Matlab 9.3 r2017b

SPM12 (Statistical Parametric Mapping, The Wellcome Centre for Human Neuroimaging, UCL Queen Square Institute of Neurology, United Kingdom) was used for data preprocessing (Matlab 9.3 R2017b, The Mathworks Inc., United States). Default settings were used if not stated otherwise. Functional images were co-registered with the structural high-resolution scan and normalized (warped) into Montreal Neurological Institute (MNI)-space and resampled to a voxel size of 3 × 3 × 3 mm³ before smoothing using a Gaussian kernel (smoothing width set to 6 mm). The series of ready-pre-processed fMRI NIfTI-files for each individual and visit was then used as input for the statistical analysis as described below. A detailed list of the preprocessing steps can be found in the Supplementary Information.
