Stim/PreStim ratio response to stimulation strategies. Panel a. shows the individual response of each subject under every stimulation strategy. Columns represent each subject behavior; a different marker is used to identify each stimulation strategy. Markers under 100% line (grey dashed line) mean that the subjects decreased his/her tremor, while markers over the 100% line mean an increase in subjects tremor. Panel b. represents subjects behavior grouped by stimulation strategies. No significant differences were found between No Stim condition and the other stimulation strategies (paired samples t-test, P > 0.01). Notice that both panels use logarithmic scales in the Y axis.
