Table 2. Grey matter volume correlations with sleep measures in community adolescents at age 16 using regions-of-interest.
| Sleep measure | Amygdala | Hippocampus | mPFC | |||
|---|---|---|---|---|---|---|
| T-value | Peak (x,y,z) | T-value | Peak (x,y,z) | T-value | Peak (x,y,z) | |
| Weekend wake up time | 3.51* | 21,-6,-12 | 3.11* | 2,42,-11 | ||
| 3.04* | -12,-3,-15 | |||||
| Weekend delay in wake up time | 3.23* | 20,-3,-12 | ||||
| 4.23** | 20,-25,-23 | |||||
* = p<0.05,
** = p<0.01,
*** = p<0.001 FWE corrected.
- = no significant results, Montreal neurological Institute coordinates are given for the voxel of maximal statistical significance; analyses are covaried for volume scale factor,age, and gender.
