Validation of an air-puff passive-avoidance paradigm for assessment of aversive learning and memory in rat models of chronic pain
(Elsevier, 2011-11)Chronic pain is associated with cognitive deficits. Considerable overlap in brain regions involved in pain and aversion suggests that aversive learning and memory may be affected during chronic pain. Passive-avoidance ... -
Validation of an air-puff passive-avoidance paradigm for assessment of aversive learning and memory in rat models of chronic pain
(2012)Chronic pain is associated with cognitive deficits. Considerable overlap in brain regions involved in pain and aversion suggests that aversive learning and memory may be affected during chronic pain. Passive-avoidance ... -
Behavioural, neurochemical and neuroendocrine effects of the endogenous beta-carboline harmane in fear-conditioned rats
(2012)The putative endogenous imidazoline binding site ligand harmane enhances neuronal activation in response to psychological stress and alters behaviour in animal models of anxiety and antidepressant efficacy. However, the ... -
The endocannabinoid system and emotional processing: pathophysiology and therapeutic potential.
(SAGE, 2012-01)Although the pharmacological and medicinal properties of the plant Cannabis sativa have long been known and appreciated, the discovery of the endocannabinoid system began with the isolation of [delta]9-tetrahydrocannabinol ... -
Evidence for a role of GABAergic and glutamatergic signalling in the basolateral amygdala in endocannabinoid-mediated fear-conditioned analgesia in rats
(Elsevier, 2012-12-31)The basolateral amygdala (BLA) is a key substrate facilitating the expression of fear-conditioned analgesia (FCA). However, the neurochemical mechanisms in the BLA which mediate this potent suppression of pain responding ... -
Pharmacological inhibition of monoacylglycerol lipase attenuates LPS-induced increases in cytokine expression in the rat frontal cortex and plasma: differential mechanisms of action
(2013)Background and purpose: This study determined the effect of JZL184, a selective inhibitor of monoacylglycerol lipase (MAGL), the enzyme which preferentially catabolises the endocannabinoid 2-arachidonoyl glycerol (2-AG), ... -
Impaired endocannabinoid signalling in the rostral ventromedial medulla underpins genotype-dependent hyper-responsivity to noxious stimuli
(International Association for the Study of Pain, 2014-01)Pain is both a sensory and an emotional experience, and is subject to modulation by a number of factors including genetic background modulating stress/affect. The Wistar-Kyoto (WKY) rat exhibits a stress-hyper-responsive ... -
Cognition and pain
(Lippincott, Williams & Wilkins, 2014-06)Purpose of reviewPain and cognition share common neural substrates and are known to interact reciprocally. This has implications for treatment and management of pain conditions; pain can negatively affect cognitive ... -
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 ... -
Involvement of the endocannabinoid system in attentional modulation of nociceptive behaviour in rats
(Wiley, 2014-11-15)BackgroundDistraction is used clinically to relieve and manage pain. It is hypothesized that pain demands attention and that exposure to another attention-demanding stimulus causes withdrawal of attention away from painful ... -
Supraspinal Transient Receptor Potential Subfamily V Member 1 (TRPV1) in pain and psychiatric disorders
(Karger, 2015)The transient receptor potential subfamily V member 1 (TRPV1) belongs to the diverse transient receptor potential (TRP) family of cation channels. It was first characterized in primary afferent fibres as a receptor for ... -
Development and characterization of a novel, anatomically relevant rat model of acute postoperative pain
(Elsevier, 2015-01-30)Acute postoperative pain remains a significant health care issue. Development of anatomically relevant animal models of postoperative pain, with improved predictive validity, would advance understanding of postoperative ... -
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 ... -
Characterization of the affective component of acute postoperative pain associated with a novel rat model of inguinal hernia repair pain
(Wiley, 2015-12-10)Aims: Acute postoperative pain remains a significant healthcare issue. Historically, the assessment of postoperative pain in rodents has relied on evoked withdrawal or reflexive measures. Using a recently developed, ... -
Impaired recognition memory and cognitive flexibility in the rat L5-L6 spinal nerve ligation model of neuropathic pain
(De Gruyter, 2016-01-01)Background and aims: Although neuropathic pain is known to negatively affect cognition, the neural mechanisms involved are poorly understood. Chronic pain is associated with changes in synaptic plasticity in the brain which ... -
Impaired cued and spatial learning performance and altered cannabinoid CB1 receptor functionality in the substantia nigra in a rat model of diabetic neuropathy
(Elsevier, 2016-01-13)Diabetes, and associated diabetic neuropathic pain, impact negatively on cognitive function. However, the underlying mechanisms remain poorly understood. This study investigated neuropathic pain-related behaviour and ... -
Genotype-dependent responsivity to inflammatory pain: A role for TRPV1 in the periaqueductal grey
(Elsevier, 2016-08-09)Negative affective state has a significant impact on pain, and genetic background is an important moderating influence on this interaction. The Wistar-Kyoto (WKY) inbred rat strain exhibits a stress-hyperresponsive, ... -
Central CB2 receptors in inflammation-driven neurodegeneration: dysregulation and therapeutic potential
(Medknow Publications, 2016-10-19)In recent times there has been an intensification of interest in the pathological role of neuroinflammation in neurodegenerative disease. Neuroprotective strategies to slow, halt or reverse neurodegeneration have not proven ... -
N-palmitoylethanolamide in the anterior cingulate cortex attenuates inflammatory pain behaviour indirectly via a CB1 receptor-mediated mechanism
(Lippincott, Williams & Wilkins, 2016-12)The neural substrates and mechanisms mediating the antinociceptive effects of the endogenous bioactive lipid, N-palmitoylethanolamide (PEA), require further investigation. We investigated the effects of exogenous PEA ... -
Characterisation of peroxisome proliferator-activated receptor signalling in the midbrain periaqueductal grey of rats genetically prone to heightened stress, negative affect and hyperalgesia
(Elsevier, 2016-12-01)The stress-hyperresponsive Wistar-Kyoto (WRY) rat strain exhibits a hyperalgesic phenotype and is a useful genetic model for studying stress-pain interactions. Peroxisome proliferator-activated receptor (PPAR) signalling ...
