Granger Causality Analysis on ROIs from the resting-state FC results (SM_cortex integrating S1M1_R and SMA_L, thalamus, cerebellum, Frontal_Mid_L). "significant bi- directional increase of causal effect between the SM_cortex with the THA and frontal lobe" was found; SM_cortex to Cere also increased while Cere to SM_cortex decreased (p = 0.024).

"Compared with thefinger group, the BCI-SRF group showed significant bi- directional increase of causal effect between the SM_cortex with the THA and frontal lobe. (SM_cortex to THA: p = 0.01; THA to SM_cortex: p = 0.023; SM_cortex to Frontal:p = 0.02; Frontal to SM_cortex:p =0 . 0 1 5 )"

Related Claims¶

• BCI-SRF training increased functional connectivity between the left primary sensorimotor cortex and left middle frontal gyrus, and between right-hemisphere intrahemispheric and interhemispheric sensorimotor regions, relative to finger training — 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
• Four specific sensorimotor connections showed significant TIME × GROUP interaction effects, with post-training increases only in the BCI-SRF group — related
• Training sequence accuracy improved in both groups at Post, but only the BCI-SRF group retained a significant improvement at follow-up relative to Pre — 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
