Figure 4.

Comparison of the task‐specific modulation of neural connectivity based on a both anatomically and functionally constricted module (refer to Fig. 2). A: Horizontal tongue movement; B: Reading aloud of pinyins without semantics (e.g., ji, xi); C: Reading aloud of pinyins with semantic meaning [e.g., xiao(3) niao(3), meaning little bird]; D: Reading aloud of Chinese orthographic characters [e.g., , meaning clock]; E: Silent reading of Chinese orthographic characters [e.g., , meaning table]; F: Silent reading of pinyins of semantics [e.g., da(4) xiang(4), meaning elephant]. The strength of ROI‐based functional connectivity was labeled by a number (normalized to a reference, i.e., the covariance between M1 and Br during the tongue movement task) and weighted by lines: (1) solid black (or gray) lines indicate the covariance above a significance level (P < 0.05, N = 6 × 2 = 12) and larger (or less) than the reference; (2) dashed lines indicate the covariance below the significance level. Note that F shows the covariance at the right side of brain, since the brain activation during silent reading of Chinese characters was primarily localized at the non‐dominant side.
