About this study
Official title: Auricular Press-Needle Acupuncture Induces Specific Brain Functional Reorganization and Modulates Autonomic Nervous Activity: A Randomized Sham-Controlled Trial
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 mechanisms in cognition and emotion. The findings provide a key theoretical and evaluative framework for translating aVNS into clinical applications for insomnia and depression.

Effect of Verum Auricular Acupuncture on Resting-State Brain Function in Healthy Subjects: A Functional Magnetic Resonance Imaging (fMRI) StudyDevice
The auricular points Heart, Kidney, Shenmen, and Subcortex were selected. After a baseline fMRI scan, sterile press needles were applied aseptically to these points in the experimental group.Each point was stimulated with 20 manual presses per session. This procedure was repeated for three sessions, separated by 10-minute intervals, resulting in a total intervention time of approximately 26 minutes. To capture immediate neural effects, a post-intervention fMRI scan was conducted to observe changes in brain activity.
The intervention involved applying auricular press needles (a type of intradermal embedding needle) to specific acupoints.
Sham Auricular Acupuncture as a Control Intervention for Brain fMRI Studies in Healthy VolunteersDevice
The sham auricular acupuncture control group was identical to the experimental group in terms of acupoint locations, auricular acupuncture procedure, and fMRI scanning protocol. The sole exception was that the sham group received a needle-free, auricular press needles.

What is being measured
The primary outcome is the main question the study is designed to answer.
Functional connectivity strength between the insula and the medial prefrontal cortex (MPFC)(T1-T0)
Data collection is divided into two stages:
Baseline : Collection of demographic data, baseline fMRI scan, and clinical assessment(T0).
post-intervention : fMRI scan and clinical assessment immediately after the intervention(T1).
The functional connectivity between the bilateral insula and medial prefrontal cortex was quantified by calculating the Pearson correlation of their mean time series at baseline and post-intervention. This connectivity strength serves as a proxy for the efficiency of information exchange between the interoceptive hub and the self-referential/emotion-regulatory hub. An increase following auricular acupuncture may reflect enhanced psychosomatic integration and top-down emotional regulation, suggesting a functional optimization of this circuit. Conversely, a decrease could indicate a disruption of pathological hyper-connectivity related to emotional constraint or an upregulation of control-mechanisms consistent with the observed alleviation of emotional symptoms
Measured: From enrollment to the end of treatment at 2 weeks
Secondary outcomes (4)
Local brain activity indicators:regional homogeneity (ReHo)(T1-T0)
Regional homogeneity (ReHo) was calculated as Kendall's coefficient of concordance between each voxel and its 26 nearest neighbors, assessed separately before and after the intervention. This metric captures the temporal synchrony of neural activity within local brain regions. Following auricular acupuncture, increased ReHo in regions such as the insula and prefrontal cortex may reflect improved neural coordination and functional integration. Conversely, decreased ReHo in specific areas could indicate a modulatory effect on abnormally elevated local synchrony.
Measured: From enrollment to the end of treatment at 2 weeks
Local brain activity indicators:amplitude of low-frequency fluctuation (ALFF)(T1-T0)
Amplitude of low-frequency fluctuation (ALFF) was quantified by calculating the square root of the power spectrum within the 0.01-0.08 Hz frequency band of the BOLD signal, followed by normalization to the global mean ALFF value. This metric reflects the intensity of spontaneous neural activity in the brain. An increase in ALFF within emotion- and cognition-related regions following auricular acupuncture may indicate an elevation in baseline neural activity or metabolic activity in these areas. Conversely, a decrease in ALFF in regions such as the limbic system could reflect an inhibitory modulatory effect of the intervention on hyperactivity, potentially contributing to emotional stabilization.
Measured: From enrollment to the end of treatment at 2 weeks
Local brain activity indicators:fractional amplitude of low-frequency fluctuation (fALFF)(T1-T0)
Fractional amplitude of low-frequency fluctuation (fALFF) was quantified by calculating the ratio of low-frequency ALFF to the full-frequency ALFF before and after the intervention, followed by normalization to the global mean fALFF value. Changes in fALFF following the intervention allow a more specific assessment of auricular acupuncture's regulatory effects on intrinsic neural oscillations related to cognition and emotion. When interpreted in conjunction with ALFF changes, the direction of fALFF alteration can help elucidate the specific mechanisms through which auricular acupuncture modulates neural activity patterns.
Measured: From enrollment to the end of treatment at 2 weeks
Interhemispheric coordination index: voxel-mirrored homotopic connectivity (VMHC)(T0-T1)
Voxel-Mirrored Homotopic Connectivity (VMHC) was assessed by calculating the Pearson correlation coefficient between BOLD time series from symmetrically corresponding voxel pairs in the left and right hemispheres, separately before and after the intervention. The VMHC value quantifies the functional coordination between homotopic regions across the two cerebral hemispheres. Following auricular acupuncture, enhanced VMHC in regions associated with emotional regulation and cognitive control, such as the prefrontal cortex and anterior cingulate cortex, may suggest improved interhemispheric balance and integration of emotional processing. Conversely, changes in VMHC within specific regions could help clarify how the intervention modulates functional imbalances between hemispheres, particularly those related to constrained emotional states.
Measured: From enrollment to the end of treatment at 2 weeks
