Abstract
An acupuncture (A.) therapist feels subtle changes of the finger tip sense during the Acupuncture treatment. Also the subjects feel the needle insertion as "Hibiki" (literally "resonance") which means hitting the A. point. Intellectual resonance (or synchronization) in human groups is reported. There is a possibility of resonance phenomenon between an A. therapist and a subject. Therefore the EEGs of an A. therapist and subject were measured. The EEGs of the therapist and subject changed according to differences in A. techniques, and a simultaneous resonance phenomenon was observed.
