Effects of direct periaqueductal grey administration of a cannabinoid receptor agonist on nociceptive and aversive responses in rats
(Elsevier, 2003-07-31)The analgesic potential of cannabinoids may be hampered by their ability to produce aversive emotion when administered systemically. We investigated the hypothesis that the midbrain periaqueductal grey (PAG) is a common ... -
Evidence for differential modulation of conditioned aversion and fear‐conditioned analgesia by CB1 receptors
(Wiley, 2004-07-15)Fear‐conditioned analgesia is an important survival response mediated by substrates controlling nociception and aversion. Cannabinoid1 (CB1) receptors play an important role in nociception and aversion. However, their role ... -
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. ... -
Chronic fluoxetine treatment attenuates stressor-induced changes in temperature, heart rate, and neuronal activation in the olfactory bulbectomised rat
(2007)The olfactory bulbectomized (OB) rat is a well characterized animal model that exhibits a number of behavioural and neurochemical changes that have relevance to clinical depression. Hyperactivity in the open field is the ... -
Endocannabinoid-mediated enhancement of fear-conditioned analgesia in rats: Opioid receptor dependency and molecular correlates
(International Association for the Study of Pain, 2008-12)The opioid and endocannabinoid systems mediate analgesia expressed upon re-exposure to a contextually aversive stimulus (fear-conditioned analgesia; FCA), and modulate the mitogen-activated protein kinase (MAPK) pathway. ... -
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 ... -
6-iodonordihydrocapsaicin
(2009)6-Iodonordihydrocapsaicin was first synthesized by Giovanni Appendino at the Department of Chemical, Food, Pharmaceutical and Pharmacological Sciences (DiSCAFF), Novara, Italy, while developing a series of halogenated ... -
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. ... -
Inhibition by Anandamide of 6-Hydroxydopamine-Induced Cell Death in PC12 Cells
(2010)6-hydroxydopamine (6-OHDA) is a selective neurotoxin that is widely used to investigate cell death and protective strategies in models of Parkinson's disease. Here, we investigated the effects of the endogenous cannabinoid, ... -
Enhanced nociceptive responding in two rat models of depression is associated with alterations in monoamine levels in discrete brain regions
(2010)Altered pain responding in depression is a widely recognized but poorly understood phenomenon The present study investigated nociceptive responding to acute (thermal and mechanical) and persistent (inflammatory) noxious ... -
Brain CB2 receptors: Implication for Neuropsychiatric disorders
(2010)Although previously thought of as the peripheral cannabinoid receptor, it is now accepted that the CB2 receptor is expressed in the central nervous system on microglia, astrocytes and subpopulations of neurons. Expression ... -
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 ... -
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) ... -
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 ... -
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 ... -
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, ... -
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 ...
