Abstract

Volumetric studies have consistently shown reductions in cerebral gray matter volume between childhood and adolescence, with the most dramatic changes occurring in the more dorsal cortices of the frontal and parietal lobes. The purpose of this study was to examine the spatial location of these changes employing methods typical of functional imaging studies. T1-weighted structural MRI data (1.2 mm) were analyzed for nine normally developing children and nine normal adolescents. Validity and reliability of the tissue segmentation protocol were assessed as part of several preprocessing analyses prior to statistical parametric mapping (SPM). Using SPM96, a simple contrast of average gray matter differences between the two age groups revealed 57 significant clusters (SPM[Z] height threshold, P<0.001, extent threshold 50, uncorrected). The pattern and distribution of differences were consistent with earlier findings from the volumetric assessment of the same subjects. Specifically, more differences were observed in dorsal frontal and parietal regions with relatively few differences observed in cortices of the temporal and occipital lobes. Permutation tests were conducted to assess the overall significance of the gray matter differences and validity of the parametric maps. Twenty SPMs were created with subjects randomly assigned to groups. None of the random SPMs approached the number of significant clusters observed in the age difference SPM (mean number of significant clusters = 5.8). The age effects observed appear to result from regions that consistently segment as gray matter in the younger group and consistently segment as white matter in the older group. The utility of these methods for localizing relatively subtle structural changes that occur between childhood and adolescence has not previously been examined.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Changing cortical volumes over the adolescent age range are most prominent in the frontal and parietal lobes.

    “Interestingly, changing cortical volumes over this age range are most prominent in the frontal and parietal lobes.8, 58, 59”
  • In an MRI study comparing children of average age 9 and adolescents of average age 14, older children had higher white matter volume in frontal and parietal cortex, while younger children had higher grey matter volume in the same regions.

    “The results showed a higher volume of white matter in the frontal cortex and parietal cortex in the older children than in the younger group.The younger group, by contrast, had a higher volume of grey matter in the same regions.”
  • Absolute prefrontal cortex volume declines during adolescence in both humans and rats.

    “absolute PFC volume declines during adolescence in both humans (Sowell et al., 2001; Sowell et al., 1999) and rats (van Eden et al., 1990).”

    From Impulsivity, frontal lobes and risk for addiction (2009) · cites this paper as Sowell et al., 1999

  • Grey matter density in the frontal and temporal lobes follows an inverted-U shaped pattern of development.

    “Grey matter density in the frontal and temporal lobes has been reported to follow an inverted-U shaped pattern of development, peaking around puberty onset in the frontal lobe (age 11 in girls and 12 in boys), and at around 16–17 years in the temporal lobe.”
  • Frontal lobe grey matter density peaks around puberty onset (age 11 in girls and 12 in boys).

    “peaking around puberty onset in the frontal lobe (age 11 in girls and 12 in boys)”

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.
