We used the Lead-DBS toolbox (Horn and Kühn, 2015) to reconstruct the electrode trajectories and contact locations for all recorded patients (Figure 2A). Postoperative CT was co-registered to preoperative T1 MRI using a two-stage linear registration as implemented in Advanced Normalization Tools (ANT) (Avants et al., 2008). CT and MRI were spatially normalized into MNI_ICBM_2009b_NLIN_ASYM space (Fonov et al., 2011). Electrodes were automatically pre-localized in native and template space using the PaCER algorithm (Husch et al., 2018), manually localized based on postoperative CT, and then warped into template (Horn and Kühn, 2015; Horn et al., 2019).
