Angelo got the first ‘modern’ ephys recording from the brain of an axolotl! He said: “Many thanks to Open Ephys for making the acquisition setup so simple and yet powerful, so I could focus on the experiment.” Glad we could help, and thanks for sharing your summer science with us!

Jack recorded from the butterfly ventral nerve cord during visual stimulation. Using multiple headstages simultaneously was especially useful.

Butterflies and axolotls: our acquisition systems had a busy summer at the MBL @mblscience.bsky.social ! 🦋🧠 This year, we supported Grass Fellow Jack Supple and Whitman Fellow Angelo Forli @aforli89.bsky.social with Open Ephys acquisition boards. Here’s what they’ve been up to.

A summer of science at MBL: Jack Supple, Grass Fellow from Imperial College London, in the lab beside an Open Ephys recording setup, and Angelo Forli, Whitman Fellow from Istituto Italiano di Tecnologia, at the MBL waterfront.

The low-profile SPI Headstage 64ch is ideal for promoting naturalistic behavior, as it significantly reduces torque on the animal's head in comparison with the SPI Headstage 32ch version 🌱🐁

Open Ephys @open-ephys.org · 17/07/2025

Each headstage includes an embedded 9-axis IMU that senses absolute orientation, from which you can get pitch, yaw, and roll movements and drive our torque-free SPI commutator 🌀 We have three variants of our 3D capable SPI headstages: 32ch unipolar, 64ch unipolar low-profile and 16ch bipolar 📈
