From: The interplay of sensory feedback, arousal, and action tremor amplitude in essential tremor

Single trial data of an exemplary participant. (a) The time course of the pupillometry is shown. (b) Single trial spectra of the force tremor per epoch. (c) Example of a participants single trial raw force data. Time courses are split per feedback type and feedback condition. One trial in the auditive only feedback conditions shows a stronger deviation to the target force, compared to other trials.
