q2 i3 A main effect of group showed DD children had greater WMV than TD children in the left posterior thalamic radiation and inferior longitudinal fasciculus, particularly in the cuneus, at both assessment days. → 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 · i3 · associational · r2

Group contrast in the longitudinal VBM analysis of 17 DD versus 18 TD children; the comparison reached "p FWE-corr = 0.004", "t = 4.97", with "Cohen’s d = 1.404". The effect was present at both days.

"A main effect of group was also detected, with DD having greater WMV in the left posterior thalamic radiation and inferior longitudinal fasciculus (ILF) compared with TD, particularly in the cuneus (p FWE-corr = 0.004; t = 4.97; Cohen’s d = 1.404)."
