Abstract:

The electrical interfacing of individual nerve cells and silicon microstructures is considered,as well as the assembly of elemen- tary hybrid systems made of neuronal networks and semiconductor microelectronics.Without electrochemical processes,coupling of the electron-conducting semiconductor and the ion-conducting neurons relies on a close contact of cell membrane and oxidised silicon with a high resistance of the junction and a high conductance of the attached membrane.Neuronal excitation can be elicited and recorded from the chip by capacitive contacts and by field-effect transistors with an open gate.Integrated iono- electronic system are obtained by the outgrowth of neuronal networks on the surface of the silicon chip,by implementing electrical circuits in the chip and by two-way interfacing of the neuronal and the electronic components.
