Table 2.
trGMcROI, cROItract and TSC values of cerebral and cerebellar cortical areas defined on functional bases.
| Structure | Functional Areas | trGM cROI (SD) (%) | cROI tract (SD) (%) | TSC(SD) |
|---|---|---|---|---|
| Cerebrum | Motor Area | 19(6) | 4.3(1.5) | 844(268) |
| Associative Area | 69(7) | 2.5(0.6) | 3865(864) | |
| Primary Somato-sensory | 4(2) | 3.4(2.1) | 267(154) | |
| Primary Visual Area | 6(2) | 1.1(0.6) | 446(160) | |
| Primary Auditory Area | 2(1) | 3.2(2.9) | 119(97) | |
| Cerebellum | Primary motor area | 2(1) | 2.5(1) | 1017(515) |
| Cognitive/Sensory Area | 96(1) | 25.6(2.3) | 5858(210) | |
| Sensory-Motor Area | 2(1) | 11.4(3.3) | 354(115) |
Each value is averaged over subjects. Data are expressed as mean (SD) for each area. Highest values are bold labelled. trGMcROI = GM tract volume in one cortical area relative to GM tract volume in all cortical areas; cROItract = GM tract volume in one cortical area relative to the area volume itself; TSC = total streamline count. Note: the TSC value exceeds 3000 streamlines because, for each parcellation, it is obtained averaging over subjects the results calculated adding left and right seeded streamlines together.
