Pathological pattern formation and cortical propagation of epileptic seizures.
The stochastic partial differential equations (SPDEs) stated by Steyn-Ross and co-workers constitute a model of mesoscopic electrical activity of the human cortex. A simplification in which spatial variation and stochastic input are neglected yields ordinary differential equations (ODEs), which are amenable to analysis by techniques of dynamical systems theory. Bifurcation diagrams are develope...
متن کاملInhomogeneous Cortical Synchronization and Partial Epileptic Seizures
OBJECTIVE Interictal synchronization clusters have recently been described in several publications using diverse techniques, including neurophysiological recordings and fMRI, in patients suffering from epilepsy. However, little is known about the role of these hyper-synchronous areas during seizures. In this work, we report an analysis of synchronization clusters jointly with several network me...
متن کاملPattern formation and cortical maps.
The response selectivities of neurons in adult primary sensory cortices depend on intricate patterns of synaptic connections; these selectivities are arranged over cortex in equally rich fashion. Characterising these patterns, and particularly the activity-dependence (and independence) of their developmental trajectories, has been a major task for experimental and theoretical neuroscience. Here...
متن کاملEpileptic seizures and syndromes.
This article describes the main characteristics of the different types of seizures and their classifications. The main types of epilepsies are reviewed, including their main, clinical, and EEG features and an overview of their treatment.
متن کاملPrediction of epileptic seizures.
For almost 40 years, neuroscientists thought that epileptic seizures began abruptly, just a few seconds before clinical attacks. There is now mounting evidence that seizures develop minutes to hours before clinical onset. This change in thinking is based on quantitative studies of long digital intracranial electroencephalographic (EEG) recordings from patients being evaluated for epilepsy surge...
