Subclaims¶

q3 i? Static inter-brain connectivity of FPC-rSTG was higher under BOTH and ONE than NO, but no significant differences were found for the static intra-brain network. → Xinyue Wang 2024

q3 · i? · causal · r2

Static analysis averaging FC/ISFC across the entire task period in the same 27-dyad experiment. The article reports that "the sISFC of FPC-rSTG was significantly higher under the‘BOTH’and ‘ONE’conditions than under the ‘NO’condition" but no static intra-brain differences were found.

"However, for the static intra- brain network, no signi ficant differences were found (Supplementary Table 9)."

Discussion¶

Related Claims¶

• State 1 of dynamic inter-brain connectivity is a superior communication state: higher global efficiency, clustering and ROI strength, lower path length, with ISFC increments in mirroring and mentalizing regions — related
• Fluid gestures accompany the superior intra-brain state (State 1) of the gesturing participant, whose occurrence rate correlates with fluency — related
• Behaviour locking shows interactive gestures accompany the superior inter-brain state (State 1), while the absence of gestures accompanies the inferior state under ONE — related
