The ventrolateral periaqueductal gray is involved in the cardiovascular response evoked by L-glutamate microinjection into the lateral hypothalamus of anesthetized rats
(ELSEVIER IRELAND LTD, 2008)
Microinjection Of L-glutamate (L-glu: 1, 3, 10 and 30nmol/100nL) into the lateral hypothalamus (LH) caused dose-related depressor and bradycardiac responses. The cardiovascular response to L-glu stimulation of the LH was ...
NMDA and non-NMDA glutamate receptors in the paraventricular nucleus of the hypothalamus modulate different stages of hemorrhage-evoked cardiovascular responses in rats
(2016-04-21)
Here we report the involvement of N-Methyl-d-Aspartate (NMDA) and non-NMDA glutamate receptors from the paraventricular nucleus of the hypothalamus (PVN) in the mediation of cardiovascular changes observed during hemorrhage ...
NMDA receptors in the lateral hypothalamus have an inhibitory influence on the tachycardiac response to acute restraint stress in rats
(2013-08-01)
The aim of the present study was to investigate the role of the lateral hypothalamus (LH) and its local glutamatergic neurotransmission in the cardiovascular adjustments observed when rats are submitted to acute restraint ...

Papel dos receptores glutamatérgicos ionotrópicos do hipotálamo dorsomedial na regulação das respostas cardiovasculares e comportamental do quimiorreflexo
(Universidade Federal de Minas GeraisUFMG, 2012-07-10)
Studies from our laboratory (Queiroz et al., 2011) showed that bilateral microinjection of lidocaine into the DMH reduces the pressor response to chemoreflex. These studies also showed that the bilateral blockade of glutamate ...
N-Methyl-D-aspartate Glutamate Receptor Modulates Cardiovascular and Neuroendocrine Responses Evoked by Hemorrhagic Shock in Rats
(2021-01-01)
Here, we report the participation of N-methyl-D-aspartate (NMDA) glutamate receptor in the mediation of cardiovascular and circulating vasopressin responses evoked by a hemorrhagic stimulus. In addition, once NMDA receptor ...
Role of N-Methyl-D-Aspartate and Non-N-Methyl-D-Aspartate Receptors in the Cardiovascular Effects of L-Glutamate Microinjection Into the Hypothalamic Paraventricular Nucleus of Unanesthetized Rats
(WILEY-LISS, 2009)
We report on the cardiovascular effects of L-glutamate (L-glu) microinjection into the hypothalamic paraventricular nucleus (PVN) as well as the mechanisms involved in their mediation. L-glu microinjection into the PVN ...
N-Methyl-D-aspartate glutamate receptors in the hypothalamic paraventricular nucleus modulate cardiac component of the baroreflex in unanesthetized rats
(ELSEVIER IRELAND LTD, 2010)
In the present study, we investigated the role played by the hypothalamic paraventricular nucleus (PVN) in the modulation of cardiac baroreflex activity in unanesthetized rats. Bilateral microinjections of the nonselective ...
The expression of contextual fear conditioning involves activation of an NMDA receptor-nitric oxide pathway in the medial prefrontal cortex
(OXFORD UNIV PRESS INC, 2008)
The ventral portion of medial prefrontal cortex (vMPFC) is involved in contextual fear-conditioning expression in rats. In the present study, we investigated the role of local N-methyl-D-aspartic acid (NMDA) glutamate ...
