Brain correlates of HR responses to acupuncture. A: Difference map contrasting [HR+] – [HR−] demonstrated greater deactivation for HR− in PCL and DMN areas such as PC. Greater activation for HR+ events was noted in a parietal cluster consistent with poG/SPL. B: An intrasubject correlation analysis with HR− response found that compared with SH1, both SP9 and ST36 demonstrated greater significance in the correlation between HR deceleration and deactivation in DMN areas such as PCC, PC, and mPFC. Also, in comparison with ST36, SP9 stimulation produced greater significance in the correlation between HR− and right iPS activity. C: Greater DMN deactivation correlated with greater HR deceleration following verum acupuncture (SP9 and ST36) stimulation, as evidenced in a representative subject. n.b. iPS, intraparietal sulcus; poG, post‐central gyrus; SPL, superior parietal lobule.
