对体外培养的神经胶质细胞和新生动物进行了阻抗测量。据估计，在所研究的材料中存在大约240个细胞。膜的电阻率只能在200周/秒以下的交流频率下测量。对组织施加电击和氯化钾都会导致阻抗迅速下降，然后持续较长时间的上升。描述了各种其他化学试剂的影响，并提供了证据表明这种方法研究神经胶质细胞的有效性。
Impedance measurements were carried out on neuroglia cells from tissue culture and newborn animals as studiedin vitro. Approximately 240 cells were estimated to be present in the material studied. Membrane resistivity could be measured only at a-c frequencies below 200 cycle/sec. Both electric shocks and KCl applied to the tissue produced a rapid drop in impedance followed by a rise of long duration. The effects of various other chemical agents are described, and evidence is presented to show the validity of this method of studying the neuroglia.
