Abstract
The study and achievement of a discontinuous feedback amplifier to measure membrane potentials and currents in frog atrial fibres using the double sucrose gap technique was achieved. It was shown that, with the present device, the effects of the resistance in series with the membrane resistance and the membrane capacity on the measure of cardiac membrane potentials and fast currents are markedly reduced.
摘要
采用双蔗糖间隙技术，成功研制出一种用于测量青蛙心房纤维膜电位和电流的断续反馈放大器。结果表明，使用当前装置，与膜电阻和膜电容串联的电阻对心脏膜电位和快速电流测量的影响显著降低。
