Subclaims¶

q2 i2 White matter volume in the right cerebellum, particularly lobule 8, was reduced on day 2 compared with day 1 after SRT training, with no group × day interaction. → Olivo 2024

Evidence¶

Olivo 2024¶

Olivo, G., Persson, J. & Hedenius, M. (2024). Exploring brain plasticity in developmental dyslexia through implicit sequence learning. npj Science of Learning, 9:37. https://doi.org/10.1038/s41539-024-00250-w

q2 · i2 · causal · r1

Same longitudinal VBM analysis of the two-session SRT study in 17 DD and 18 TD children; the reduction reached "p FWE-corr = 0.001", "t = 4.98", "Cohen’s d = 0.617", and no group × day interaction on WMV was found.

"WMV was, on the other hand, reduced on day 2 compared with day 1 (p FWE-corr = 0.001, t = 4.98, Cohen’s d = 0.617) in the right cerebellum, particularly in the right lobule 8."

Discussion¶

Related Claims¶

• Group membership moderates the correlation between white matter volume of the left precentral gyrus and implicit sequence learning change, with a negative correlation in TD children but none in DD children — related
• General visuomotor skill learning on the SRT task occurs in both DD and TD children with no group difference — related
• Two SRT training sessions increase gray matter volume in right cerebellar lobule 8 in children regardless of dyslexia status — reports the opposite
