The vote is on the link: is “The Giedd longitudinal neuroimaging study documented 15% prefrontal gray matter…” good evidence for the claim?

the evidence

The Giedd longitudinal neuroimaging study documented 15% prefrontal gray matter decline in healthy adolescents between ages 12-18.

Foundational developmental neuroscience research establishes that substantial volume reduction represents normal maturation.

the claim

Normal adolescent synaptic pruning reduces gray matter volume by 10-20% without pathology according to established developmental trajectories.

Physiological brain maturation necessarily involves substantial gray matter reduction as neural circuits refine and myelination increases.
