A Comparison Between the Current Seven Clusters and Subdivisions of the Inferior Parietal Lobule as Identified from Previous Works
| Our clusters | Mars and colleagues (2011) | Wang and colleagues (2012) | |
|---|---|---|---|
| Dorsal-anterior IPL (cluster 3) | PFta,b/hIP2c | Blue | Blue |
| Ventral-anterior IPL (cluster 2) | PFopa,b | Red | Green |
| Dorsal anterior-middle IPL (cluster 4) | PF1,2/PFma,b | Green/Blue | Light green |
| Ventral anterior-middle IPL (cluster 7) | PFcma,b/PFa,b | Green | Yellow |
| Lateral posterior-middle IPL (cluster 1) | PFma,b/PGaa,b | Green | Orange |
| Medial posterior-middle IPL (cluster 5) | hIP1c/PGaa,b | Yellow | Light green/yellow |
| Posterior IPL (cluster 6) | PGpa,b | Yellow | Red |

Caspers and colleagues (2006); bCaspers and colleagues (2008); cChoi and colleagues (2006); we did not observe a unique cluster that corresponds to PGa. Instead, PGa seems to be related to two clusters, including the lateral posterior-middle IPL (cluster 1, also including the PFm by cytoarchitectonics and close to Mars et al.'s green cluster and Wang et al.'s orange cluster) and medial posterior-middle IPL (cluster 5, also including hIP1 by cytoarchitectonics).
hIP1, human intraparietal area 1; hIP2, human intraparietal area 2.
