Neurotoxic lesions of the dorsal and ventral hippocampus impair acquisition and expression of trace-conditioned fear-potentiated startle in ratsMehul A Trivedi
Department of Psychology, Northern Illinois University, DeKalb, IL 60115, USA
Behav Brain Res 168:289-98. 2006..These findings support a role for both the DH and VH in trace fear conditioning, and suggest that the greater effect of VH lesions on conditioned fear might be specific to certain measures of fear...
Reduced hippocampal activation during episodic encoding in middle-aged individuals at genetic risk of Alzheimer's disease: a cross-sectional studyMehul A Trivedi
Geriatric Research Education and Clinical Center, William S Middleton Veteran s Affairs Hospital, Madison, WI, USA
BMC Med 4:1. 2006....
fMRI activation during episodic encoding and metacognitive appraisal across the lifespan: risk factors for Alzheimer's diseaseMehul A Trivedi
Geriatric Research Education and Clinical Center, Wm S Middleton Memorial Veterans Hospital, Madison, WI 53705, USA
Neuropsychologia 46:1667-78. 2008..These results suggest that FH and aging are exerting independent effects in both tasks while APOE affected the relationship with age in the hippocampus in one of the two tasks given...
Anosognosia in mild cognitive impairment: Relationship to activation of cortical midline structures involved in self-appraisalMichele L Ries
Geriatric Research Education and Clinical Center, William S Middleton VA Hospital, Madison, Wisconsin 53705, USA
J Int Neuropsychol Soc 13:450-61. 2007..This finding highlights the level of anosognosia in MCI as an important predictor of response to self-appraisal in cortical midline structures, brain regions vulnerable to changes in early AD...
Longitudinal changes in global brain volume between 79 and 409 days after traumatic brain injury: relationship with duration of comaMehul A Trivedi
William S Middleton Memorial VA Hospital, Geriatric Research Education and Clinical Center GRECC, Madison, Wisconsin 53705, USA
J Neurotrauma 24:766-71. 2007..Greater %BVC was associated with longer duration of post-injury coma. These results confirm previous findings from cross-sectional studies and argue that the brain undergoes continued structural change for several months post-injury...
Task-dependent posterior cingulate activation in mild cognitive impairmentMichele L Ries
William S. Middleton VA Medical Center, GRECC, 2500 Overlook Terrace, 11G, Madison, WI 53705, USA
Neuroimage 29:485-92. 2006..This result suggests in MCI that the PCC shows functional degradation during episodic retrieval; however, the PCC's role in retrieval and evaluation of highly elaborated information regarding the self is more well-preserved...
The effect of body mass index on global brain volume in middle-aged adults: a cross sectional studyMichael A Ward
Geriatric Research Education and Clinical Center, Wm S Middleton VA Hospital, Madison, WI, USA
BMC Neurol 5:23. 2005..The purpose of this study was to determine whether body type affects global brain volume, a marker of atrophy, in middle-aged men and women...
Lesions of the ventral hippocampus, but not the dorsal hippocampus, impair conditioned fear expression and inhibitory avoidance on the elevated T-mazeMehul A Trivedi
Department of Psychology, Northern Illinois University, DeKalb, IL 60115, USA
Neurobiol Learn Mem 81:172-84. 2004..We suggest that the VH may be specifically involved in modulating goal-oriented, defensive behavior expression through hypothalamic and amygdaloid connections...
