HUMAN BRAIN MAPPING: Reading network development in elementary school has strong plasticity

Elementary education is an incubator for learning academic skills and helps children become educated, sociable and independent
.
In this learning stage, the brain will undergo non-linear and regional changes, but the relationship between these changes and academic performance such as reading ability is unclear

Considering the overall head growth, the changes in brain structure are quantified by directly calculating the local morphological difference between the brain images at two time points

(a) In the early (TP1-TP2) and advanced (TP2-TP3) stages of reading, the scale factor of the test-retest data (DKI-sample) is not significantly different from 1, but the scale factor of the DYSCO sample is less than 1.

The difference indicates that the head has a significant growth in each reading stage

When using this method to study typical cortical development, it was observed that the left temporal and temporal parietal regions belonging to the reading network showed an increase in the early reading stage, and showed stability in the late reading stage

Children with typical reading skills have the average brain volume change percentage (PBVC+scaling) of each cortical gray matter area in the early primary reading stage (n=23) and advanced reading stage (n=20)

The development of the cortex of the right inferior frontal gyrus and cingulate gyrus in children with dyslexia (DR) is different from that of the typical reader (TR)

(A) The cortical development patterns of DR and TR are different, located in the right tectal and cingulate gyrus isthmus

The linear regression model showed that dyslexia in early primary school had a positive effect on the percentage change in the volume of the right cranial gyrus (PBVC+Scaling) (TP1-TP2), and dyslexia in the late primary school had a positive effect on the percentage change in the volume of the right isthmic gyrus (PBVC+Scaling).
TP2-TP3) has a negative effect

Regarding the neural trajectory of children with dyslexia, it is observed that there is no difference in the gray matter development of the reading network on the left, while the neural trajectory of the right IFG cap layer (in the early reading period) and the right cingulate gyrus (in the late reading period) are different.
May reflect the compensatory neural mechanism

The current study obtained T1 MRI data at three time points to study the neurodevelopment of children with typical reading skills and children with dyslexia in the early and late stages of reading
.
Longitudinal PBVC with head growth and PBVC+ scaling can reliably measure the changes in the cortex over time
.
The results of the study show that in a typical brain development process, different regions develop together at a specific period in the primary school stage
.
Early reading is mainly manifested as an increase in the volume of the left temporal lobe (parietal) and a decrease in the volume of the occipital cortex; late reading is mainly manifested as an increase in the volume of the frontal lobe and a decrease in the volume of the occipital lobe and parietal lobe
.
This shows that in the first grade of elementary school, the reading network has greater plasticity, so this may prompt prevention and early intervention
.
In addition, outside the reading network, that is, the right IFG cap layer and the right cingulate gyrus isthmus, atypical neurodevelopmental trajectories related to dyslexia were found, which may represent a compensatory mechanism
