In this study titled “A 3D-printed modular implant for extracellular recordings” led by Dr. Jonas Rose at Ruhr University Bochum in Germany, the authors introduce a modular 3D‑printed implant system designed to simplify long‑term extracellular recordings in freely behaving animals. By combining a custom‑fit base plate, detachable microdrives, and protective caps, the approach allows researchers to insert, remove, and reposition electrodes with minimal surgical invasiveness and reduced stress for the subjects.
NeuroNexus’s 32‑channel silicon probes (e.g., the A1x32-Poly3-10mm-50‑177 model) and insertion tools were integral to the recording setup, ensuring reliable and high‑quality neural data. The modular system not only streamlines implant procedures and lowers costs but also helps researchers extend experimental paradigms by easily reusing or replacing key components as needed.
