[HTML][HTML] General overview on the merits of multimodal neuroimaging data fusion

K Uludağ, A Roebroeck - Neuroimage, 2014 - Elsevier
Multimodal neuroimaging has become a mainstay of basic and cognitive neuroscience in
humans and animals, despite challenges to consider when acquiring and combining non-…

A short history of causal modeling of fMRI data

KE Stephan, A Roebroeck - Neuroimage, 2012 - Elsevier
Twenty years ago, the discovery of the blood oxygen level dependent (BOLD) contrast and
invention of functional magnetic resonance imaging (MRI) not only allowed for enhanced …

Ex vivo diffusion MRI of the human brain: Technical challenges and recent advances

A Roebroeck, KL Miller, M Aggarwal - NMR in Biomedicine, 2019 - Wiley Online Library
This review discusses ex vivo diffusion magnetic resonance imaging (dMRI) as an important
research tool for neuroanatomical investigations and the validation of in vivo dMRI …

Mapping directed influence over the brain using Granger causality and fMRI

A Roebroeck, E Formisano, R Goebel - Neuroimage, 2005 - Elsevier
We propose Granger causality mapping (GCM) as an approach to explore directed influences
between neuronal populations (effective connectivity) in fMRI data. The method does not …

Investigating directed cortical interactions in time-resolved fMRI data using vector autoregressive modeling and Granger causality mapping

R Goebel, A Roebroeck, DS Kim… - Magnetic resonance …, 2003 - Elsevier
We present a framework aimed to reveal directed interactions of activated brain areas using
time-resolved fMRI and vector autoregressive (VAR) modeling in the context of Granger …

Mapping the information flow from one brain to another during gestural communication

MB Schippers, A Roebroeck… - Proceedings of the …, 2010 - National Acad Sciences
Both the putative mirror neuron system (pMNS) and the ventral medial prefrontal cortex (vmPFC)
are deemed important for social interaction: the pMNS because it supposedly “…

Hunger is the best spice: an fMRI study of the effects of attention, hunger and calorie content on food reward processing in the amygdala and orbitofrontal cortex

N Siep, A Roefs, A Roebroeck, R Havermans… - Behavioural brain …, 2009 - Elsevier
Research indicates that dysfunctional food reward processing may contribute to pathological
eating behaviour. It is widely recognized that both the amygdala and the orbitofrontal cortex …

[HTML][HTML] Effective connectivity: influence, causality and biophysical modeling

PA Valdes-Sosa, A Roebroeck, J Daunizeau, K Friston - Neuroimage, 2011 - Elsevier
This is the final paper in a Comments and Controversies series dedicated to “The
identification of interacting networks in the brain using fMRI: Model selection, causality and …

The identification of interacting networks in the brain using fMRI: model selection, causality and deconvolution

A Roebroeck, E Formisano, R Goebel - Neuroimage, 2011 - Elsevier
Functional magnetic resonance imaging (fMRI) is increasingly used to study functional
connectivity in large-scale brain networks that support cognitive and perceptual processes. We …

Specialization in the default mode: Task‐induced brain deactivations dissociate between visual working memory and attention

JS Mayer, A Roebroeck, K Maurer… - Human brain …, 2010 - Wiley Online Library
The idea of an organized mode of brain function that is present as default state and suspended
during goal‐directed behaviors has recently gained much interest in the study of human …
