The preliminary results show that the maximally evoked responses are at a deeper layer of the cortex. The value of this depth form surface of the cortex is about 900 m. A twodimensional recording was performed at this depth to find the responsive center or locus. The result shows that a dipole can be used to represent the responsive center with a coordinate of 1.9 mm posterial and 1.9 mm lateral to the Bregma. These finds should be valuable for further studies about pain.

The influence of position of the substitution, strength and number of donors and acceptors, and their coplanarity and asymmetry is discussed. The results indicate that the molecules may have larger first hyperpolarizabilities when the molecules have stronger and more donors and acceptors, large asymmetry of HOMO and LUMO, better coplanarity and higher accentricity. This work attemps at finding out the relationship between the structure and the property, thus providing theoretical basis for designing nonlinear optical molecules.
