Long term impacts of prenatal synthetic glucocorticoids exposure on functional brain correlates of cognitive monitoring in adolescence

Sci Rep
PMCID: 5955898
PMID: 29769646
DOI: 10.1038/s41598-018-26067-3
call_split See protocol

[…] 152 template in Brainstorm. The four different compartments of the head model (scalp, outer and inner skull, cortex) were extracted using the Boundary Element Method (BEM) that is also implemented in OpenMEEG. A Brainstorm provided default brain surface of 15002 nodes was used for computing the aforementioned compartments. sLORETA computes the current source density distribution for every cortical […]


Effect of word association on linguistic event related potentials in moderately to mildly constraining sentences

Sci Rep
PMCID: 5940757
PMID: 29740165

[…] ailable under the GNU general public license. As our head model, we used the ICBM152 template as the default template, an average of 152 subjects. The forward model used to compute the head model was OpenMEEG BEM, for which we took 15000 dipoles uniformly distributed over the cortical surface. For each subject separately, a subset of bad channels (between 2 and 11 channels, avr 5.2) with largest a […]


The neural encoding of information prediction errors during non instrumental information seeking

Sci Rep
PMCID: 5904167
PMID: 29666461

[…] Brainstorm, based on electrode locations relative to a standard Montreal Neurological Institute structural brain (Colin27) and a forward model based upon a boundary element model (BEM) generated with OpenMEEG software. Anterior cingulate cortex activation was then calculated based on coordinates from a standard automatic parcellation of the cingulate cortex into ROIs. Timecourses of source activit […]


A statistical method for analyzing and comparing spatiotemporal cortical activation patterns

Sci Rep
PMCID: 5882928
PMID: 29615797
DOI: 10.1038/s41598-018-23765-w

[…] red and corrected resting state data set of 3 minutes and utilized for all other recordings of the same participant. For MEG, an overlapping spheres head model, for EEG a boundary element model (BEM, OpenMEEG software was utilized. A weighted minimum-norm estimated (wMNE) was then used as inverse solution to project the measured data to the cortical surface with no orientation constraints of the s […]


The FieldTrip SimBio pipeline for EEG forward solutions

Biomed Eng Online
PMCID: 5870695

[…] n to achieve the best combination of accuracy, robustness, and computation speed [, , , ]. Furthermore, the St. Venant FEM was also compared to two BEM approaches, the symmetric BEM as implemented in OpenMEEG [] and a double-layer BEM approach, in both (tetrahedral) sphere models and in a realistic head model. Again, the St. Venant FEM was shown to achieve high accuracies and fast computation spee […]


Observation of Point Light Walker Locomotion Induces Motor Resonance When Explicitly Represented; An EEG Source Analysis Study

[…] ree to assume whichever orientation. The EEG forward modeling of volume currents was completed with a three-layers (head, outer, and inner skull) symmetric boundary element model (BEM) generated with OpenMEEG (Gramfort et al., ). A diagonal noise covariance matrix was computed for each participant using the pre-stim interval to estimate the sensors variance. Sources intensities were estimated thro […]
