Perirhinal Cortex
Perirhinal cortex (area 35) is located in the parahippocampal gyrus. Perirhinal area 35 usually sits on the medial bank of the collateral sulcus but also on the lateral bank of the rhinal sulcus anteriorly, if the rhinal sulcus is present. Using high-resolution ex vivo imaging, we mapped perirhinal cortex (area 35) onto a surface template. Two different resolutions were collected 1) a "standard" 1 mm isotropic scan and 2) a high resolution 100 um isotropic scan. The high resolution scan showed architectural features (lamina and boundaries) while the standard 1mm scan provided the surface template that works with FreeSurfer. This perirhinal label was validated with histological staining and thus cytoarchitecturally-defined for perirhinal cortex (Brodmann's area 35).
