Group analyses of brain regions in the early blind subjects.

|---|---|---|---|---|---|---|---|
| Cluster size (mm3) | P-values | x | y | x | |||
| 528 | <0.05* | −52 | −42 | −4 | 3.22 | L | Middle temporal gyrus |
| 840 | <0.01* | −48 | 24 | −4 | 3.64 | L | Inferior frontal gyrusa |

The threshold size of activation was P < 0.05, corrected for multiple comparisons, when the height threshold was set at Z > 2.58; x, y, and z are stereotaxic coordinates (mm). Hem, Hemisphere; L, left.

The search volume for activation was limited to each region activated by the sighted group.
