Effects of intra-PAG infusion of ovine CRF on defensive behaviors in Swiss-Webster mice
(Elsevier B.V., 2007-01-25)
The midbrain dorsal periaqueductal gray (DPAG) is part of the brain defensive system involved in active defense reactions to threatening stimuli. Corticotrophin releasing factor (CRF) is a peptidergic neurotransmitter that ...
Effects of intra-PAG infusion of ovine CRF on defensive behaviors in Swiss-Webster mice
(Elsevier B.V., 2007-01-25)
The midbrain dorsal periaqueductal gray (DPAG) is part of the brain defensive system involved in active defense reactions to threatening stimuli. Corticotrophin releasing factor (CRF) is a peptidergic neurotransmitter that ...
Intra-dorsal periaqueductal gray administration of cannabidiol blocks panic-like response by activating 5-HT1A receptors
(ELSEVIER SCIENCE BV, 2010)
Activation of 5-HT1A receptors in the dorsal periaqueductal gray (dPAG) impairs escape behavior, suggesting a panicolytic-like effect. Cannabidiol (CBD), a major non-psychotomimetic compound present in Cannabis sativa, ...
Paraventricular nucleus mediates pressor response to noradrenaline injection into the dorsal periaqueductal gray area
(ELSEVIER SCIENCE BV, 2009)
The dorsal periaqueductal gray area (dPAG) is involved in cardiovascular modulation. In a previous study, we reported that noradrenaline (NA) microinjection into the dPAG of rats caused pressor response that was mediated ...
Anxiolytic-like effect of noradrenaline microinjection into the dorsal periaqueductal gray of rats
(LIPPINCOTT WILLIAMS & WILKINS, 2009)
The brain noradrenergic system has been implicated in the expression of defensive behaviors elicited by acute stress. The dorsal periaqueductal gray area (dPAG) is a key structure involved in the behavioral and cardiovascular ...
The diagonal band of Broca is involved in the pressor pathway activated by noradrenaline microinjected into the periaqueductal gray area of rats
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Aims: The dorsal periaqueductal gray area (dPAG) is involved in cardiovascular modulation. Previously, we reported that noradrenaline (NA) microinjection into the dPAG caused a pressor response that was mediated by vasopressin ...
Facilitation of 5-HT(1A)-mediated neurotransmission in dorsal periaqueductal grey matter accounts for the panicolytic-like effect of chronic fluoxetine
(CAMBRIDGE UNIV PRESS, 2010)
Chronic administration of antidepressants such as fluoxetine and imipramine increases the responsiveness of 5-HT(1A) receptors in dorsal periaqueductal grey matter (DPAG), a midbrain area consistently implicated in the ...
Direct determination of parameters of activation of the unimolecular reaction of glutaraldehyde diperoxide by gas chromatography
(Gupta Publications, 2020-02)
Gas phase thermolysis reaction of glutaraldehyde acid diperoxide (3,6-dibutanoic -1,2,4,5-tetroxane,DPAG) was performed in an injection chamber of a gas chromatograph as a constant time thermal flow reactor, has been applied ...
Alprazolam potentiates the antiaversive effect induced by the activation of 5-HT(1A) and 5-HT(2A) receptors in the rat dorsal periaqueductal gray
(SPRINGER, 2008)
Rationale Serotonin in the dorsal periaqueductal gray (DPAG) through the activation of 5-HT(1A) and 5-HT(2A) receptors inhibits escape, a defensive behavior associated with panic attacks. Long-term treatment with antipanic ...
Regulation of conditioned and unconditioned fear in rats by 5-HT1A receptors in the dorsal periaqueductal gray
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Studies on the involvement of 5-HT1-mediated mechanisms in the dorsal periaqueductal gray (dPAG) of animals with past stressful experiences have not been conducted so far. We investigated the role of 5-HT1 receptors in the ...
