Description:
The effects of cooling and warming on neural function are reviewed. he literature is presented progressively from the subcellular through the cellular level to the neural systems level. emporal measures relevant to membrane activity, action potentials, synaptic transmission and evoked potentials are all consistently increased with cooling and decreased by warming. he various measures of amplitude at difference levels, and even within similar preparation, however, are contradictory: some laboratories report increased amplitudes with cooling and others decreased amplitudes under similar conditions. mphasis is given to identifying-factors which may resolve the differences. hese include: 1) the rate of temperature change, (2) sites of cooling, stimulation and recording, (3) stimulus characteristics and (4) fundamental differences in temperature sensitivities of different neural tissue. side from aplitudes, traditional methods and refined methods of predicting neural response to temperature are good.
