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? Neuronal activity representing the correct eye-movement target is greater in adult monkey PFC, with the change localized in prefrontal rather than posterior parietal cortex. → Constantinidis Christos 2019

q2 · i? · review · r3
The review reports single-neuron recordings in monkeys performing the antisaccade task, citing Zhou, showing enhancement of goal and vector-inversion representations in adulthood while purely eye-movement-driven responses were similar across ages.
"The activity of neurons representing the location of where the eventual eye movement needs to be directed is greater in the PFC of adult animals [32]."
Discussion¶
Related Claims¶
- Preparatory-period baseline activity before the antisaccade stimulus is higher and ramps faster in adult monkeys and predicts correct trials — related
- Adolescents show adult-level dlPFC beta-band power but lower FEF alpha-band power and weaker dlPFC/FEF beta-alpha cross-frequency coupling during antisaccade preparation — related
- 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
- Antisaccade performance follows a curvilinear developmental trajectory best fit by an inverse function, with intra-subject latency variability decreasing with age — related
- Impending rewards improve adolescent antisaccade performance toward adult levels, accompanied by greater nucleus accumbens activation — related
- The ability to generate a single correct inhibitory response is evident early in development, while what improves through adolescence is the proportion of trials with correct inhibitory responses — a broader claim this one bears on
- Cognition is a transient phenomenon created by the functioning of distributed components of the nervous system — related
- Process-tracing measures should accompany outcome measures because process changes may not be immediately reflected in outcomes — a broader claim this one bears on
