Introducing a new, industrially manufactured semiconductor chip with 2000 sensors based on open field-effect transistors, the applicability of the Neuron-Silicon-Junction for spatiotemporal measurements of neural activity is examined. The chip was designed in cooperation with chip manufacturer Siemens and further developed while working on this project. The crucial points for the concept of a multi-site chip are worked out, and several succeeding generations of chips are characterized accordingly. The basic functionalities of the chip are demonstrated by coupling experiments on leech and snail cells. The first multi-site experiment was performed using 49 sensors recording the field potentials of an organotypic slice culture of the rat.
