Locomotor and anti-immobility effects of buprenorphine in combination with the opioid receptor modulator samidorphan in rats
(Elsevier, 2018-12-13)Modulation of the opioid system has re-emerged as a potential therapeutic avenue for treating depression, with efficacy of a fixed-dose combination of buprenorphine (BUP), a partial mu-opioid receptor (MOR) agonist and ... -
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 ... -
Modulation of stress by imidazoline binding sites: Implications for psychiatric disorders
(Taylor & Francis, 2009-07-07)In this review, we present evidence for the involvement of imidazoline binding sites (IBS) in modulating responses to stress, through central control of monoaminergic and hypothalamo-pituitary-adrenal (HPA) axis activity. ... -
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 ... -
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 ... -
Pharmacological blockade of PPAR isoforms increases conditioned fear responding in the presence of nociceptive tone
(MDPI, 2020-02-24)Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors with three isoforms (PPAR¿, PPARß/¿, PPAR¿) and can regulate pain, anxiety, and cognition. However, their role in conditioned fear and pain-fear ... -
Pharmacological inhibition of endocannabinoid degradation modulates the expression of inflammatory mediators in the hypothalamus following an immunological stressor
(Elsevier, 2011-09)The endocannabinoid system is an important regulator of the nervous, neuroendocrine, and immune systems, thus representing a novel therapeutic target for stress-related neuroinflammatory and psychiatric disorders. However, ... -
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), ... -
PPARs and pain
(Wiley, 2018-04-21)Chronic pain is a common cause of disability worldwide and remains a global health and socio-economic challenge. Current analgesics are either ineffective in a significant proportion of patients with chronic pain or ... -
The prefrontal cortical endocannabinoid system modulates fear–pain interactions in a subregion‐specific manner
(Wiley, 2018-05-30)Background and Purpose The emotional processing and coordination of top‐down responses to noxious and conditioned aversive stimuli involves the medial prefrontal cortex (mPFC). Evidence suggests that subregions of the ... -
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 ... -
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 ... -
A role for viral infections in Parkinson's etiology?
(Portland Press, 2018-04-16)Despite over 200 years since its first description by James Parkinson, the cause(s) of most cases of Parkinson’s disease (PD) are yet to be elucidated. The disparity between the current understanding of PD symptomology and ... -
The role of the brain's endocannabinoid system in pain and its modulation by stress
(Elsevier, 2015-11-06)Stress has a complex, bidirectional modulatory influence on pain. Stress may either reduce (stress-induced analgesia) or exacerbate (stress-induced hyperalgesia) pain depending on the nature, duration, and intensity of the ... -
Stress-induced analgesia.
(Butler, R. K. & Finn, D.P. (2009). Stress-induced analgesia. Progress in Neurobiology, 88, 184-202., 2009)For over 30 years, scientists have been investigating the phenomenon of pain suppression upon exposure to unconditioned or conditioned stressful stimuli, commonly known as stress-induced analgesia. These studies have ... -
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 ... -
Supraspinal modulation of pain by cannabinoids: the role of GABA and glutamate
(2007)Recent physiological, pharmacological and anatomical studies provide evidence that one of the main roles of the endocannabinoid system in the brain is the regulation of ¿-aminobutyric acid (GABA) and glutamate release. ... -
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 ... -

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 ...
