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), ...
Tonic modulation of anxiety-like behavior by corticotropin-releasing factor (CRF) type 1 receptor (CRF1) within the medial prefrontal cortex (mPFC) in male mice: Role of protein kinase A (PKA)
(Hormones And Behavior, 2014-07-01) [Artigo]
The medial prefrontal cortex (mPFC) and the neuropeptide corticotropin-releasing factor (CRF) have recently been receiving more attention from those interested in the neurobiology of anxiety. Here, we investigated the CRF ...
Increased corticosterone levels in mice subjected to the rat exposure test
(Hormones and Behavior, 2010-02-01) [Artigo]
In recent years, there has been a notable interest in studying prey-predator relationships to develop rodent-based models for the neurobehavioral aspects of stress and emotion. However, despite the growing use of transgenic ...
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 ...
