Changes of eye-blink activities during hypnotic state.

Three experiments were conducted to examine eye-blink activity during the hypnotic state. The results were as follows: (1) eye-blink rate was dramatically reduced during the hypnotic as compared to the nonhypnotic state, (2) blink-rate variability between events (for example, the task and rest period) was smaller under the hypnotic than under the nonhypnotic state, (3) decrements, after induction of hypnosis, were observed in all aspects of blink-wave attributes (amplitude, duration, slope, and area). These findings can be interpreted in terms of the facilitation of motor inhibition by hypnosis.
