Journal ArticleDOI
Natural frequencies of human corticothalamic circuits.
Mario Rosanova,Adenauer G. Casali,Valentina Bellina,Federico Resta,Maurizio Mariotti,Marcello Massimini +5 more
TL;DR: TMS findings represent the first direct characterization of the coarse electrophysiological properties of three associative areas of the human cerebral cortex and indicate that, in healthy subjects, each corticothalamic module is normally tuned to oscillate at a characteristic rate.
Journal ArticleDOI
Removal of FMRI environment artifacts from EEG data using optimal basis sets.
Rami K. Niazy,Christian F. Beckmann,Gian Domenico Iannetti,Gian Domenico Iannetti,J M Brady,Stephen M. Smith +5 more
TL;DR: New methods to remove both kinds of artifact from functional magnetic resonance imaging and electroencephalography and a robust algorithm for the accurate detection of heart beat peaks from poor quality electrocardiographic data that are collected for the purpose of BCG artifact removal are described.
Journal ArticleDOI
Rolandic alpha and beta EEG rhythms' strengths are inversely related to fMRI-BOLD signal in primary somatosensory and motor cortex
TL;DR: FMRI correlates of Rolandic alpha and beta rhythms were distinct from those associated with the posterior “classical” alpha rhythm, which correlated inversely with the BOLD signal in the occipital cortex, which seemed to be a general feature of “idle rhythms”.
Journal ArticleDOI
Cortical and subcortical correlates of electroencephalographic alpha rhythm modulation
Bernd Feige,Klaus Scheffler,Fabrizio Esposito,Francesco Di Salle,Jürgen Hennig,Erich Seifritz +5 more
TL;DR: The inverse relationship between EEG alpha amplitude and BOLD signals in primary and secondary visual areas suggests that widespread thalamocortical synchronization is associated with decreased brain metabolism.

Correlating the alpha rhythm to BOLD using simultaneous EEG/fMRI: inter-subject variability.
S.I. Gonçalves,J.C. de Munck,Petra J. W. Pouwels,R. Schoonhoven,Joost P.A. Kuijer,Natasha M. Maurits,Johannes M. Hoogduin,E.J.W. van Someren,Robert M. Heethaar,F.H. Lopes da Silva +9 more
TL;DR: Results suggest that the resting state varies over subjects and, sometimes, even within one subject, as the inter-subject variability of this state should be addressed when comparing fMRI results from different subjects.

The Principles of Psychology
TL;DR: For instance, the authors discusses the multiplicity of the consciousness of self in the form of the stream of thought and the perception of space in the human brain, which is the basis for our work.

Statistical parametric maps in functional imaging: A general linear approach
Karl J. Friston,Andrew P. Holmes,Keith J. Worsley,J-B. Poline,Chris D. Frith,Richard S. J. Frackowiak +5 more
TL;DR: In this paper, the authors present a general approach that accommodates most forms of experimental layout and ensuing analysis (designed experiments with fixed effects for factors, covariates and interaction of factors).
Journal ArticleDOI
Neurophysiological investigation of the basis of the fMRI signal
TL;DR: These findings suggest that the BOLD contrast mechanism reflects the input and intracortical processing of a given area rather than its spiking output, and that LFPs yield a better estimate of BOLD responses than the multi-unit responses.
Journal ArticleDOI
Brain magnetic resonance imaging with contrast dependent on blood oxygenation
TL;DR: In this paper, the authors demonstrate in vivo images of brain microvasculature with image contrast reflecting the blood oxygen level, which can be used to provide in vivo real-time maps of blood oxygenation in the brain under normal physiological conditions.
