Ventrolateral periaqueductal gray lesion attenuates nociception but does not change anxiety-like indices or fear-induced antinociception in mice
(Behavioural Brain Research, 2011-06-01) [Artigo]
The exposure of rodents to an open elevated plus-maze (oEPM: four open arms raised from the floor) elicits naloxone-insensitive antinociception. Midazolam infusion into the dorsal portion of the periaque-ductal gray (dPAG), ...
Anxiolytic-like effects of erythrinian alkaloids from erythrina suberosa
(Química Nova, 2011-01-01) [Artigo]
Two alkaloids, erysodine (1) and erysothrine (2) were isolated from the flowers of a Pakistani medicinal plant, Erythrina suberosa. These compounds were investigated for anxiolytic properties, and the results showed ...
Anxiogenic and antinociceptive effects induced by corticotropin-releasing factor (CRF) injections into the periaqueductal gray are modulated by CRF1 receptor in mice
(Hormones and Behavior, 2011-08-01) [Artigo]
Chemical or electrical stimulation of the dorsal portion of the midbrain periaqueductal gray (dPAG) produces anxiogenic and antinociceptive effects. In rats, chemical stimulation of dPAG by local infusion of the neuropeptide ...
Corticosterone does not change open elevated plus maze-induced antinociception in mice
(Hormones and Behavior, 2011-09-01) [Artigo]
It has been demonstrated that the exposure of rodents to the standard elevated plus-maze (sEPM: 2 open and 2 enclosed arms) elicits defensive behavioral reactions and antinociception and also activates the hypothalamo-pi ...
