The parahippocampal region in schizophrenia

The parahippocampal region is an area of increasing interest in schizophrenia research. Most research on the parahippocampal region in schizophrenia has examined only the entorhinal cortex or the parahippocampal gyrus as a whole. Many still undiscovered changes may thus occur in other, less studied parts of the region. This chapter focuses on the parahippocampal gyrus and the entorhinal cortex within it. It leads us to speculate that schizophrenia is not simply a dysfunction of heteromodal association cortex, but also a dysfunction of the parahippocampal region. The region is functionally more complex than implied by its common designation as a paralimbic cortex.
