Post-stress analgesia in rats with partial amygdala lesions.
نویسنده
چکیده
The role of the dorsal basal and the central nuclei of the amygdala under two modes of foot-shock analgesia was studied in 45 Möll-Wistar rats. Four minutes of continuous foot-shock produced post-stress analgesia in control and in all lesioned rats, but 20 min of regularly intermittent foot-shock did not evoke analgesia in rats with central nucleus lesion. This result indicates different involvement of dorsal basal and central nuclei in processing of stressful stimuli.

Post-stress analgesia after lesions to the central nucleus of the amygdala in rats.
In two experiments the role of the central nucleus of the amygdala under two modes of foot-shock analgesia was studied in 39 male Möll-Wistar rats. In Experiment I a 4 min continuous foot-shock, dependent on neural mechanism was used as a stressor. Analgesia was produced by regularly intermitted 20 min of foot-shock action in Experiment II which evoke an opioid, humorally mediated mechanism. Th...
متن کاملAqueous extract of saffron administration along with amygdala deep brain stimulation promoted alleviation of symptoms in post-traumatic stress disorder (PTSD) in rats
Objective: Post-traumatic stress disorder (PTSD) as one of the most devastating kinds of anxiety disorders, is the consequence of a traumatic event. Crocus sativus L., commonly known as saffron have been traditionally used for treatment of stress and anxiety. In this study, we evaluated the effects of peripheral administration of saffron, along with deep brain stimulation (DBS) in a post-trauma...

Objective(s): Post-traumatic stress disorder (PTSD), one of the most devastating kinds of anxiety disorders, is the consequence of a traumatic event followed by intense fear. In rats with contextual fear conditioning (CFC), a model of PTSD caused by CFC (electrical foot shock chamber), deep brain stimulation (DBS) alleviates CFC abnormalities.Materials and Methods: Forty Male Wistar rats (220–2...
متن کاملOpioid Receptors of the Central Amygdala and Morphine-Induced Antinociception
The amygdala is a forebrain region, which is known as a modulator of pain sensation. The amygdala, particularly the central nucleus, has high concentrations of enkephalins relative to dynorphins and has high concentrations of opioid receptors. We here studied the role of central nuclei of amygdala in morphine antinociception. Methods: In this study, we used 130 male Wistar rats (200- 250g). Bil...
متن کاملRole of the amygdala in the coordination of behavioral, neuroendocrine, and prefrontal cortical monoamine responses to psychological stress in the rat.
Exposure to mild stress is known to activate dopamine (DA), serotonin (5-HT), and norepinephrine (NE) metabolism in the anteromedial prefrontal cortex (m-PFC). Neuroanatomical site(s) providing afferent control of the stress activation of the m-PFC monoaminergic systems is at present unknown. The present study used a conditioned stress model in which rats were trained to fear a substartle-thres...
