  1. The number of subjects categorized (a) according to the types of reported sensation descriptors and (b) the locations of sensations across three sonication conditions (SIFUS, SIIFUS, and SI/SIIFUS) out of 9 responsive subjects (‘h1’–‘h9’). Detailed information of the elicited sensations from each subject can be found in Additional file 1: Tables S1–S3
