| Research Abstract |
The ratio of patients with at-risk mental state (ARMS) was 15.9% in 157 first-visit patients (16-30 y.o) at psychiatric clinic or hospitals in Hokkaido. Biological motion perception, neural response in endogenous rule shifting, and neural oscillations during Sternberg task in schizophrenia patients were significantly different from normal controls, which suggests that these markers are useful as endophenotypes of schizophrenia.
