Fig. 5: Dynamic tractography.
The video snapshots present the varying intensity of (a) co-growth of MI≥80 Hz & 0.5-1 Hz and (b) co-diminution of HFOHIL≥80 Hz at ages 1, 5, 10, and 20 years, as estimated by univariate regression analysis incorporating √age as an independent variable. Supplementary Movies 4–5 show the data across generations from 1 to 21 years. The brain images in this figure were created using FreeSurfer (https://surfer.nmr.mgh.harvard.edu/fswiki/CorticalParcellation). MI modulation index. MI≥80 Hz & 0.5-1 Hz denotes the strength of coupling between the amplitude of HFO≥80 Hz and the phase of slow-wave0.5-1 Hz. HFOHIL High-frequency oscillation defined by the Hilbert method.
