Neural specificity of acupuncture stimulation at pericardium 6: Evidence from an FMRI study

Abstract

These findings may provide preliminary evidence for specific involvements of the cerebellar-hypothalamus and insula following acupuncture at PC6, which underlies the autonomic regulation of vestibular functions. The predominantly time-prolonged deactivations in these areas may also serve the clinical efficacy of PC6 in producing a sedative or tranquilizing effect in antiemetic treatment.
