Relations between sleep measures (Sleep amount and quality [PSQI total score]), intracortical myelin in the regions derived from the vertex-wise analysis (mid-posterior cingulate, middle temporal, and anterior OFC), and emotional behavior variables resulting from SEM modeling
| Sleep | P (sleep→myelin) | Myelin cluster | P (myelin→behavior) | Behavior |
|---|---|---|---|---|
| Sleep amount | 0.001 (+) | Mid-posterior cingulate | 0.503 | Anger |
| Sleep amount | 0.001 (+) | Mid-posterior cingulate | 0.062 | Fear |
| Sleep amount | 0.001 (+) | Mid-posterior cingulate | 0.956 | Positive affect |
| Sleep quality | 0.001 (−) | Middle temporal | 0.495 | Anger |
| Sleep quality | 0.001 (−) | Middle temporal | 0.2 | Fear |
| Sleep quality | 0.001 (−) | Middle temporal | 0.696 | Positive affect |
| Sleep quality | 0.001 (−) | Anterior OFC | 0.01 (−) | Anger |
| Sleep quality | 0.001 (−) | Anterior OFC | 0.53 | Fear |
| Sleep quality | 0.001 (−) | Anterior OFC | 0.007 (+) | Positive affect |
Statistically significant relations are in bold and the sign (+ or −) indicates the direction of the association (positive or negative, respectively).
