Journal ArticleDOI
Reduced prefrontal activity predicts exaggerated striatal dopaminergic function in schizophrenia.
Andreas Meyer-Lindenberg,Robert S. Miletich,Philip Kohn,G. Esposito,Richard E. Carson,Mario Quarantelli,Daniel R. Weinberger,Karen F. Berman +7 more
TL;DR: The tight within-patient coupling of these values, with decreased PFC activation predicting exaggerated striatal 6-fluorodopa uptake, supports the hypothesis that prefrontal cortex dysfunction may lead to dopaminergic transmission abnormalities.
Journal ArticleDOI
Modulation of cognition-specific cortical activity by gonadal steroids: A positron-emission tomography study in women
Karen F. Berman,Peter Schmidt,David R. Rubinow,Merry A. Danaceau,John D. Van Horn,G. Esposito,Jill L. Ostrem,Daniel R. Weinberger +7 more
TL;DR: Data from H215O positron-emission tomography demonstrate that the hormonal milieu modulates cognition-related neural activity in humans during three pharmacologically controlled hormonal conditions spanning 4-5 months.
Journal ArticleDOI
H215O PET validation of steady‐state arterial spin tagging cerebral blood flow measurements in humans
Frank Q. Ye,Karen F. Berman,Timothy M. Ellmore,G. Esposito,John D. Van Horn,Yihong Yang,Jeff H. Duyn,A. M. Smith,Joseph A. Frank,Daniel R. Weinberger,Alan C. McLaughlin +10 more
TL;DR: The work presented here compared CBF values measured using steady‐state arterial spin tagging with CBFvalues measured in the same group of human subjects using the H215O IV bolus PET method.
Journal ArticleDOI
A comparison of rCBF patterns during letter and semantic fluency.
Monica L. Gourovitch,B.S. Kirkby,Terry E. Goldberg,Daniel R. Weinberger,James M. Gold,G. Esposito,John D. Van Horn,Karen F. Berman +7 more
TL;DR: In this paper, the functional neuroanatomies underlying letter and category fluency were evaluated with oxygen-15 water regional cerebral blood flow positron emission tomography (PET) in 18 normal controls.
Journal ArticleDOI
Context-dependent, neural system-specific neurophysiological concomitants of ageing: mapping PET correlates during cognitive activation.
TL;DR: Results indicate that, despite some cognitive overlap between the two tasks and the age-related cognitive decline in both, many of the changes in rCBF activation with age were task-specific, reflecting functional alteration of the different neural circuits normally engaged by young subjects during the WCST and RPM.
