*3.1.1.3 The mode of smelling "Zuko" incense rubbing into the hands and putting the hands together*

**Figure 8** shows an example of MEG response for the mode of smelling "Zuko" incense rubbing into the hands with putting the hands together. In this case, a female subject A3 had the characteristic habit of putting the hands in daily life. **Figure 8a** shows also the result of response of a vector by single current dipole estimation method for smelling "Zuko" incense. **Figure 8b** shows also a vector of single current dipole estimated in the brain using 3-D coordinates.

**Figure 8a** shows the contour mapping of real-time MEG responses in the state of smelling "Zuko" incense rubbing into the hands with putting the hands together. The red curves show equivalent positive magnetic fields, and the blue curves show equivalent negative magnetic fields on the subject's head surface. A green arrow shows an estimated single current dipole obtained from these contour mappings by the computer.

From these estimations of **Figure 8**, we obtained the result of which a left orbitofrontal cortex (OFC) was activated by smelling "Zuko" incense with putting the hands together.

Next, **Figure 9** shows also another example of a different female subject B5 who had no habit with putting the hands in daily life. **Figure 9a** shows the result of response of a vector by single current dipole estimation method for smelling "Zuko" incense with putting the hands together. **Figure 9b** shows also a vector of single current dipole estimated in the brain using 3-D coordinates.

In this case, a left inner frontal area (F5 language region) was activated. She told that she had the especial impressions for the recall of a few words of the language on the praying when she smelled "Zuko" incense with putting the hands during this MEG experiment.

**Figure 10** shows the result of another example of MEG response for the mode of smelling "Zuko" incense rubbing into the hands with putting the hands together. In this case, a female subject A4 who had the habit of putting the hands in daily life hold the especial strong impressions of visual image of praying when she smelled "Zuko" incense with putting the hands during the MEG experiments.

**Figure 10a** shows the result of response of a vector by single current dipole estimation method for smelling "Zuko" incense with putting the hands together. **Figure 10b** shows also a vector of single current dipole estimated in the brain using 3-D coordinates. From these above estimations, a left occipital area (V1 visual region) in the brain was activated.

From these estimations we obtained the result of which a left occipital gyrus (V1 visual region) was especially activated by smelling "Zuko" incense without putting the hands together. This subject A3 had especial remember impressions of visual image for this "Zuko" incense because of her smelling "Zuko" incense with putting the
