Deqi Induction by HT7 Acupuncture Alters Theta and Alpha Band Coherence in Human Healthy Subjects

Figure 3

Coherence changes in the alpha band before and during HT7 acupuncture. Data show the difference between mean coherence during retention of the acupuncture needle and mean coherence before acupuncture. The green areas represented a decrease of coherence during the acupuncture treatment. The red areas mark an increase of coherence during the acupuncture treatment. Significantly increasing areas are marked with the yellow color ().
