Transverse Electric Impedance of Nitella
Alternating current measurements have been taken on single Nitella cells over a frequency range from 30 to 2,500,000 cycles per second with the current flow perpendicular to the axis of the cell. The measuring cells were so constructed that electrolytes of any desired concentration could be circulated during the course of the measurements. The cellulose wall which surrounds the cell is found to...
متن کاملElectric Impedance of Nitella during Activity
The changes in the alternating current impedance which occur during activity of cells of the fresh water plant Nitella have been measured with the current flow normal to the cell axis, at eight frequencies from 0.05 to 20 kilocycles per second, and with simultaneous records of the action potential under the impedance electrodes. At each frequency the resting cell was balanced in a Wheatstone br...
متن کاملTransverse Viscoelastic Extension in Nitella
Transverse vicoelstic extensbli was measued directdy in isolated wails of Nitella internode cell. Cell wails extended transversely exhibit a yield point which is approximately twice the yield point in the lontudinal direction. Walk from youn, growing cels are four to seven times more extenble t than transversely, whrle wall from mature, norowng cells are only two times more extensibe longtdinlb...
متن کاملTransverse Electric Impedance of the Squid Giant Axon
The impedance of the excised giant axon from hindmost stellar nerve of Loligo pealii has been measured over the frequency range from 1 to 2500 kilocycles per second. The measurements have been made with the current flow perpendicular to the axis of the axon to permit a relatively simple analysis of the data. It has been found that the axon membrane has a polarization impedance with an average p...
متن کاملElectric Impedance
Electrical impedance tomogram of the mammary gland (EIM). Seven planes of scanning. In the sixth and the seventh scans, a retromammary tissue is visualized. It can be used to distinguish tissues and identify pathologies. Lorentz force electrical impedance tomography is an ultrasoundbased medical imaging technique. In this study, a new platform based on electric cell-substrate impedance sensing ...
