In vivo evidence of neurophysiological maturation of the human adolescent striatum
Open accessAbstract
Maturation of the striatum has been posited to play a primary role in observed increases in adolescent sensation-seeking. However, evidence of neurophysiological maturation in the human adolescent striatum is limited. We applied T2*-weighted imaging, reflecting indices of tissue-iron concentration, to provide direct in vivo evidence of neurophysiological development of the human adolescent striatum. Multivariate pattern analysis (MVPA) of striatal T2*-weighted signal generated age predictions that accounted for over 60% of the sample variance in 10-25 year olds, using both task-related and resting state fMRI. Dorsal and ventral striatum showed age related increases and decreases respectively of striatal neurophysiology suggesting qualitative differences in the maturation of limbic and executive striatal systems. In particular, the ventral striatum was found to show the greatest developmental differences and contribute most heavily to the multivariate age predictor. The relationship of the T2*-weighted signal to the striatal dopamine system is discussed. Together, results provide evidence for protracted maturation of the striatum through adolescence.

Functional imaging studies indicate significant changes occur in the function of subcortical structures and in their relationship with cortical regions, notably in nuclei associated with reward and motivation.
“Functional imaging studies further indicate that significant changes occur in the function of subcortical structures and in their relationship with cortical regions, notably in nuclei associated with reward and motivation [26–29].”
From Adolescent nicotine exposure and persistent neurocircuitry changes: unveiling lifelong psychiatric risks (2025) · cites this paper as [28]
The Introduction reports fMRI evidence of age-related differences in striatal responses to reward, and the Results (Whole-brain analysis) identify developmental changes in the ventral striatum, a reward-related region. The Discussion (T2* and the adolescent brain) discusses frontostriatal development, but the passages do not establish changes in the functional relationship between subcortical and cortical regions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
