Dynamic modeling of neuronal responses in fMRI using cubature Kalman filtering
TLDR
This paper presents a new approach to inverting (fitting) models of coupled dynamical systems based on state-of-the-art Kalman filtering, which promises to provide a significant advance in characterizing the functional architectures of distributed neuronal systems, even in the absence of known exogenous input.

Error processing – evidence from intracerebral ERP recordings
TLDR
The findings firstly show that multiple cortical structures generate Ne and Pe; in addition to the rostral anterior cingulate cortex, the mesiotemporal and some prefrontal cortical sites seem to represent integral components of the brain’s errorchecking system. Expand
fMRI evaluation of hemispheric language dominance using various methods of laterality index calculation
TLDR
The most significant correlation with Wada was proven in the LIs that were evaluated from Broca's area, and the new LI calculation methods used in the present study did not produce a statistically significant benefit in comparison to previously reported methods. Expand
Atypical hemispheric language dominance in left temporal lobe epilepsy as a result of the reorganization of language functions
TLDR
The results strongly support the influential impact of epileptiform activity spreading from the left temporal lobe structures on the reorganization of language functions in patients with early brain injury. Expand
Effects of spatial smoothing on fMRI group inferences.
TLDR
This study presents a broad perspective on the influence of spatial smoothing on fMRI group activation results and concludes that for robust experiments and an adequate number of subjects in the study, the optimal FWHM for single-subject inference is similar to that for group inference (about 8 mm, according to spatial resolution).

Vagus nerve stimulation: Longitudinal follow-up of patients treated for 5 years
TLDR
VNS is an effective and safe method to refractory epilepsy in common clinical practice and in concordance with the decrease of overall seizure frequency in patients who have received this treatment for at least 5 years. Expand
Dynamic Granger causality based on Kalman filter for evaluation of functional network connectivity in fMRI data
TLDR
This work proposes an approach to dynamic Granger causality in the frequency domain for evaluating functional network connectivity in fMRI data and demonstrates the effectiveness and robustness of the dynamic approach, significantly improved by combining a forward and backward Kalman filter that improved estimates compared to the standard time-invariant MAR modeling. Expand
Occurrence and lateralizing value of “rare” peri-ictal vegetative symptoms in temporal lobe epilepsy
TLDR
Both pC and pWD have a significant lateralizing value in TLE, and both pWD and pC occurred significantly more often in those with TLE of the non- language-dominant hemisphere. Expand
Directional functional coupling of cerebral rhythms between anterior cingulate and dorsolateral prefrontal areas during rare stimuli: A directed transfer function analysis of human depth EEG signal
TLDR
Support is provided to the hypothesis that ACC directly or indirectly affects the oscillatory activity of dorsolateral PFC by a selective frequency code under typical oddball conditions. Expand
Intracerebral event-related potentials to subthreshold target stimuli
TLDR
A crucial role of the large-scale neural system for conscious experience of perception is suggested, which is distributed extensively among the dorsal posterior association areas and the prefrontal cortex, with the dominant part being that of the right hemisphere. Expand
