U.S., Jan. 13 -- ClinicalTrials.gov registry received information related to the study (NCT07332962) titled 'fMRI Evaluation of Auricular Acupuncture Targets: An Exploratory Clinical Study' on Dec. 13, 2025.
Brief Summary: This study employs resting-state functional magnetic resonance imaging (rs-fMRI) to examine whether auricular press needles acupuncture modulates functional connectivity between the insula and medial prefrontal cortex (MPFC), in a manner comparable to transcranial vagus nerve stimulation (taVNS), and to assess its association with interoceptive improvement. By establishing a neurophysiological baseline for auricular vagus nerve stimulation (aVNS) in the healthy brain, the research aims to clarify its regulatory mechanism...
