Altered neuropathic pain behaviour in a rat model of depression is associated with changes in inflammatory gene expression in the amygdala
(Wiley, 2013-08-29)
The association between chronic pain and depression is widely recognized, the comorbidity of which leads to a heavier disease burden, increased disability and poor treatment response. This study examined nociceptive ...
The effect of pain on cognitive function: a review of clinical and preclinical research.
(2011)
Cognitive impairment is commonly associated with the pain experience. This impairment represents a major obstacle to daily activities and rehabilitation, especially in the chronic pain population. Here we review clinical ...
Lived experiences of fibromyalgia
(RCN Publishing, 2015-02-10)
Martina Diviney and Maura Dowling explain why this chronic illness can take a long time to diagnose and how assessment tools can be used to speed up the process
This phenomenological study explored the lived experience ...
A role for the ventral hippocampal endocannabinoid system in fear-conditioned analgesia and fear responding in the presence of nociceptive tone in rats.
(Elsevier, 2011-08)
The endogenous cannabinoid (endocannabinoid) system plays an important role in fear-conditioned analgesia (FCA) and expression and extinction of conditioned fear. The hippocampus has an established role in both pain and ...
The endocannabinoid system in the rat dorsolateral periaqueductal grey mediates fear-conditioned analgesia and controls fear expression in the presence of nocicpetive tone
(Wiley, 2011)
Background and purpose: Endocannabinoids in the midbrain periaqueductal grey (PAG) are involved in modulating nociception and unconditioned stress-induced analgesia, however, their role in fear-conditioned analgesia (FCA) ...
Fear-induced suppression of nociceptive behaviour and activation of signal transduction molecules in the rat periaqueductal grey: role of fatty acid amide hydrolase.
(Sage, 2011-09-17)
The endocannabinoid system regulates nociception and aversion and mediates fear-conditioned analgesia (FCA). We investigated the effects of the fatty acid amide hydrolase (FAAH) inhibitor URB597, which inhibits the catabolism ...
Molecular and electrophysiological changes in the prefrontal cortex-amygdala-dorsal periaqueductal grey pathway during persistent pain state and fear-conditioned analgesia
(Elsevier, 2011-10)
Fear-conditioned analgesia (FCA) is the reduction in pain responding which is expressed upon re-exposure to a context previously paired with an aversive stimulus. Projections along the prefrontal cortex (PFC)¿amygdala¿dorsal ...
Modulation of Conditioned Fear, Fear-Conditioned Analgesia, and Brain Regional C-Fos Expression Following Administration of Muscimol into the Rat Basolateral Amygdala
(Elsevier, 2011-04)
Evidence suggests that gamma-aminobutyric acid (GABA) signalling in the basolateral amygdala (BLA) is involved in pain, fear, and fear-conditioned analgesia (FCA). In this study, we investigated the effects of intra-BLA ...
Repeated forced swim stress differentially affects formalin-evoked nociceptive behaviour and the endocannabinoid system in stress normo-responsive and stress hyper-responsive rat strains
(Elsevier, 2015-05-16)
Repeated exposure to a homotypic stressor such as forced swimming enhances nociceptive responding in rats. However, the influence of genetic background on this stress-induced hyperalgesia is poorly understood. The aim of ...
Stress-induced hyperalgesia
(Elsevier, 2014-07-08)
The importance of the modulation of pain by emotion is now widely recognised. In particular, stress and anxiety, depending on their nature, duration and intensity, can exert potent, but complex, modulatory influences ...
