Parameters based on chemical shift indicate that methyl is a substituent with electron-withdrawing inductive effect and poor electron-donating conjugative effect. Perhaps its conjugative effect is on critical point. Methyl is electron-withdrawing for benzene relative to H. Otherwise, methyl has strong p-position and weak o-position orientation effect.

The neuropsychological research showed that left dorsolateral (BA8/9) prefrontal gyros showed greater activity during induction. But the research in the field is still very poor as so far, there is lot of deficiency. We all believe that the research in brain mechanism of inductive reasoning will have a good future.
