Figure Lengend Snippet: Multimodal time series of a tickle response. Time series of four physiological measures, shown exemplarily for one trial after tickling of the most ticklish body part (here, armpit) of participant 1. Data in all panels are shown relative to touch onset (dashed line). ( a ) Facial action unit AU12 (lip corner pull, blue trace) and AU06 (cheek raiser, purple trace). Video stills show the facial expression of the participant in that trial at the time of touch onset (left) and at the peak of the response at 0.86 s after touch onset (right). ( b ) Thoracic circumference. ( c ) Spectrogram of vocalization. Response latencies (solid vertical lines) were computed using the Matlab function findchangpts to find the most significant change points in mean and slope of individual traces within 1 s time-interval post touch onset.
