Stellate ganglion radiation by polarized light (SGR) and placebo radiation were applied to healthy adults to compare the effects on the autonomic nervous system and electroencephalogram (EEG) of these radiations and the following results were obtained:<br>(1) The pulse rate tended to decrease during and after both SGR and placebo radiation. In contrast, the systolic blood pressure tended to increase during and after both radiations. No significant difference between radiations was found in either the pulse rate or systolic blood pressure. The coefficient of variation of the pulse rate (CV-PR), which reflects conditon of the cardiovascular parasympathetic nervous function, tended to increase during and after SGR and tended to decrease during placebo radiation. The value of CV-PR was significantly higher after SGR than after placebo radiation.<br>(2) The surface skin temperature of the lower extremities after SGR was slightly higher than that after placebo radiation, but the temperature of the upper extremities did not show any difference between SGR and placebo radiation.<br>(3) The relative power of alpha-2 wave as determined by quantitative EEG tended to be greater during and after SGR than during and after placebo radiation. The value 10min after SGR was significantly higher than after placebo radiation.<br>These results suggested that SGR activated the cardiovascular parasympathetic nervous function and relatively suppressed the cardiovascular sympathetic nervous function. We concluded that SGR influences not only the cardiovascular autonomic nervous system and surface skin temperature of the lower extremities, but also a wide range of EEG.
