Founding developers Dennis Kätzel and Sampath Kapanaiah

Dennis Kätzel and Sampath Kapanaiah are at Ulm University where Dennis Kätzel is professor of neurophysiology and specializes in translational psychiatry, with a particular emphasis on schizophrenia and ADHD. This work involves investigating cognitive functions in mice using a variety of tools, including electrophysiological recording and neural circuit modulation. The lab is very keen on making their hardware developments open source tools that become available to the community.

The Open-MAC is a low-torque, Motorized All-in-one Commutator. Operates in torque-based mode with minimal audible noise due to its dual magnetic Hall sensors. Accommodates 128-256 recording channels for electrophysiology and miniature endoscope (miniscope) applications.
