ERBB4 and schizophrenia: We believe that this expression pattern is plausible with the genetic association of NRG1 and ErbB4 with schizophrenia, since the limbic association cortices are crucially involved in many of the functions affected in the disorder, e.g. selection of the focus of attention and suppression of irrelevant stimuli, working memory, selection and change of strategies [60], [61].
