Pitfalls in the dipolar model for the neocortical EEG sources

JJ Riera, T Ogawa, T Goto… - Journal of …, 2012 - journals.physiology.org
For about six decades, primary current sources of the electroencephalogram (EEG) have
been assumed dipolar in nature. In this study, we used electrophysiological recordings from …

A state-space model of the hemodynamic approach: nonlinear filtering of BOLD signals

JJ Riera, J Watanabe, I Kazuki, M Naoki, E Aubert… - NeuroImage, 2004 - Elsevier
In this paper, a new procedure is presented which allows the estimation of the states and
parameters of the hemodynamic approach from blood oxygenation level dependent (BOLD) …

[HTML][HTML] An in vivo MRI Template Set for Morphometry, Tissue Segmentation, and fMRI Localization in Rats

…, T Ogawa, Y Iturria-Medina, JJ Riera… - Frontiers in …, 2011 - frontiersin.org
Over the last decade, several papers have focused on the construction of highly detailed
mouse high field magnetic resonance image (MRI) templates via non-linear registration to …

Nonlinear local electrovascular coupling. I: A theoretical model

JJ Riera, X Wan, JC Jimenez… - Human brain …, 2006 - Wiley Online Library
Here we present a detailed biophysical model of how brain electrical and vascular dynamics
are generated within a basic cortical unit. The model was obtained from coupling a …

The micro-architecture of the cerebral cortex: functional neuroimaging models and metabolism

JJ Riera, A Schousboe, HS Waagepetersen… - Neuroimage, 2008 - Elsevier
In order to interpret/integrate data obtained with different functional neuroimaging modalities
(eg fMRI, EEG/MEG, PET/SPECT, fNIRS), forward-generative models of a diversity of brain …

Nonlinear local electrovascular coupling. II: From data to neuronal masses

JJ Riera, JC Jimenez, X Wan… - Human brain …, 2007 - Wiley Online Library
In the companion article a local electrovascular coupling (LEVC) model was proposed to
explain the continuous dynamics of electrical and vascular states within a cortical unit. These …

Brain oscillations: ideal scenery to understand the neurovascular coupling

JJ Riera, A Sumiyoshi - Current opinion in neurology, 2010 - journals.lww.com
Understanding the neurovascular coupling, and hence the associated blood oxygenation
level-dependent signal, will help us to design revolutionary therapies for several brain …

Transplantation of bone marrow stromal cell-derived neural precursor cells ameliorates deficits in a rat model of complete spinal cord transection

…, D Matsuse, Y Kuroda, T Morita, JJ Riera… - Cell …, 2013 - journals.sagepub.com
After severe spinal cord injury, spontaneous functional recovery is limited. Numerous studies
have demonstrated cell transplantation as a reliable therapeutic approach. However, it …

The brain connectivity workshops: moving the frontiers of computational systems neuroscience

KE Stephan, JJ Riera, G Deco, B Horwitz - Neuroimage, 2008 - Elsevier
Understanding the link between neurobiology and cognition requires that neuroscience
moves beyond mere structure–function correlations. An explicit systems perspective is needed …

Cortical origin of theta error signals

…, A Sajad, SP Errington, JD Schall, JJ Riera - Cerebral …, 2023 - academic.oup.com
A multi-scale approach elucidated the origin of the error-related-negativity (ERN), with its
associated theta-rhythm, and the post-error-positivity (Pe) in macaque supplementary eye field (…
