Evaluation of a new method for CVD estimation

A new technique for improving the estimation of conduction velocity distributions (CVDs) over a short segment of nerve is investigated experimentally. The technique involves normalizing the nerve-to-electrode transfer functions (NETFs) at a plurality of closely spaced recording sites. CVD´s are estimated from short-segment nerve recordings before and after NETF normalization and the results are compared with a long-distance CVD estimated from the same nerve. Normalization is found to dramatically improve short-distance CVD and to substantially duplicate the long-distance estimate
