2008 International Conference on BioMedical Engineering and Informatics
The Combination of Amplitude and Sample Entropy in EEG and its Application to Assessment of Cerebral Injuries in Piglets
May 27-May 30

Amplitude and Sample entropy are independent features of electroencephalography. They could reflect cerebral states in different aspects: amplitude denotes the intensity of synchronous neural activities in cortex while SampEn represents the signal complexity of these bioelectrical processes. Yet both of them have limits when applied to estimation of cerebral functions. Present paper introduces a new parameter called Samplitude by combining amplitude and SampEn of EEG. Then amplitude, SampEn and Samplitude are applied to a set of experimental EEGs. The results prove that Samplitude, which has a high separating capacity and a superior noise-proof ability, is a more suitable parameter to estimate cerebral functions.
