Journal ArticleDOI

Regional cerebral blood flow throughout the sleep-wake cycle. An H2(15)O PET study

Allen R. Braun, +8 more
- 01 Jul 1997 - 
TL;DR: Stages of sleep may be characterized by activation of widespread areas of the brain, including the centrencephalic, paralimbic and unimodal sensory regions, with the specific exclusion of areas which normally participate in the highest order analysis and integration of neural information.
Journal Article

Brain blood flow measured with intravenous H2(15)O. II. Implementation and validation.

Marcus E. Raichle, +4 more
- 01 Sep 1983 - 
TL;DR: The well-known tissue autoradiographic technique for the measurement of regional cerebral blood flow (CBF) is adapted using positron emission tomography (PET) and intravenously administered oxygen-15-labeled water and the correlation between CBF measured with PET and the true CBF for the same cerebral hemisphere was excellent.
Journal ArticleDOI

Dissociation of object and spatial visual processing pathways in human extrastriate cortex

James V. Haxby, +8 more
- 01 Mar 1991 - 
TL;DR: The ventral and dorsal locations of the regions specialized for object recognition and spatial localization, respectively, suggest some homology between human and nonhuman primate extrastriate cortex, with displacement in human brain, possibly related to the evolution of phylogenetically newer cortical areas.
Journal Article

Brain Blood Flow Measured with Intravenous H215O. I. Theory and Error Analysis

Peter Herscovitch, +2 more
- 01 Sep 1983 - 
TL;DR: Simulation showed that the tissue autoradiographic method for the measurement of regional cerebral blood flow in animals was adapted for use with positron emission tomography and was accurate in the presence of ischemia or hyperemia of the gray matter.
Journal ArticleDOI

Brain activity during transient sadness and happiness in healthy women.

Mark S. George, +5 more
- 01 Mar 1995 - 
TL;DR: Transient sadness and happiness in healthy volunteer women are accompanied by significant changes in regional brain activity in the limbic system, as well as other brain regions, which have implications for understanding the neural substrates of both normal and pathological emotion.
