Role of NMDA receptors in the syndrome of behavioral changes produced by predator stressJacqueline Blundell
Department of Psychology, Memorial University, St. John's, NF, Canada
Physiol Behav 86:233-43. 2005..Components of this syndrome of behavioral changes likely depend on changes in separable neural substrates initiated in part by NMDA receptors as well as by other neurochemical means...- A comparison of activation patterns of cells in selected prefrontal cortical and amygdala areas of rats which are more or less anxious in response to predator exposure or submersion stressRobert Adamec
Memorial University, St John s, Newfoundland, Canada
Physiol Behav 105:628-38. 2012..The data suggest that preclinical markers of vulnerability/resilience in a given stress paradigm are at best suggestive, and translational value must ultimately be confirmed in humans... - Lasting anxiogenic effects of feline predator stress in mice: sex differences in vulnerability to stress and predicting severity of anxiogenic response from the stress experienceRobert Adamec
Department of Psychology, Memorial University, 232 Elizabeth Avenue, St John s, NF, Canada, A1B 3X9
Physiol Behav 88:12-29. 2006..Moreover, stressors had no lasting effects on sugar solution consumption. Implications of these findings for modeling PTSD and using transgenic strains of mice to study lasting effects of stress on affect are discussed... - Long lasting effects of predator stress on pCREB expression in brain regions involved in fearful and anxious behaviorRobert Adamec
Department of Psychology, Memorial University, 232 Elizabeth Avenue St John s, NL, Canada
Behav Brain Res 221:118-33. 2011..Identification of these changes may aid in understanding the neural mechanisms underlying acquired anxiety disorders such as PTSD... - Elevated pCREB in the PAG after exposure to the elevated plus maze in rats previously exposed to a catJacqueline Blundell
Department of Psychology, Memorial University of Newfoundland and Labrador, St John s, Nfld, Canada A1B 3X9
Behav Brain Res 175:285-95. 2006..If what happens in animals also occurs in humans, the findings of this study suggest that neural mechanisms of prior traumatic stress may interact with subsequent stress to reinforce psychopathology... - Activation patterns of cells in selected brain stem nuclei of more and less stress responsive rats in two animal models of PTSD - predator exposure and submersion stressRobert Adamec
Dept of Psychology, Memorial University, St John s, Newfoundland, Canada
Neuropharmacology 62:725-36. 2012..This article is part of a Special Issue entitled 'Post-Traumatic Stress Disorder'... - Vulnerability to lasting anxiogenic effects of brief exposure to predator stimuli: sex, serotonin and other factors-relevance to PTSDRobert Adamec

Behav Brain Res 170:126-40. 2006..Findings suggest a role for abnormalities in 5-HT transmission in vulnerability to some of the lasting anxiogenic effects of species relevant stressors and possibly in vulnerability to PTSD... - Dendritic morphology of amygdala and hippocampal neurons in more and less predator stress responsive rats and more and less spontaneously anxious handled controlsRobert Adamec
Memorial University, St John s, Newfoundland, Canada, A1B 3X9
Behav Brain Res 226:133-46. 2012..Significance of findings for animal models of anxiety and hyperarousal comorbidities of PTSD are discussed... - Anxiolytic effects of kindling role of anatomical location of the kindling electrode in response to kindling of the right basolateral amygdalaRobert Adamec

Dept of Psychology, Memorial University, 232 Elizabeth Ave, St John s, NL, Canada
Neurosci Biobehav Rev 29:1225-41. 2005..Findings will be discussed within the context of what is known about neural substrates activated by predator odor... - Role of NMDA receptors in the lateralized potentiation of amygdala afferent and efferent neural transmission produced by predator stressRobert Adamec
Department of Psychology, Memorial University, St John s, NF, Canada
Physiol Behav 86:75-91. 2005..In contrast, a lateral ACE-PAG pathway is implicated in mediating changes in startle habituation. Finally, consistent with cat and human studies, the right hemisphere appears particularly important in long term response to stress... - Phosphorylated cyclic AMP response element binding protein expression induced in the periaqueductal gray by predator stress: its relationship to the stress experience, behavior and limbic neural plasticityRobert E Adamec
