[New approach to determining sensitive innervation zones]

Despite a vast body of studies carried out over the past years, there is no single definite opinion about the topography of sensitive innervation zones. The reason, underlying such a situation, is analyzed in the report. Based on laser dopplerfluorometry and evoked somato-sensory potentials, an original method for determining autonomic innervation zones is described. High sensitivity of the method allows measuring dermatome topography in the absence of corresponding clinical disorders.
