open-source electrophysiology

An open-source tetrode twister powered by Arduino.

If your research revolves around tetrode and stereotrode recordings as much as ours does, you've spent a lot of time twisting wires together. Twisted-wire electrodes offer unparalleled single-unit isolation, at the expense of being labor-intensive to produce. Great recordings depend on well-constructed tetrodes, but there's currently no commercial source for the finished product. We created an affordable, easy-to-assemble tetrode twister in order to speed up the tetrode-making process. Build two or more to create your own tetrode twisting assembly line!

Fully assembled Twisters can now be purchased from LabMaker!
