Fig. 4From: Acupuncture at KI3 in healthy volunteers induces specific cortical functional activity: an fMRI studyChanges of ALFF and ReHo values between real versus sham acupuncture at KI3 were calculated with paired t-test. The yellow color respects regions with higher ALFF and REHO values after real acupuncture at KI3 than sham acupuncture at KI3. The blue color respects regions with lower ALFF and REHO values after real acupuncture at KI3 than sham acupuncture at KI3Back to article page
