Abstract
<p>By forming multiple microholes and 64 microelectrodes at the center of a transparent SiN (silicon nitride) diaphragm, we developed a microdevice for chemical stimulation and multichannel measurement of extracellular potentials of cells and tissues. A rat hippocampal slice which was placed on the device was electrically stimulated using one of the 64 microelectrodes, and evoked potentials were measured at multiple areas of the slice. We chemically stimulated the slice by tetrodotoxin molecules released from the microholes, and succeeded in detecting disappearance of the potentials which was caused by inhibition of neural firing.</p>
