Journal ArticleDOI
Decomposing EEG data into space-time-frequency components using Parallel Factor Analysis.
Fumikazu Miwakeichi,Eduardo Martínez-Montes,Pedro A. Valdes-Sosa,Nobuaki Nishiyama,Hiroaki Mizuhara,Yoko Yamaguchi +5 more
TL;DR: It is shown that the proposed decomposition can be used to search for activity with a given spectral and topographic profile in new recordings, and that the method may be useful for artifact recognition and removal.
Journal ArticleDOI
Effective connectivity: Influence, causality and biophysical modeling
TL;DR: It is argued that discovering effective connectivity depends critically on state-space models with biophysically informed observation and state equations, and some of the challenges faced in this field have promising solutions and speculate on future developments.
Journal ArticleDOI
Concurrent EEG/fMRI analysis by multiway Partial Least Squares
Eduardo Martínez-Montes,Pedro A. Valdes-Sosa,Fumikazu Miwakeichi,Robin I. Goldman,Mark S. Cohen +4 more
TL;DR: The results of N-PLS analysis indicate that some electrical sources may be intrinsically invisible to scalp EEG, yet may be revealed through conjoint analysis of EEG and fMRI data, and expose brain regions that participate in the control of brain rhythms but may not themselves be generators.
Journal ArticleDOI
Estimating brain functional connectivity with sparse multivariate autoregression
Pedro A. Valdes-Sosa,Jose M. Sanchez-Bornot,Agustin Lage-Castellanos,Mayrim Vega-Hernández,Jorge Bosch-Bayard,Lester Melie-Garcia,Erick J. Canales-Rodríguez +6 more
TL;DR: Methods are introduced for dealing with the identification of neural circuitry related to emotional processing as measured by BOLD by using sparse MAR models and it is shown that the detection efficiency of connections of the proposed procedure is quite high.
Journal ArticleDOI
Intracerebral sources of human auditory-evoked potentials.
Terence W. Picton,Claude Alain,David L. Woods,Michael Sasha John,Michael Scherg,Pedro A. Valdes-Sosa,Jorge Bosch-Bayard,N. J. Trujillo +7 more
TL;DR: Brain electric source analysis and variable-resolution electromagnetic tomography analyses showed that the dominant intracerebral sources for the late auditory-evoked potentials were in the supratemporal plane and lateral temporal lobe contralateral to the ear of stimulation.
