Silicon microprobes

We have developed silicon microprobes containing up to 256 electrodes optimized for recording large-scale neural activity (single-unit and LFP). Thanks to support from the NSF NeuroNex program we have previously offered large quantities of microprobes as open-source, low-cost tools to the neuroscience community. In total we have shared nearly 2,000 probes with dozens of labs around the world. We are no longer actively engaged in disseminating these tools, but continue to heavily rely on silicon probes in our own neuroscience research. The technology can be combined with optical fibers to enable electrophysiology alongside optogenetics or photometry. Further information on their design and use is provided below:
