“…This step was not necessary in the NO and STN groups. Channels showing a bad signal were interpolated (mean: 2.3 channels) using multiquadric interpolation relying on radial basis functions (Buhmann & Jäger, 2019 ; Jäger, Klein, Buhmann, & Skrandies, 2016 ). Epochs with at least one time‐frame ±80 μV were automatically rejected and the remaining epochs were averaged across trial for each cue separately.…”

“…In the last five years there has been a tremendous amount of publications stating new results on positive definite functions on spheres, see for example [1, 4-6, 9, 13, 17, 19, 20]. Isotropic positive definite functions are used in approximation theory, where they are often referred to as spherical radial basis functions [2,3,12,22] and are for example applied in geostatistics and physiology [8,14]. They are also of importance in statistics where they occur as correlation functions of homogeneous random fields on spheres [15].…”

“…Heat maps were calculated to provide a topographic impression of the myogenic activity distribution over the face for both schemes. A modified 4-nearest neighbor interpolation of the EMG RMS values was used similar to the EEG mapping with the inverse square of the distance as weight (Jäger et al, 2016). Interpolation in EEG mapping is often performed on the basis of spherical functions because the conducting area in EEG is approximately a hemisphere (Lehmann, 1992).…”
