1. It is known that emitted qi alters the EEG and the cortical evoked potentials in man in our previous studies. In order to exclude the psychological influence when the emitted qi is applied to man, we carried out the experiment in the anesthetized cats and observed the effects of the emitted qi on the ABER and MLR.

2. The ABER was significantly facilitated and the peak latency prolonged in 10 out of 12 cases when the emitted qi was applied to the cats. The component of ABER consisted of 5-7 waves Which reflected the activities of the brainstem in different levels. Wave I originated from the acoustic nerve, Wave II from the cochlear nucleus of the medulla, Wave III from the superior olivary complex of the pons, Wave IV from the inferior colliculus of the mesencephalon, Wave V from the counterlateral inferior colliculus, and Waves Vl and Vll from the levels above the mesencephalon, or mainly from the hypothalamus in cats. The emitted qi could facilitate the IVth to Vllth waves of the ABER and prolonged the peak latency. It proved that the activities of the brainstem, especially the part above the mesencephalon, were increased but the conductive velocity between the nuclii of the brainstem was decreased.

3. The amplitude of the ABER was significantly inhibited and the peak latency prolonged from Wave IV to Wave Vl in 2 out of 12 cases when emitted qi was applied to the cats. It indicated that the effects of the emitted qi not only facilitated but also inhibited the activities of the brainstem above the mesencephalon. It explains the fact that the emitted qi may regulate the activities of the internal organs through changing the functional behavior of the brainstem.

4. The emitted qi facilitated the MLR in 6 cases and inhibited MLR in another 6 cases. The MLR is the primary component of the acustic cortical evoked responses, indicating the active level of the primary acoustic cortex. The emitted qi is similar to ABER but not all the same.

5. These results in our present research has provided an animal experimental foundation for studying the neuromechanisms when the emitted qi is applied to the subjects.
