF type 1 receptors selectively modulate inhibitory avoidance responses in the elevated T-maze
(Elsevier B.V., 2014-09-01)
Corticotropin-releasing factor (CRF) plays a critical role in the mediation of physiological and behavioral responses to stressors. in the present study, we investigated the role played by the CRF system within the dorsomedial ...
Faster gastric emptying of a liquid meal in rats after hypothalamic dorsomedial nucleus lesion
(Associação Brasileira de Divulgação Científica, 1997)
Participação do sistema endocanabinoide do hipotálamo dorsomedial emeventos aversivos
(Universidade Federal de Minas GeraisUFMG, 2016-04-01)
The dorsomedial hypothalamus (DMH) is an important integrative nucleus for behavioral, endocrine and autonomic responses. The stimulation of DMH by excitatory amino acids, such as glutamate, promotes defensive responses ...
Mapping of somatostatin-28 (1-12) in the alpaca diencephalon
(Elsevier, 2011)
Using an immunocytochemical technique, we report for the first time the distribution of immunoreactive cell bodies and fibers containing somatostatin-28 (1-12) in the alpaca diencephalon. Somatostatin-28 (1-12)-immunoreactive ...
Co-Expression of Leptin and Oestrogen Receptors in the Preoptic-Hypothalamic Area
(WILEY-BLACKWELL, 2010)
The interaction between the reproductive axis and energy balance suggests that leptin acts as a possible mediator. This hormone acts in the regulation of metabolism, feeding behaviour and reproduction. Animals homozygous ...
