Place selectivity in medial ventral temporal cortex
We recently quantified place-selective regions relative to cortical folding in human medial ventral temporal cortex. Traditionally referred to as the parahippocampal place area (PPA), we have found that this region is located within a particular anatomical location within the Collateral Sulcus. We cross-validated this location in 24 subjects across two studies in our lab, as well as 494 subjects from the Human Connectome Project and another 26 subjects from Nasr et al., 2014.

||Most probable location of place selectivity in CoS within the right hemisphere from 24 subjects.|
||Most probable location of place selectivity in CoS within the left hemisphere from 24 subjects.|
How to use:The label files have already been aligned to the FreeSurfer average surface (fsaverage).
Thus, the fastest and most accurate way to utilize these ROIs will be to to use cortex-based alignment in FreeSurfer to align your data to the fsaverage brain.
