Adolescent place attachment, social capital, and perceived safety: a comparison of 13 countries.
(Springer, 2009-06-17)In adolescence, children become increasingly independent and autonomous, and spend more time in neighborhood settings away from home. During mid-to-late adolescence, youth often become more critical about the place they ... -
Emotional eating: feeding and fearing feelings - what psychologists need to know
(The Psychological Society of Ireland, 2017-06)This article reviews the psychological theories of emotional eating and introduces to a little known model, Affect Phobia, which combines both learning and psychodynamic theory -
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 ... -
Investigating the role of the endogenous cannabinoid system in emotional modulation of pain: neurochemical and molecular mechanisms
(2012-03-24)Abstract Pain represents a major unmet clinical need and affects a large number of individuals worldwide. The modulation of pain by cognitive and emotional factors is now widely recognised. Increased understanding of the ... -
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 ... -
Regulation of fear, anxiety and cognition in the presence or absence of pain by peroxisome proliferator-activated receptors
(NUI Galway, 2019-06-07)Fear/anxiety and pain modulate one another reciprocally, but the neurobiological mechanisms that underlie this interaction are not completely understood. Fear-conditioned analgesia (FCA) is pain suppression upon exposure ... -
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 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 ... -
The role of the endocannabinoid system in the emotional modulation of pain
(NUI Galway, 2018-09-06)Fear-conditioned analgesia (FCA) is the robust suppression of pain that occurs upon reexposure to a context previously paired with an aversive stimulus. FCA is mediated by activation of the descending inhibitory pain ... -
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 ...
