Studies in nerve electrophysiology

Two separate studies in nerve electrophysiology are described. Both are seen to have clinical relevance in terms of the treatment and diagnosis of peripheral nervous system dysfunction and injury. The first study, "Electrophysiological and Histological Studies of Laser and Suture Anastomoses in Rat Sciatic Nerves," compares a conventional epineurial suture repair technique to a "laser-assist" technique which combines fewer epineurial sutures with CO$\sb2$ laser welds to seal the epineurium. The second study, "Potential Field from an Active Nerve in an Inhomogeneous Anisotropic Volume Conductor-Experimental Verification of the Inverse Problem", a field theoretic technique previously presented in the literature for the recovery of CAPs originating from nerves embedded in a muscular limb containing a bone via field potentials recorded on the surface of the limb is discussed. This technique was tested experimentally in a bullfrog thigh containing a single sciatic nerve source. (Abstract shortened with permission of author.
