Effective Cerebral Connectivity during Silent Speech Reading Revealed by Functional Magnetic Resonance Imaging
Figure 3
Top panel: the directionally connected model for the SEM analysis on the effective connectivity during speech perception.
Note that a path from BA10→BA 22 was added because of this path loaded with the highest MI value (for details, see Materials and Methods). Middle panels: the estimated path coefficients, the standard errors of the mean (SEM), and the associated p-values (in parenthesis) in the /a/+/i/ non-target condition and the /o/ target condition. Statistically significant (p≤0.05) and insignificant (p>0.05) paths were rendered in solid and dashed lines, respectively. Bottom panel: pair-wise comparison of the path coefficients between target /o/ and non-target /a/+/i/ conditions. Statistically significantly (p≤0.05) and insignificantly (p>0.05) different paths were rendered in solid and dashed lines, respectively.
