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!

Come say hi and talk all things open tools and training for ephys, miniscopes and behavior at @CosyneMeeting #Cosyne2024

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

2/3 It has an analog, 2 transistor, chaotic attractor that drives an LED.

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

This system by @OpenEphys, @__jonnew, @jiejackzhang, Aarón Cuevas-López, @jvoigts 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: biorxiv.org/content/10.1101/… (1/3)

We're talking Ohm’s law, voltage dividers, impedance, electrodes, grounding, oscilloscopes, Arduino microcontrollers… and how this is applied in your rig! We’d love to have you: apply now by telling us how learning about ephys acquisition would contribute to your training!

🤔 How do we detect tiny voltage deflections in the brain, amplify, capture and play with them in the computer? Students follow practical exercises to understand a typical acquisition system and build one for EMG from basic electronic components in the #Neurokit 📦we provide.

The feedback we got was that it was fun to have interactive stations but too short! Many thanks to the organizers, especially Yannick and Katja that made this possible remotely. Happy to come back and meet everyone in person :)
