Role of Hypothalamus in Acupuncture's Effects

The significant correlation between ancient medicinal practices and brain function marks a revolutionary frontier in the field of neuroscience. Acupuncture, a traditional oriental medicine, can affect brain regions, such as the hypothalamus, anterior cingulate, posterior cingulate, and hippocampus, and produces specific therapeutic effects, such as pain relief, suppression of hypertension, and alleviation of drug addiction. Among the brain regions, the hypothalamus, a small yet critical region in the brain, plays a pivotal role in maintaining homeostasis by regulating a wide array of physiological processes, including stress responses, energy balance, and pain modulation. Emerging evidence suggests that acupuncture may exert its therapeutic effects by modulating the activity of the hypothalamus and its associated neural circuits, particularly in relation to pain, stress, and metabolic regulation. Thus, we conducted a comprehensive review of past and current research on the role of the hypothalamus in mediating the therapeutic effects of acupuncture.
