EEG entropy during needle acupuncture. Box-plot illustration of alteration in state (SE) and response (RE) entropy values in nine healthy volunteers 2 min before (a), during ((b) immediately after applying the needles; (c) 2 min after (b); (d) 5 min after (b); (e) 10 min after (b); and (f) 15 min after applying needles), and 2 min after (g) needle acupuncture using two different acupuncture schemes (A and B). Note the significant decrease in entropy when using scheme A (sedation points). The horizontal line in the box indicates the position of the median. The ends of the bars define the 25th and 75th percentile and the error bars mark the 10th and 90th percentile. Modified from [27].
