Assessing hippocampal functional reserve in temporal lobe epilepsy: A multi-voxel pattern analysis of fMRI data
Assessing the functional reserve of key memory structures in the medial temporal lobes (MTL) of pre-surgical patients with intractable temporal lobe epilepsy (TLE) remains a challenge. Conventional functional MRI (fMRI) memory paradigms have yet to fully convince of their ability to confidently assess the risk of a post-surgical amnesia. An alternative fMRI analysis method, multi-voxel pattern ...
متن کاملMulti-Voxel Pattern Analysis of fMRI Data
The central goal of cognitive neuroscience is to understand how information is processed in the brain. To accomplish this goal, researchers studying human cognition are increasingly relying on multi-voxel pattern analysis (MVPA); this method involves analyzing spatially distributed (multi-voxel) patterns of functional MRI activity, with the goal of decoding the information that is represented a...
متن کاملComparison of temporal lobe epilepsy with hippocampal sclerosis and temporal lobe epilepsies due to other etiologies
Background: This study compares the clinical characteristics of patients with mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS) with those who have temporal lobe epilepsy (TLE) due to other etiologies. Methods : In this retrospective study all patients with a clinical diagnosis of TLE were recruited in a referral outpatient epilepsy clinic at Shiraz University of Medical Sc...
متن کاملBeyond mind-reading: multi-voxel pattern analysis of fMRI data.
A key challenge for cognitive neuroscience is determining how mental representations map onto patterns of neural activity. Recently, researchers have started to address this question by applying sophisticated pattern-classification algorithms to distributed (multi-voxel) patterns of functional MRI data, with the goal of decoding the information that is represented in the subject's brain at a pa...
متن کاملFunctional connectivity of hippocampal networks in temporal lobe epilepsy.
OBJECTIVE Temporal lobe epilepsy (TLE) affects brain areas beyond the temporal lobes due to connections of the hippocampi and other temporal lobe structures. Using functional connectivity magnetic resonance imaging (MRI), we determined the changes of hippocampal networks in TLE to assess for a more complete distribution of abnormality. METHODS Regions of interest (ROIs) were defined in the ri...
