The latest research in the field of acupuncture has revealed that this procedure can influence the brain’s attention sphere. Tests carried out by researchers on specific points, including the Taiyuan (Lu9) and Shenmen (Ht7), showed that the brain’s attention sphere was affected on a larger scale by the Ht7.

The research’s objective was to discover how the brain’s attention sphere reacted when needles where used on the Lu9 and Ht7 points of the body, thus providing information on how acupuncture stimulated the brain’s different functions and in what way these reacted to needle stimulation.

The event-related potentials (ERP) were tracked by using electroencephalography (EEG). Electroencephalography measures the brain’s activity, while the event-related potentials are measurements of the brain’s perception and thought responses, under the form of electrophysiological brain stimulating data.

Once the researches applied manual acupuncture on the Lu9 and Ht7 points, they checked whether there were any noticeable changes in the function of the brain’s reflecting cognitive, or P300. Another function that was tested was the brainwave, P3a, which measures how the brain reacts to changes in the environment. When acupuncture was carried out, both the P3a and P3b brainwaves were affected, the latter being another category of P300.

All information that is processed by the brain is measured in P3b, which also measures the perception of unlikely events that are out of the ordinary. The P3b brainwave’s measurement will reach its peak when the event is highly unlikely.

Chinese medicine has known the secret path to the brain through the acupuncture points Lu9 and Ht7 for over two thousand years now, which modern medicine nowadays, measures using EEG brainwaves. The Shenmen (Ht7) also known as the Spirits Gate, is an acupuncture spot located on the wrist that brings on a calming effect to the spirit and heart. People suffering from restlessness, depression, mania, disorientation, bad memory or palpitations find acupuncture in this spot effective for these conditions.

People suffering from lung ailments find the acupuncture spot Lu9 more beneficial, meaning that the Ht7 is more directly related to EEG measurements, for it is linked to cognition and attention brainwaves.
