[HTML][HTML] Laterality index in functional MRI: methodological issues
ML Seghier - Magnetic resonance imaging, 2008 - Elsevier
In functional magnetic resonance imaging (fMRI), hemispheric dominance is generally
indicated by a measure called the laterality index (LI). The assessment of a meaningful LI …

fMRI language task panel improves determination of language dominance
WD Gaillard, L Balsamo, B Xu, C McKinney… - Neurology, 2004 - AAN Enterprises
Background: fMRI language tasks reliably identify language areas in presurgical epilepsy
patients, but activation using single paradigms may disagree with the intracarotid …

Variability of fMRI activation during a phonological and semantic language task in healthy subjects
Assessing inter‐individual variability of functional activations is of practical importance in the
use of functional magnetic resonance imaging (fMRI) in a clinical context. In this fMRI study …

[HTML][HTML] Neural correlates of working memory in Temporal Lobe Epilepsy—An fMRI study
It has traditionally been held that the hippocampus is not part of the neural substrate of
working memory (WM), and that WM is preserved in Temporal Lobe Epilepsy (TLE). Recent …
