Effects of high-frequency electromagnetic fields on human EEG: a brain mapping study.

Cell phones emitting pulsed high-frequency electromagnetic fields (EMF) may affect the human brain, but there are inconsistent results concerning their effects on electroencephalogram (EEG). We used a 16-channel telemetric electroencephalograph (ExpertTM), to record EEG changes during exposure of human skull to EMF emitted by a mobile phone. Spatial distribution of EMF was especially concentrated around the ipsilateral eye adjacent to the basal surface of the brain. Traditional EEG was full of noises during operation of a cellular phone. Using a telemetric electroencephalograph (ExpertTM) in awake subjects, all the noise was eliminated, and EEG showed interesting changes: after a period of 10-15 s there was no visible change, the spectrum median frequency increased in areas close to antenna; after 20-40 s, a slow-wave activity (2.5-6.0 Hz) appeared in the contralateral frontal and temporal areas. These slow waves lasting for about one second repeated every 15-20 s at the same recording electrodes. After turning off the mobile phone, slow-wave activity progressively disappeared; local changes such as increased median frequency decreased and disappeared after 15-20 min. We observed similar changes in children, but the slow-waves with higher amplitude appeared earlier in children (10-20 s) than adults, and their frequency was lower (1.0-2.5 Hz) with longer duration and shorter intervals. The results suggested that cellular phones may reversibly influence the human brain, inducing abnormal slow waves in EEG of awake persons.

A birdcage model for the Chinese Meridian System: part I. A channel as a transmission line.

The concept of Qi and the concept of channel are so closely related that they must be defined and comprehended simultaneously in a coordinated fashion. Once the nature of Qi is established in terms of physics, we may be able to explain the functional role that the channels play, as well as explain other Chinese medical terminology with a language of modem science. Based on the low electrical impedance characteristics of acupoints, we propose that the meridian channel is equivalent to an electromagnetic transmission line and the Qi is the electromagnetic (EM) standing wave riding on the line, with acupoints as its nodes. The standing wave within each segment of the channel separated by acupoints is in natural oscillation thus the segment may be analyzed as a lambda/4 open circuit that behaves like a series RLC resonator. Acupuncture until De Qi is effectively equivalent to charging the capacitor Ceq of the RLC resonator in the transmission line. The mechanism of bu and xie are charging or discharging the capacitor to bring the capacititive (or inductive) behavior of the segment back to that of the resonant state. Kirlian photograph may serve as a visual observation of the EM waves on channels.

[Keratin dielectric parameters in the millimeter wavelength range].

The specific density of human hairs, which are known consist essentially of keratin, was measured. Based on the data on the attenuation of millimeter radiowaves in hairs, the dielectric permeability of hairs was determined. Multiple reflections of waves at the boundary of the hair layer were into account.

[New therapeutic measures for the treatment of ulcers].

In this study we tested the effect of vibrating electromagnetic waves on both arterial and varicose ulcers. The two transmitters we used were the diatrom and the fel, which differ in the energy transmitted and the means of application (direct contact electrode for the fel, distance transmission for the diatrom). Out of 17 cases treated we obtained 15 cures. This proportion of positive results encountered in traumatology and in dermatology for cases where the vascular factor played an important role, makes it possible to consider the application of vibrating electromagnetic waves as a valid therapy for ulcers.
