MEABench: A Toolset for Multi-electrode Data Acquisition and On-line Analysis
Proc. 2nd Int. IEEE EMBS Conf. Neural Eng. (2005), 518–521. [Preprint (pdf)]
We present a software suite, MEABench, for data acquisition and online analysis of multi-electrode recordings, especially from micro-electrode arrays. Besides controlling data acquisition hardware, MEABench includes algorithms for real-time stimulation, artifact supression and spike detection, as well as programs for online display of voltage traces from 60 electrodes and continuously updated spike raster plots. MEABench features real-time output streaming, allowing easy integration with stimulator systems. We have been able to generate stimulation sequences in response to live neuronal activity with less than 20 ms lag time. MEABench is open-source software, and is available for free public download at http://www.its.caltech.edu/~pinelab/meabench.html.
