Journal ArticleDOI
Electrophysiological signatures of resting state networks in the human brain.
TL;DR: This work has identified six widely distributed resting state networks and supports for the first time in humans the coalescence of several brain rhythms within large-scale brain networks as suggested by biophysical studies.
Journal ArticleDOI
Complete artifact removal for EEG recorded during continuous fMRI using independent component analysis.
Dante Mantini,Mauro Gianni Perrucci,Simone Cugini,Antonio Ferretti,Gian Luca Romani,C. Del Gratta +5 more
TL;DR: A comprehensive method based on independent component analysis (ICA) for simultaneously removing BCG and ocular artifacts from the EEG recordings, as well as residual MRI contamination left by AAS, which performs significantly better than the AAS method in removing the BCG artifact.
Journal ArticleDOI
Hand motor cortical area reorganization in stroke: a study with fMRI, MEG and TCS maps
P.M. Rossini,Carlo Caltagirone,Alessandro Castriota-Scanderbeg,Paola Cicinelli,C. Del Gratta,M. Demartin,Vittorio Pizzella,R. Traversa,Gian Luca Romani +8 more
TL;DR: Transcranial magnetic stimulation mapping, functional magnetic resonance and magnetoencephalography were used as methods of functional imaging and all yielded consistent results, finding an asymmetrical enlargement and posterior shift of the sensorimotor areas localized in the affected hemisphere.
Journal ArticleDOI
Does cerebrovascular disease affect the coupling between neuronal activity and local haemodynamics
P.M. Rossini,Claudia Altamura,Antonio Ferretti,Fabrizio Vernieri,Filippo Zappasodi,Massimo Caulo,Vittorio Pizzella,C. Del Gratta,G.L. Romani,Franca Tecchio +9 more
TL;DR: This finding suggests that BOLD contrast could be more sensitive than TCD to chronic microvascular impairments, measuring small- rather than large- vessel reactivity.
Journal ArticleDOI
An fMRI investigation on image generation in different sensory modalities: The influence of vividness
M. Olivetti Belardinelli,Massimiliano Palmiero,Massimiliano Palmiero,Massimiliano Palmiero,Carlo Sestieri,Davide Nardo,Davide Nardo,R. Di Matteo,R. Di Matteo,Alessandro Londei,Alessandro D'Ausilio,Antonio Ferretti,C. Del Gratta,G.L. Romani +13 more
TL;DR: The hypothesis that vividness is related to image format: high-vivid subjects would create more analogical representations relying on the same specific neural substrates active during perception with respect to low-violet subjects is supported.
