Human non-REM sleep and the mean global BOLD signal
(Nature Publishing Group, 2019-11)
A hallmark of non-rapid eye movement (REM) sleep is the decreased brain activity as measured by global reductions in cerebral blood flow, oxygen metabolism, and glucose metabolism. It is unknown whether the blood oxygen ...
Towards opto-magnetic physiology: Concepts and pitfalls of of MRI
(Humana Press Inc., 2018)
The Stability of the Blood Oxygenation Level-Dependent Functional MRI Response to Motor Tasks Is Altered in Patients With Chronic Ischemic Stroke
(LIPPINCOTT WILLIAMS & WILKINS, 2010)
Background and Purpose-Functional MRI is a powerful tool to investigate recovery of brain function in patients with stroke. An inherent assumption in functional MRI data analysis is that the blood oxygenation level-dependent ...
On the role of synchrony for neuron-astrocyte interactions and perceptual conscious processing
(Springer, 2009-10-01)
Recent research on brain correlates of cognitive processes revealed the occurrence of global synchronization during conscious processing of sensory stimuli. In spite of technological progress in brain imaging, an explanation ...

Nonlinear estimation of neural processing time from BOLD signal with application to decision-making
(WILEY-BLACKWELLMALDEN, 2012)
The extraction of information about neural activity timing from BOLD signal is a challenging task as the shape of the BOLD curve does not directly reflect the temporal characteristics of electrical activity of neurons. In ...
From EEG to BOLD: Brain mapping and estimating transfer functions in simultaneous EEG-fMRI acquisitions
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
Simultaneous acquisition of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) aims to disentangle the description of brain processes by exploiting the advantages of each technique. Most studies ...
