The FosB/△FosB positive staining was detected in nucleus accumbens septum, tuberculum olfactorium and dorsal caudate putamen, without little cFos positive staining. The results indicate the expression of cFos and FosB/△FosB display the differences in area and intensity, and the area intensively expressing FosB/△FosB is more nearly coincide with the area related to schizophrenia. So FosB/△FosB is a better mark to research the pathogenesis of schizophrenia.
