EFFECT OF THE CONNECTIVE TISSUE SHEATH ON THE VALUE OF THE ACCOMMODATION CONSTANT λ OF A NERVE FIBER

Abstract

It has been found that the value of the accommodation constant λ, measured with the isolated single nerve fiber part, was generally larger than that with the whole nerve part of the same preparation and that the λ value was independent from the interpolar length of the whole nerve part. For explaining these results, the λ value of the fiber with the parallel shunting resistance of several kΩ, and that without it were comparatively measured and they were found to be almost the same. These results indicate the high polarizability of the connective tissues, which distorts the applied current, resulting in a smaller value of λ. Thus it may be concluded that the connective tissue is polarizable for the transverse current, while it is only an ohmic resistance for the longitudinal current.
