Abstract :
The goal of this paper is to develop a multifunctional measurement system for neuron-microelectrode interface study by LabVIEW. The system uses a commercial 60-channel microelectrode array (MEA) as an interface platform. These online functions of neuronal stimulation, extracellular potential recording, impedance monitoring, and data storage have been integrated into this system. Two offline analysis functions of wavelet de-noising and artifact removing are also included. The former two online functions are executed respectively by a NI-DAQ card and by a self-made analog frond-end amplifier, and Agilent 4284A LCR meter makes the impedance measurement. We have completed the basic functional verifications on a cultured MEA with PC-12.
