  • Title: Extraction of short-latency evoked potentials using a combination of wavelets and evolutionary algorithms.
    Author: Turner S, Picton P, Campbell J.
    Journal: Med Eng Phys; 2003 Jun; 25(5):407-12. PubMed ID: 12711238.
    Abstract:
    Somatosensory evoked potentials, recorded at the spine or scalp of a patient, are contaminated by noise. It is common practice to use ensemble averaging to remove the noise, which usually requires a large number of responses to produce one averaged signal. In this paper a post-processing technique is shown which uses a combination of wavelets and evolutionary algorithms to produce a representative waveform with fewer responses. The most suitable wavelets and a set of weights are selected by an evolutionary algorithm to form a filter bank, which enhances the extraction of evoked potentials from noisy recordings.
