A cultured network of nervous tissue might serve as an interface between a disconnected nervous system of the body and an external stimulation circuit, a so-called 'cultured probe'. To be able to stimulate via this interface the cultured neurons should be positioned on, or in the neighbourhood of, an electrode. Figure 1 gives an example of an electrode configuration and the field of constant force created by it. A cell suspension can be applied to this chamber and when the electrodes are driven with high-frequency signals, the cells are directed to the regions of minimum field strength, due to the dielectrophoretic forces as is shown in Figure 2.
