We determined the role of glutamate receptor activation in the rostral raphe pallidus (RPa) in mediating the sympathoexcitatory responses in HR, BAT SNA and RSNA following disinhibition of DMH neurons in urethane/chloralose anesthetized, artificially ventilated rats.

In alpha-chloralose-anesthetized rabbits, we determined the number of extracellular action potentials synaptically evoked by low (1 Hz)- or high-frequency vagal (3-20 Hz) or aortic depressor nerve (ADN) (6-80 Hz) stimulation and postsynaptically evoked by the ionotropic glutamate receptor agonist alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA).

16125857 Cerri M, Morrison SF: Activation of lateral hypothalamic neurons stimulates brown adipose tissue thermogenesis. Neuroscience. 2005;135(2):627-38.

To determine if activation of lateral hypothalamic area neurons influences sympathetically-regulated thermogenesis in brown adipose tissue, we microinjected bicuculline (120 pmol, 60 nl, unilateral) into the lateral hypothalamic area in urethane/chloralose-anesthetized, artificially-ventilated rats.
Subsequent microinjections of glycine (30 nmol, 60 nl) to inhibit local neurons in raphe pallidus or in dorsomedial hypothalamus or of glutamate receptor antagonists into dorsomedial hypothalamus promptly reversed the increases in brown adipose tissue sympathetic nerve activity, brown adipose tissue temperature and heart rate evoked by disinhibition of neurons in lateral hypothalamic area.

Experiments were performed in chloralose anesthetized, paralyzed and mechanically ventilated beagle dogs (n = 18), under hyperoxic, normocapnic, and normohydric conditions.
However, topical application or microinjection of AMPA/kainate subtype of glutamate receptor selective antagonists markedly reduced reflex increase in tracheal tone induced by (1) lung deflation, (2) stimulation of laryngeal cold receptors, and (3) activation of peripheral or central chemoreceptors.

We conclude that NTS A2a-purinoceptor activation evokes differential sympathetic responses similar to those observed during hemorrhage, whereas P2x-purinoceptor and glutamate-receptor activation evokes differential inhibition of sympathetic outputs similar to arterial baroreflex responses.
RSNA was recorded simultaneously with pre-ASNA or post-ASNA in chloralose-urethan-anesthetized male Sprague-Dawley rats.

7598871 Yamanaka T, Amano T, Sasa M, Matsunaga T: Prednisolone excitation of medial vestibular nucleus neurons in cats. Eur Arch Otorhinolaryngol. 1995;252(2):112-8.

An electrophysiological study was performed to determine whether prednisolone hydrochloride directly influenced neuronal activities of the medial vestibular nucleus (MVN) in alpha-chloralose-anesthetized cats.
Microiontophoretic GDEE, a non-selective glutamate receptor antagonist, inhibited glutamate- and rotation-induced neuronal discharges without affecting prednisolone-induced increases in neuronal responses of MVN.

16580142 Cerri M, Morrison SF: Corticotropin releasing factor increases in brown adipose tissue thermogenesis and heart rate through dorsomedial hypothalamus and medullary raphe pallidus. Neuroscience. 2006 Jun 30;140(2):711-21. Epub 2006 Mar 31.

To identify potential central pathways through which hypothalamic corticotropin releasing factor influences brown adipose tissue thermogenesis, corticotropin releasing factor was microinjected into the lateral ventricle (i.c.v.) or into hypothalamic sites while recording sympathetic outflow to brown adipose tissue, brown adipose tissue temperature, expired CO2, heart rate and arterial pressure in urethane/chloralose-anesthetized, artificially-ventilated rats.
These sympathetic responses to i.c.v. corticotropin releasing factor were eliminated by inhibition of neuronal activity in the dorsomedial hypothalamus or in the raphe pallidus, a putative site of sympathetic premotor neurons for brown adipose tissue, and were markedly reduced by microinjection of ionotropic glutamate receptor antagonists into the dorsomedial hypothalamus.

The present study was performed to examine the effects of a glucocorticoid, dexamethasone, on neuronal activity in the medial vestibular nucleus (MVN) to determine whether or not the drug acts directly on the MVN neuron using alpha-chloralose-anesthetized cats which were fixed in a stereotaxic instrument placed on a turn-table.
Each pipette was filled with dexamethasone phosphate (0.1 M), monosodium glutamate (1 M), glutamic acid diethylester (GDEE) (0.05 M: a non-selective glutamate receptor antagonist), CoCl2, (0.1 M: a non-specific calcium channel blocker), RU38486 (0.01 M: glucocorticoid receptor antagonist) or potassium canrenoate (0.1 M: a mineralo-cortical receptor antagonist).

Selective excitatory amino acid receptor antagonists acting on either N-methyl-D-aspartic acid (NMDA) or non-NMDA receptors were microinjected (30-50 nl) bilaterally into different subregions of the ventral respiratory group (VRG) of alpha-chloralose-urethane anaesthetized, vagotomized, paralysed and artificially ventilated rabbits.

We injected 10 nl (unilateral) of glutamate receptor antagonists or agonists into the region of the retrotrapezoid nucleus and measured the phrenic nerve and blood pressure responses.
The rats were chloralose-urethan anesthetized, paralyzed, vagotomized, and ventilated, and each injection location was verified anatomically.

In the present study, the possible involvement of the CVLM in mediating the depressor response elicited by the greater splanchnic nerve (GSPL) afferent stimulation was explored in rats anesthetized with urethane and alpha-chloralose.
Microinjection of lidocaine, and the glutamate receptor antagonists, kynurenic acid and 2-amino-7-phosphonolieptanoic acid, into the CVLM significantly blocked the depressor response induced by the GSPL afferent stimulation.

To test this possibility, the effects of focal pre-BotC hypoxia [induced by sodium cyanide (NaCN)] were examined before and after blockade of ionotropic EAA receptors [using kynurenic acid (KYN)] in this region in chloralose-anesthetized, vagotomized, mechanically ventilated cats.
