Mutual information between brain and heart activity before an epileptic seizure
Main Article Content
Abstract
The paper analyzes the relation between the brain and cardiovascular system activity in patients with epilepsy in the period before an epileptic seizure. Quantification of the connection by mutual information between full power of electroencephalogram and cardiorhythmogram in time windows for an hour before the seizure is proposed. Clinical study results for ten signals containing seizures showed a significant reduction of the mutual information in 5 minutes before the seizure. Ref. 19, Figs. 3.
