Figure 1.
Statistical map showing brain activations for the contrasts communicative relative to strategic reasoning and control relative to strategic reasoning (random-effects analysis, FDR corrected).
Results demonstrate increased activations for communicative reasoning (with respect to strategic rationality) including prefrontal cortex (BA10) and precuneus. Strategic reasoning revealed less activation for prefrontal cortex (BA10) and precuneus compared with a control task. Areas of significant fMRI signal change are shown as color overlays on the T1-MNI reference brain. See text and Table 1 for details.

Statistical maps for conditions relative to resting baseline at MNI coordinates −42 −56 32.
Note increased BOLD responses for communicative reasoning and less activation during strategic reasoning.

Signal changes of BOLD response relative to rest (with standard errors) for left prefrontal cortex (BA10, −24 52 32), right insula (34 22 0), left STS (−52 −42 −2), and precuneus (22 −58 28) (contrast communicative reasoning relative to strategic reasoning).
