In vivo electrophysiology experiments are widely used in neuroscience to investigate brain activity, yet setups can be expensive with multiple subjects. Eyal Kimchi and colleagues developed OpBox, an open-source in-vivo electrophysiology hardware and software package. The OpBox setup aims to lower the cost of electrophysiology recordings in behaving animals; costing only $500 per subject compared to commercial recording devices which cost thousands of dollars per subject. OpBox scripts, coded in MATLAB, collect and display EEG and EMG data in real-time from multiple subjects. Recording from subjects simultaneously increases experimental efficiency and enables reproducibility across laboratories. The OpBox hardware includes a multichannel amplifier which produces analog outputs and streams information to data acquisition devices. This open-source design also allows for modular combinations of video cameras and behavior devices depending on the experimental design. The code and the required hardware can be found on the Kimchi Lab GitHub site: https://github.com/KimchiLab/OpBoxPhys.
