Temperature Coefficient of Nerve Degeneration

Abstract

The temp. coefficient (Q10) for the rate of degeneration of the tibialis nerve of the frog, for the interval between 15-25[degree], is approximately 2.2, corresponding to a figure obtained by previous workers; but the Q10 values show a decided increase at lower temp. levels and a falling off at higher. These results are interpreted as being indicative of the correctness of the hypothesis that the trophic influence of the neurone cell body over the peripheral fiber is chemical in nature.
