Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Adolescents have adult-level beta power in dlPFC but reduced FEF alpha power and reduced dlPFC/FEF cross-frequency coupling during the antisaccade preparatory period. → Constantinidis Christos 2019

q2 · i? · review · r2
The review reports a developmental MEG study of the antisaccade preparatory period, citing Hwang, in which oscillatory differences corresponded with performance; alpha rhythms are described as supporting inhibitory dampening of neuronal activity.
"Adolescents showed adult level beta-band power in dlPFC but lower Frontal Eye Field (FEF) alpha-band power (Fig. 3A) and beta/alpha dlPFC/FEF cross-frequency coupling (Fig. 3G)."
Discussion¶
Related Claims¶
- In the one longitudinal fMRI study, dorsolateral prefrontal engagement reached adult levels by adolescence while dorsal anterior cingulate engagement continued increasing and mediated behavioral improvement — related
- Adolescent anticipatory alpha-band activity lacks the adult-like lateralized suppression pattern, instead showing higher right-parieto-occipital alpha and stronger modulation for cue-left than cue-right — related
- Impending rewards improve adolescent antisaccade performance toward adult levels, accompanied by greater nucleus accumbens activation — related
- Monkey neurophysiology shows adolescent-to-adult antisaccade improvement reflects enhanced representation of the goal and vector inversion, not stronger filtering of the stimulus — related
- Preparatory-period baseline activity before the antisaccade stimulus is higher and ramps faster in adult monkeys and predicts correct trials — related
- Acute exercise increases cortical delta, theta, alpha, and beta EEG power, with a moderately large effect size of 0.38 to 0.75 standard deviations — related
