Time-frequency-space components of somatosenory evoked potentials in rats

Abstract

This paper presents a description of components extracted from somatosensory evoked potentials recorded from rats after electrical stimulation of the forelimb. For the decomposition of SEPs Topographic Matching Pursuit method was used. This method is able to decompose multichannel data into spatio-temporal atoms defined by only a few parameters. Such parameterization allows convenient processing and analysis of data components. In the present study four distinct components could be identified in the SEP data. © 2011 Springer-Verlag Berlin Heidelberg.
