THE RECORDING of compound action potentials has often been used to assess the amount of regeneration of nerves which have been cut and sutured^1-3 or crushed at one point.^3-5 This technique may give a better indication of the state of recovery than histological examination, since, as pointed out by Jacobson and Guth,⁵ the presence of a few axons may not indicate the ability of the nerve to conduct action potentials. In the case of homografts, in situ electrical recordings indicated a definite improvement of regeneration produced by high-voltage electron irradiation of the grafts prior to placement in peripheral nerve defects.⁶ Electrical data have not been available for nerve heterografts, however, as heterografts have been thought unsuccessful until recently.⁷ We wished to record action potentials as an index of recovery in irradiated peripheral nerve heterografts.

A preliminary study was carried out in the rabbit tibial . . . [Full Text PDF of this Article]
