Bioelectronic systems using MultiElectrodes Arrays (MEAs) make possible new experiments, based on long term analysis of neural system at the network level. In this paper we present an experimental platform that processes signals from a 60 electrode MEA and runs event (spike, burst, and stimulus artifact) detection and statistic in real-time. The minimum processing task (storage and monitoring) takes 25 μs and the full one takes 60 μs. The data is available for online and offline analysis: on the computer's screen, on the computer's hard disk, and on the TCP/IP layer.
