Permutation entropy of scalp EEG: A tool to investigate epilepsies

Highlights • We evaluated permutation entropy (PE) extracted from different electrodes in patients with typical absences (TAs) and healthy subjects. • In patients with TAs there was a recurrent behavior of PE topography, with electrodes from anterior regions associated to higher randomness and elect...

Description
Summary:Highlights • We evaluated permutation entropy (PE) extracted from different electrodes in patients with typical absences (TAs) and healthy subjects. • In patients with TAs there was a recurrent behavior of PE topography, with electrodes from anterior regions associated to higher randomness and electrodes from posterior regions associated to lower randomness. • PE seems a useful tool to disclose abnormalities of cerebral electric activity not revealed by conventional EEG.
