Cytoarchitectonic parcellation and functional characterization of four new areas in the caudal parahippocampal cortex.

Brain areas at the parahippocampal gyrus of the temporal-occipital transition region are involved in different functions including processing visual-spatial information and episodic memory. Results of neuroimaging experiments have revealed a differentiated functional parcellation of this region, but its microstructural correlates are less well understood. Here we provide probability maps of four new cytoarchitectonic areas, Ph1, Ph2, Ph3 and CoS1 at the parahippocampal gyrus and collateral sulcus.
