The response rates were derived as ‘the number of sonication events that elicited tactile sensations with respect to the number of sonication events (i.e., 20 events).’ For the FUS conditions of SII_FUS and SI/SII_FUS, the rates were tabulated for each sensation-specific session (V vibrotactile, P pressure, W warmth, C coolness), along with the average response rate across the sessions shown as a separate column (Ave). Mean and SD were derived without including the non-responsive cases (denoted as ‘NR’)
