A method is described for the detection of EEG transient events that are characterized by transient decrease in the correlation between homologous frequency-band components of different traces. It consists of the following steps: computation of frequency-band components; computation of normalized correlation; application of two thresholds (one for the recognition of an event, and the other for the measure of the event time-length). The method also provides a classification of the detected events. The results can be subjected to statistical analyses. An application is described to seizure-free EEGs of epileptic subjects.

Abstract
A method is described for the detection of EEG transient events that are characterized by transient decrease in the correlation between homologous frequency-band components of different traces. It consists of the following steps: computation of frequency-band components; computation of normalized correlation; application of two thresholds (one for the recognition of an event, and the other for the measure of the event time-length). The method also provides a classification of the detected events. The results can be subjected to statistical analyses. An application is described to seizure-free EEGs of epileptic subjects.| File | Dimensione | Formato | |
