Automatic electrophysiological measuring apparatus / method

摘要

An automatic electrophysiological measuring apparatus to automatically penetrate a glass electrode(s) into the membrane of a Xenopus Oocyte to hold the membrane potential and to automatically measure reactions to the administration of a medicine is to be provided.A glass electrode 103 in the air is moved toward a Xenopus Oocyte 601 held in a cell. Changes in the potential states of the glass electrodes are picked up by a control computer to distinguish the relative positions of the glass electrode 102 and the Xenopus Oocyte 601 and the sequence of electrophysiological measurement so as to penetrate the glass electrode 102 into the Xenopus Oocyte 601, hold the membrane potential and automatically administer the medicine.
