Tremor attenuation as function of the trial number. The plot shows how tremor attenuation computed with R
varied as more trials were performed, for all patients. Each marker represents a single trial, and the color of the marker corresponds to the severity of the tremor during this trial (before the NP was activated). The color scale is adjusted to the amplitude of each patient’s tremor, and represents trials with mild tremor as cold colors, and with severe tremor as hot colors (see colorbar in the plot). Patients are codified as follows: corresponds to patient 01, to patient 02, + to patient 03, ∘ to patient 04, â™¢ to patient 05, and △ to patient 06.
