<p>Developmental patterns of lag-1 temporal autocorrelation in HCPD.</p>

Listed in ZivaHub

<p>Lag-1 temporal autocorrelation (lag-1 TA) was estimated in HCPD as a complementary measure of intrinsic timescale. <b>(a)</b> Cortical map of lag-1 TA and relationship between whole-brain average lag-1 TA and age.

Description

Each data point in the scatter plot represents an individual participant (partial <i>R</i><sup>2</sup> = 0.008, <i>p</i><sub>anova</sub> = 0.03). <b>(b)</b> Region-wise GAMs identified heterogeneous age effects (i.e., partial <i>R</i><sup>2</sup>) across cortex.

FDR-corrected maps show regions with significant age effects (<i>p</i><sub>FDR</sub> < 0.05; 28.2% of regions with significant age effects). <b>(c)</b> Age effects on lag-1 TA were not significantly associated with the S–A axis. Significance of the association between age effects and S–A axis rank was assessed using 10,000 spin tests. <i>r</i><sub>s</sub> denotes Spearman’s rank correlation coefficient. Linear regression line is added for visualization purposes only. <b>(d)</b> Regional trajectories of developmental patterns of lag-1 TA were obtained from region-wise GAM results.

Each line corresponds to the model fit of each cortical region and is colored based on the region’s rank along the S–A axis.
