Journal ArticleDOI
Regional cerebral blood flow throughout the sleep-wake cycle. An H2(15)O PET study
Allen R. Braun,Thomas J. Balkin,N J Wesenten,Richard E. Carson,M. Varga,Paul Baldwin,S. Selbie,Gregory Belenky,Peter Herscovitch +8 more
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 ArticleDOI
Decoupling of the brain's default mode network during deep sleep
Silvina G. Horovitz,Allen R. Braun,Walter Carr,Dante Picchioni,Thomas J. Balkin,Masaki Fukunaga,Jeff H. Duyn +6 more
TL;DR: By performing functional MRI in humans, it is shown that a natural, sleep-induced reduction of consciousness is reflected in altered correlation between DMN network components, most notably a reduced involvement of frontal cortex.
Journal ArticleDOI
Neural Substrates of Spontaneous Musical Performance: An fMRI Study of Jazz Improvisation
Charles J. Limb,Allen R. Braun +1 more
TL;DR: Investigating improvisation in professional jazz pianists using functional MRI found that improvisation was consistently characterized by a dissociated pattern of activity in the prefrontal cortex: extensive deactivation of dorsolateral prefrontal and lateral orbital regions with focal activation of the medial prefrontal (frontal polar) cortex.
Journal ArticleDOI
Hierarchical and asymmetric temporal sensitivity in human auditory cortices
TL;DR: This work uses single-trial sparse-acquisition fMRI and a stimulus with parametrically varying segmental structure affecting primarily temporal properties to show that both left and right auditory cortices are remarkably sensitive to temporal structure.
