The mechanisms that link a transient neural activity to the corresponding increase of
cerebral blood flow (CBF) are termed neurovascular coupling (NVC). They are possibly …

Electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) have
proved to be extremely valuable tools for the non-invasive study of human brain function …

Granger causality is a method for identifying directed functional connectivity based on time
series analysis of precedence and predictability. The method has been applied widely in …

This technical note presents a dynamic causal modelling (DCM) procedure for evaluating
different models of neurovascular coupling in the human brain–using combined …

This paper asks whether integrating multimodal EEG and fMRI data offers a better
characterisation of functional brain architectures than either modality alone. This evaluation …

Hemodynamic responses, in general, and the blood oxygenation level-dependent (BOLD)
fMRI signal, in particular, provide an indirect measure of neuronal activity. There is strong …

Transcranial direct current stimulation (tDCS) has been shown to evoke hemodynamics
response; however, the mechanisms have not been investigated systematically using …

Background: The ability to communicate using speech is a remarkable skill, which requires
precise coordination of articulatory movements and decoding of complex acoustic signals …

This technical note introduces adiabatic dynamic causal modelling, a method for inferring
slow changes in biophysical parameters that control fluctuations of fast neuronal states. The …

Many of the major advances in our understanding of how functional brain imaging signals
relate to neuronal activity over the previous two decades have arisen from physiological …
