Journal ArticleDOI
Acute stress affects heart rate variability during sleep.
Martica H. Hall,Raymond C. Vasko,Daniel J. Buysse,Hernando Ombao,Qingxia Chen,J David Cashmere,David J. Kupfer,Julian F. Thayer +7 more
TL;DR: Autoregressive spectral analysis of the electrocardiogram (EKG) interbeat interval sequence was used to characterize stress-related changes in heart rate variability during sleep in 59 healthy men and women to represent one pathway to disturbed sleep.
Journal ArticleDOI
Human regional cerebral glucose metabolism during non-rapid eye movement sleep in relation to waking
Eric A. Nofzinger,Daniel J. Buysse,Jean M. Miewald,Carolyn C. Meltzer,Julie C. Price,Robert C Sembrat,Hernando Ombao,Charles F. Reynolds,Timothy H. Monk,Martica H. Hall,David J. Kupfer,Robert Y. Moore +11 more
TL;DR: The relative increases in glucose utilization in the basal forebrain, hypothalamus, ventral striatum, amygdala, hippocampus and pontine reticular formation are new observations that are in accordance with the view that NREM sleep is important to brain plasticity in homeostatic regulation and mnemonic processing.
Journal ArticleDOI
SLEX Analysis of Multivariate Nonstationary Time Series
TL;DR: The proposed SLEX analysis gives results that are easy to interpret, because it is an automatic time-dependent generalization of the classical Fourier analysis of stationary time series and hence is able to provide a systematic framework for extracting spectral features from a massive dataset.
Journal ArticleDOI
Prevalence of obesity and weight change during treatment in patients with bipolar I disorder.
Andrea Fagiolini,Ellen Frank,Patricia R. Houck,Alan G. Mallinger,Holly A. Swartz,Daniel J. Buysse,Hernando Ombao,David J. Kupfer +7 more
TL;DR: The high prevalence of obesity in subjects with bipolar disorder emphasizes the need for specific treatment strategies and programs for weight control for these individuals.
Journal ArticleDOI
Automatic statistical analysis of bivariate nonstationary time series
TL;DR: In this article, a smoothed localized complex exponential (SLEX) transform is proposed to segment the time series into approximately stationary blocks and select the span to be used to obtain the smoothed estimates of the time-varying spectra and coherence.
