Activation Maps. (A) Predicate Metaphors vs. Literal Motion Sentences demonstrating left angular gyrus activation at Ztal = 33mm, left inferior frontal gyrus (IFG) and left posterior middle temporal gyrus (pMTG) activation at Ztal = 7mm, left anterior middle temporal gyrus activation at Ztal = -15mm, and bilateral anterior middle temporal gyrus activation at Ztal = -26mm. (B) Literal Motion vs. Non-motive Sentences demonstrating bilateral calcarine deactivation at Ztal = 7mm, bilateral lingual deactivation at Ztal = -2mm, and bilateral anterior temporal lobe deactivation at Ztal = -15mm. (C) Predicate Metaphors vs. Non-motive Sentences demonstrating left pMTG activation at Ztal = 14mm, dorsal and posterior to the pMTG activation seen in the contrast of Predicate Metaphors vs. Literal Motion Sentences (Figure 3A). (D) Figurativeness Covariate for all three conditions demonstrating the same activation pattern as the Predicate Metaphors vs. Literal Motion Sentences contrast. All maps are plotted against the MNI single-subject standard brain with threshold t = 3.0 (p = .0051) and ceiling t = 5.5 (p < .0001), significant for clusters of voxels greater than 40. All maps include plausible sentences only and covariates for Naturalness, Plausibility, and Reaction Time. Surface maps were generated in Brain Voyager for visualization and orientation purposes.
