Acupuncture stimulation and neuroendocrine regulation

Area of Science:

• Neuroscience
• Integrative Medicine
• Physiology

Background:

• Acupuncture, a traditional Chinese therapy, is increasingly recognized globally.
• Its mechanism involves stimulating muscle afferent nerve fibers (A-δ and C-fibers).
• These signals modulate the central nervous system and visceral functions.

Purpose of the Study:

• To review the neuroendocrine and physiological effects of acupuncture stimulation.
• To examine acupuncture's impact on neuropeptides, hormones, and autonomic function.

Main Methods:

• Literature review of studies on acupuncture's effects.
• Analysis of research investigating neuropeptide and hormone release.
• Examination of studies on insulin sensitivity, immunomodulation, and autonomic nerve activity.

Main Results:

• Acupuncture influences the release of key neuropeptides and hormones (e.g., β-endorphin, serotonin, oxytocin).
• It modulates insulin sensitivity, immune responses (anti-inflammatory effects), and autonomic nerve activity.
• The process involves afferent signal transmission through the spinal cord to brain regions like the hypothalamus.

Conclusions:

• Acupuncture stimulation elicits complex neurophysiological responses.
• It impacts multiple systems, including the neuroendocrine, immune, and autonomic nervous systems.
• Further research can elucidate precise mechanisms for therapeutic applications.
