Figure 4.

Functional and structural networks of the laryngeal motor cortex associated with production of syllable /ihi/. Functional connections (A) and probabilistic tractography (B) from both left and right hemispheric seed regions (marked as black circle) are presented on the inflated cortical surfaces; subcortical and cerebellar connections are shown on the series of axial images of a single subject in the standard space (p ≤ 0.05, corrected). For functional networks, color scale bar represents z-values, which reflect the strength of PPI connections, ranging from positive (red-yellow) to negative (light blue-dark blue). For structural networks, color scale bar illustrates the probabilistic distribution of structural connections expressed as the number of subjects (from 1 to 13 subjects) having a pathway pass through a given brain region.
