Analysis of electrophysiological activities using Matrix Pencil Method

This paper presents a high resolution method for analyzing of electrophysiological activities using Matrix Pencil Method (MPM). This approach identifies measured signal from nerves to better understanding the functional organization of neuronal ensembles that form the peripheral nerves or the cerebral cortex. Matrix Pencil Method which is used to extract original signals and benefits from minimum exponential functions while having excellent reproducibility feature. MPM also can eliminate the noise part of the system and return pure original signal. In this paper, MPM is used to reconstruct recorded action potential from cockroach by using Matlab environment which shows less than 4% error.
