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 ...
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 ...
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 ...
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 ...
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 ...
Cognitive impairment in patients with chronic neuropathic or radicular pain: An interaction of pain and age
(Frontiers Media, 2017-06-13)
A growing body of empirical research has confirmed an association between chronic pain and cognitive dysfunction. The aim of the present study was to determine whether cognitive function is affected in patients with a ...
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 ...
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, ...
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, ...
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 ...
