Beyond Needling: Integrating a Bayesian Brain Model into Acupuncture Treatment.

Area of Science:

• Neuroscience
• Cognitive Science
• Integrative Medicine

Background:

• Acupuncture involves stimulating acupoints with needles, inducing sensations like de-qi.
• The perception of acupuncture extends beyond physical needling to include cognitive and affective elements.

Purpose of the Study:

• To explore the cognitive and affective aspects of acupuncture perception using a Bayesian perspective.
• To propose that acupuncture perception is a result of predictive coding, integrating sensory signals with prior expectations.

Main Methods:

• Adopting a Bayesian framework to analyze acupuncture perception.
• Applying principles of predictive coding and active inference to model the integration of sensory input and top-down predictions.
• Developing a perception-based Bayesian model of acupuncture.

Main Results:

• Acupuncture perception is framed as a probabilistic, inferential process driven by the brain's predictive coding.
• Individual perception of acupuncture arises from integrating prior experiences and expectations with incoming sensory signals.
• Cognitive factors significantly influence individual responsiveness to acupuncture treatment.

Conclusions:

• A Bayesian framework and predictive coding can elucidate and quantify the cognitive components of acupuncture.
• Understanding the cognitive aspects of acupuncture can explain differential treatment effectiveness among individuals.
• Acupuncture's healing process is influenced by belief and hope, supported by a complex interplay of cognitive factors.
