Abstract

PURPOSE: Functional imaging studies have identified a common network of brain regions that activate and deactivate during the generalised spike wave (GSW) discharges of childhood absence epilepsy (CAE). Functional connectivity within this network is also altered during the resting state. In this study our aim was to assess functional connectivity throughout the whole brain of patients with CAE. METHODS: We studied a group of eleven patients with untreated CAE and eleven matched controls using resting-state fMRI. We measured functional connectivity between every pair of voxels and generated images of "whole-brain" functional connectivity by counting the number of functional connections of eac..
