EEG–fMRI mapping of asymmetrical delta activity in a patient with refractory epilepsy is concordant with the epileptogenic region determined by intracranial EEG [PDF]

, 2006
We studied a patient with refractory focal epilepsy using continuous EEG-correlated fMRI. Seizures were characterized by head turning to the left and clonic jerking of the left arm, suggesting a right frontal epileptogenic region.

Age differences in fMRI adaptation for sound identity and location [PDF]

, 2011
We explored age differences in auditory perception by measuring fMRI adaptation of brain activity to repetitions of sound identity (what) and location (where), using meaningful environmental sounds.

Combined EEG-fMRI and tractography to visualise propagation of epileptic activity [PDF]

, 2008
In a patient with refractory temporal lobe epilepsy, EEG-fMRI showed activation in association with left anterior temporal interictal discharges, in the left temporal, parietal and occipital lobes. Dynamic causal modelling suggested propagation of neural

Kernel methods for fmri pattern prediction

, 2008
In this paper, we present an effective computational approach for learning patterns of brain activity from the fMRI data. The procedure involved correcting motion artifacts, spatial smoothing, removing low frequency drifts and applying multivariate ...

The Neural Correlates of Consciousness and Attention: Two Sister Processes of the Brain

Frontiers in Neuroscience, 2019
During the last three decades our understanding of the brain processes underlying consciousness and attention has significantly improved, mainly because of the advances in functional neuroimaging techniques.

DC Shifts-fMRI: A Supplement to Event-Related fMRI [PDF]

Frontiers in Computational Neuroscience, 2019
Event-related fMRI have been widely used in locating brain regions which respond to specific tasks. However, activities of brain regions which modulate or indirectly participate in the response to a specific task are not event-related. Event-related fMRI can't locate these regulatory regions, detrimental to the integrity of the result that event ...

Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.

A new indwelling urethral catheter (amSafeX) to verify the position of its balloon within the bladder during inflation

Urology Video Journal
Introduction: Inserting a Foley catheter for urethral catheterization can lead to numerous iatrogenic injuries in patients, as it is difficult to ensure that the balloon is in the bladder during inflation.

Preoperative amygdala fMRI in temporal lobe epilepsy [PDF]

, 2009
Purpose: Anterior temporal lobe resections (ATLR) benefit 70% of patients with refractory mesial temporal lobe epilepsy (TLE), but may be complicated by emotional disturbances.
