What a great first day at #FENS2024! Come see the open source tools we make in action: our extracellular ephys acquisition board, the UCLA Miniscopes, our new ONIX multimodal system (for neuropixels probes!), the HARP behavior board, and more!

3/3 And, yes, our swag came with a datasheet 🤓. Already looking forward to next year's art project...

1/3 In case you missed the Open Ephys SfN booth this year, here are the designs for our Blinkenbrain chaotic key chain swag: https://github.com/open-ephys/blinkenbrain
It's a smooth-brained, analog, chaotic (in the formal sense) blinky!

This system by
@openephys, Jon Newman, Jack Zhang, Aarón Cuevas-López, Jakob Voigts et al. uses an extremely thin tether that streams a ton of data but keeps behavior intact. Through a lot of engineering it also provides sub-ms closed-loop latencies, 3D-tracking and more. (2/3)

It's an unspoken fact that freely moving lab mice are not really freely moving. We came up with a method to change this. See the preprint: https://biorxiv.org/content/10.1101/2023.08.30.554672v1 (1/3)

3/3 The commutator is extensively documented (https://open-ephys.github.io/commutator-docs/index.html), open-source (https://github.com/open-ephys/onix-commutator), works with https://bonsai-rx.org/, and has an easy path to third-party software integration. We are excited to see what you will do with it!

2/3 They are compatible with a growing number of headstages and miniscopes:
* Miniscope v4 (https://open-ephys.org/miniscope-v4)
* ONIX Headstage-64 (https://open-ephys.github.io/onix-docs/Hardware%20Guide/Headstages/headstage-64/index.html)
* ONIX Neuropixels headstage (https://open-ephys.github.io/onix-docs/Hardware%20Guide/Headstages/headstage-neuropix.html)
* More soon…

Miniscope V4 — Open Ephys

The V4 Miniscope is a head-mounted miniature microscope. It uses wide-field fluorescence imaging to record neural activity in awake, freely moving mice.

1/3 Want to give your mice a gift? Open Ephys Commutators are now available: https://open-ephys.org/commutators/coaxial-commutator! They use the orientation information provided by Miniscopes and ONIX headstages to provide near zero-torque tether commutation during free exploration.

Coaxial Commutator — Open Ephys

The Coaxial Commutator enables tangle-free connection between a stationary data acquisition device and the headstage of a freely-moving animal. It is compatible with any ONIX headstage and Miniscope V4. Active commutation is driven by interfacing with a variety of head-orientation tracking technolog
