MEA Data Sharing
We have been sharing multi-electrode array data for years, long before the NIH and NSF began to ask for “data sharing” policies in grant proposals. One of our best-cited papers describes how cortical cultures develop interesting patterns of activity in vitro. This was the work of Daniel Wagenaar, when he was a PhD student at Caltech. We have made the entire dataset (over 40 GB) freely available for you to analyze further. A number of independent labs have done this and published their own findings about the data.

We also have many gigs worth of MEA data recorded from cultures undergoing optogenetic control using our OptoClamp closed-loop system. This is the work of former PhD students, Jonathan Newman and Ming-fai Fong, as described in these papers:

Code and Electronics Sharing
The details of how to make your own NeuroRighter multi-unit electrophysiology system can be found here. NeuroRighter was created and used in vivo by former MD/PhD student John Rolston, and re-created, added to, and tested in vivo and in vitro by former PhD student Jonathan Newman (and our collaborators in Garrett Stanley’s lab). Jon Newman also created the high-speed LED controller for optogenetic experiments, Cyclops, that made the OptoClamp possible. He has made detailed plans for it available as part of the OpenEphys project, here.

The precursor to NeuroRighter was Daniel Wagenaar’s MEABench, a set of software and hardware tools that made closed-loop all-electrode stimulation and MEA electrophysiology possible for the first time. Here is the MEABench web page. MEABench-related papers include:
