Electromyogram recordings for internal capsule stimulations in non-human primates

EMG recordings is a common method to confirm implant location. In this protocol, we describe steps to perform EMG recordings during an internal capsule stimulator implant surgery. This procedure maybe performed in both sterile and non-sterile surgeries, but here we only describe the steps for a non-sterile, terminal experiment setup. For step by step guidelines to plan an internal capsule implant surgery with the clinical robot, ROSA ONE Brain, refer to this protocol: dx.doi.org/10.17504/protocols.io.5jyl82rb7l2w/v1 This protocol is supplementary to the manuscript: Liang, L., Zimmermann Rollin, I., Alikaya, A., Ho, J.C., Santini, T., Bostan, A.C., Schwerdt, H.N., Stauffer, W.R., Ibrahim, T.S., Pirondini, E., Schaeffer, D.J., 2024.
