Figures
- Fig 1.
Deaf versus hearing white matter and gray matter VBM. Threshold at T = 3.7 with extent threshold 100 voxels.
- Fig 2.
Cross-sections through the left superior temporal gyrus showing the focus of white matter deficit in the deaf group in relation to planum temporale and Heschl gyrus. A and B, crosshairs indicate the gray matter center of the planum temporale at (−60, −20, 10).12 C and D, crosshairs are centered on the gray matter center of Heschl gyrus at (−50, −20, 8).13 Talairach coordinates are transformed into MNI. The color bar represents the T score. “R” indicates right side of brain (radiology convention).
- Fig 3.
Asymmetry VBM of gray matter in deaf and hearing subjects. Threshold at T = 7.5, extent threshold at 400 voxels.
- Fig 4.
Asymmetry VBM of white matter in deaf and hearing subjects. T threshold at T = 7.7, extent threshold at 400 voxels.
- Fig 5.
Deaf versus hearing asymmetry VBM of white matter and gray matter. T threshold at T = 5.7, extent threshold at 200 voxels.
- Fig 6.
Deaf versus hearing asymmetry VBM of white matter viewed on coronal and axial cross sections. Crosshair at (−50, −18, 11). The color bar represents the T score.
