a trend toward significancep = .0702
After permutation testing, the AIC‐determined quadratic age relationships remained significant for the globus pallidus and thalamus bilaterally (left globus pallidus: p = .0133; right globus pallidus: p = .0201; left thalamus: p = .0026; right thalamus: p = .0058); however, for the striatum, while the left striatum demonstrates a trend toward significance (left striatum: p = .0702), the right striatum is no longer significant after permuting the model (right striatum: p = .166). 3.4.
