Abstract
A device is disclosed for electrophysiological studies on biological material. The device comprises a support on which an array of measurement electrodes is arranged. A vessel is provided having a cavity for the biological material and an appropriate culture medium. The vessel is arranged on the support around the measurement electrodes in such a way that the latter are in electrical contact with the cavity. By means of a counter electrode, which is permanently arranged in the cavity, electrical signals can be measured between the measurement electrodes and the counter electrode.
