q3 i? FC between S1M1_L and Frontal_Mid_L showed a significant TIME × GROUP interaction, increasing after training only for the BCI-SRF group. → Yuan Liu 2024

q3 · i? · causal · r2

Seed-based whole-brain resting-state fMRI analysis with S1M1_L, SMA_L, S1M1_R, SMA_R seeds, compared across groups pre and post training. "A significant TIME × GROUP interaction effect was found in the FC between S1M1_L and Frontal_Mid_L", with significant between-group change at post (p = 0.0014).

"A significant TIME × GROUP interaction effect was found in the FC between S1M1_L and Frontal_Mid_L (Fig.3a and Supplementary Table 1) (F (1, 17) = 10.45,p = 0.0049). Post-hoc tests showed a significant increase after training only for the BCI-SRF group (Post vs Pre: p = 0.0041)"

Related Claims¶

• BCI-SRF training increased causal effects along the SM_cortex–cerebellar–thalamus loop and enhanced bidirectional frontal-parietal causal interaction relative to finger training — related
• Four specific sensorimotor connections showed significant TIME × GROUP interaction effects, with post-training increases only in the BCI-SRF group — related
• BCI-SRF training produces a substantially larger improvement in novel control-sequence accuracy than inborn finger training, with the BCI-SRF group's improvement 350% of the Finger group's — related
• Observational learning is associated with changed functional connectivity between V5/MT and sensorimotor areas, and pre-learning sensorimotor connectivity predicts subsequent learning gains — related
