The cerebellums of 12 rats were exposed under anesthesia. The spontaneous discharges of cerebellar neurons were recorded with glass microelectrodes. According to the request of the experimental designer to excite or inhibit the neuronal discharges, the qigong master emitted his qi with different mind power to the animal from a distance of 1-2 meters for 1-2 minutes. After the frequency of discharges was restored to the original level, the above procedure was repeated once or twice. An untrained person imitated the qigong master to give off his qi as a control.
The mean value of interspike interval was analyzed by a computer. The effects of the emitted qi were compared with that of the control group. 25 neurons were measured, 6 of which showed excitatory responses on the excitatory mind power of the qigong master. Their discharge frequencies increased. The mean interspike interval shortened from the original 84 ms to 16 ms (P<0.05). 8 neurons showed inhibitory responses to the inhibitory mind power of the qigong master. Their discharge frequencies decreased and the mean interspike interval increased from the original 12.6 ms to 211.6 ms (P<0.05) . 9 neurons showed a bidirectional response, i.e. both excitatory responses to the excitatory mind power and inhibitory responses to the inhibitory mind power. The mean interspike interval for the former shortened from the original 83.1 ms to 32.6 ms (P<0.05), and for the latter increased from the original 21.5 ms to 491.2 ms (P< 0.05) . 2 neurons, anyhow, showed no response to both kinds of intentions. In control experiments, the mimic qi did not cause any change.
The onset of neuron responses to the emitted qi was different in different neurons and could be divided into two patterns. One pattern was with rapid onset. The response appeared as soon as the qigong master entered the laboratory and became more intense during the action
of the emitted qi. The other type was with late onset. The response started 1-2 minutes after the beginning of the action of the emitted qi. Yet both types had a common characteristic of the after-effect. The response continued and lasted 12 minutes to 12 hours after the session of the emission of qi.
The results mentioned above indicate ( 1 ) The emitted qi is an objective biological message. ( 2 ) The effect of the emitted qi on the spontaneous discharges of the cerebellar neurons in rats varies. It can cause excitatory, inhibitory and bidirectional responses of the neurons. And these responses are controlled by the mind power of the qigong master. (3) There is a period of after-effect of the emitted qi on the discharges of the neurons after the cessation of the emission of qi.
