README
README.mdHead-fixed Behavior
This repository contains information about an open-source, multisensory head fixed setup for operant conditioning. Here, we want to share all relevant information about the setup used in the publication "Single-trial neural dynamics are dominated by richly varied movements" by Musall et al. One example of using the setup is the PuffyPengiun paradigm for multisensory stimulation.
Overview
Operant conditioning is essential for quantifying animal perception. We developed a head-fixed setup to measure the behavioral output of animals while recording their brain activity with optophysiological and electrophysiological methods. This setup can perform a variety of protocols ranging from auditory, visual, tactile and even multi sensory. The protocols themselves are highly customizable so that they can be tailored precisely to the respective research objective.
Installation
Please refer to the manual for detailed installation steps.
Software
At the moment the setup is running with Matlab, Bpod (Matlab based). To prepare your experiments start Matlab and enter "bpod" into the console. This will open the Bpod GUI. Flush the spouts and press the start button after the spouts are flushed (this has to be calibrated occasionally). Afterwards, choose your paradigm and adjust your subject and settings. Adjust your spouts positions to a proper one and press the "give water" button. Place your mouse into the setup and head fix it. The lick detection threshold may need to be adjusted. Toggle the button in the upper left from pause to run. If your experiment is done press the "stop" button.
Future
Stay tuned for new paradigms and new features of the head-fixed setup.
Currently we are working on automation of data management and mouse detection.

Questions
How big is the Breakout v4 PCB?
It measures 222 × 70 mm and has 2 copper layers, 0.41 mm thick.
What parts does the Breakout v4 use?
47 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Breakout v4 KiCad files?
From the musallGroup/HeadFixedSetup repository on GitHub, at the commit this page was made from: the board is parts/Breakout/Breakout_v4 (23.02.2026 07-45)/KiCAD/Breakout_v4.kicad_pcb and its schematic parts/Breakout/Breakout_v4 (23.02.2026 07-45)/KiCAD/Breakout_v4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Breakout v4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask musallGroup before reusing the design.
