Retest reliability of location-based parameters. A Average Dice Coefficients (DC) describing the overlap of the activation cluster in the first session with the activation cluster of the second session, with higher values indicating more and lower values indicating less overlap. Values on the diagonal represent same-digit overlap: activation clusters for the same digit are compared between sessions. Values off the diagonal represent comparisons between the area of overlap of neighboring digits between sessions: the area that is common for the activation cluster of two digits in the first session is compared to the common area of the same two digits in the second session. The orange-colored side represents values for the TW design and the cyan colored side represents values for the BD. B All three axes (X, Y, and Z; rows) of each digit’s center of gravity (CoG) were correlated across the first and second session for both designs (columns). Data points represent individual data. All digits in all dimensions achieved significant correlation values indicating high stability of the location of the CoG. C. D1-D5 distances were correlated between the first and second session for both designs (colors). Data points represent individual data. Both designs achieved significant correlation values, indicating that the D1-D5 distance is a stable measure of the size of the somatosensory area of digit representation.
