Chronic intermittent hypoxia impairs heart rate responses to AMPA and NMDA and induces loss of glutamate receptor neurons in nucleus ambiguous of F344 rats.

Chronic intermittent hypoxia (CIH), as occurs in sleep apnea, impairs baroreflex-mediated reductions in heart rate (HR) and enhances HR responses to electrical stimulation of vagal efferent. We tested the hypotheses that HR responses to activation of alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA) and N-methyl-D-aspartate (NMDA) receptors in the nucleus ambiguous (NA) are reduced i...

Postnatal expression of EAAC1 and glutamate receptor subunits in vestibular nuclear neurons responsive to vertical linear acceleration

Both glutamate receptors and transporters are known to be important in the postsynaptic regulation of glutamate neurotransmission. However, the maturation profile of glutamate transporter EAAC1 and glutamate receptor subunits (NR1, NR2A and NR2B; and GluR 1-4) in functionally activated saccule-related vestibular nuclear neurons of postnatal rats remains unclear. In the present study, conscious ...

Glutamate Receptors in Nucleus Accumbens Can Modulate Canabinoid-Induced Antinociception in Rat’s Basolateral Amygdala

Introduction: It has been shown that administration of WIN55,212-2, a cannabinoid receptor agonist, into the basolateral amygdala (BLA), dose-dependently increases the thermal latency to withdrawal in the tail-.ick test and decreases pain related behaviors in both phases of the formalin test. Recent human and animal imaging data suggest that the nucleus accumbens (NAc) is an important neural su...

The effect of glutaminergic system on cardiovascular regulation of rat

Introduction: The bed nucleus stria terminalis (BST) is a part of the limbic system, which plays a role in regulation of heart beat and blood circulation. It was recently shown that microinjection of L-glutamate in the BST elicits cardiovascular depressive, but the role of glutamate receptor subtypes has not been investigated yet. In this study, the role of glutamate receptor subgroups in regul...
