BRAIN BUILDING BEATS · THE BEAT

Older-child brain illustrations

These educational graphics provide anatomical context for age-related research. Highlighting is an editorial selection, not measured activity, a growth rate or a developmental deadline. Other regions develop too. The surrounding email identifies each study and its relevant age range.

Presentation updated October 2026: neutral context, graphite canvas, muted-gold research highlights and Instrument Sans labels. Gold identifies selected anatomy, not measured activity or a distinct biological tissue class. Anatomical meshes, parcel selections and tissue anchors are preserved. Mobile uses separate transparent, closely framed renders without embedded labels.

Anatomy and modifications

Surfaces derive from M-CRIB 2.0 P01, a 16-day neonatal reference, by Alexander and colleagues, Murdoch Children’s Research Institute. Official atlas repository · Original labels · CC BY 4.0.

Changes: surface extraction and smoothing, illustrative affine and nonlinear shape registration to age-band T2 MRI templates, transparent materials, regional color, camera framing and labels. No artificial regional growth multipliers are applied. Each image is independently framed; its apparent size does not quantify growth.

What age registration means here

Shape references are MNI infant atlases and MNI pediatric atlases, McConnell Brain Imaging Centre, Montreal Neurological Institute, McGill University, obtained through TemplateFlow.

Registration fits a reference surface to a broad age-band MRI. It does not create an observed brain at each newsletter age. Whole-brain mask overlap was checked, but the transported regional boundaries and internal anatomy have not been validated in pediatric participants; they are approximate anatomical context, particularly across larger age differences. These models are not suitable for clinical use or measurement. Functional patches, language networks and hippocampal subfields in the cited studies are more specific than the highlighted atlas regions.

Newsletter stageShape-template bandSpecific limit
12–24 months17–21 monthsTemporal highlighting shows anatomical context for a broader frontal–temporal response; it is not an exact map of the study’s signal.
2–3 years27–33 monthsThe highlighted frontal folds locate the broader area measured with surface sensors; they are not a precisely isolated functional parcel.
3–4 years33–44 monthsThe highlight locates inferior prefrontal cortex. Surface measurements in a small study do not establish a deadline for rule switching.
4–5 years44–60 monthsThe whole hippocampus is shown for orientation; the fact concerns an internal compartment, not uniform growth of the entire region.
5–6 years54–102 monthsThe whole hippocampus is shown for orientation. Its internal compartments do not all change at the same rate.
6–7 years54–102 monthsThe highlight shows surrounding ventral temporal anatomy, not the exact word-selective patch. Timing follows reading instruction, not a birthday.
7 years and beyond84–132 monthsLanguage highlights show anatomical context for a wider functional network. The reference shape uses a 7–11-year MRI template; it is not an exact-age model of every older child.
