Brain-based classification of speech categories. (A) Searchlight brain classification maps of cross-task tone decoding and syllable-decoding. Voxel-level P < 0.005, cluster-level FWE-corrected P < 0.05. The left-side brain is right hemisphere and the right-side brain is left hemisphere. Upper panel, the whole-brain searchlight results of tone classification; middle panel: the searchlight results of syllable identity classification; lower panel, conjunction map of tone and syllable classification. (B) Anterior–posterior gradient of tone category and syllable identity representation in the LaSTG. Upper panel left, slice view of anterior–posterior separation from whole-brain searchlight analyses; Upper panel right, anatomical defined LSTG mask derived from the atlas of Automated Anatomical Labeling (AAL) (Tzourio-Mazoyer et al., 2002); Bottom panel, Dissociation between tone category and syllable identity classification performance in anatomical location (anterior vs. posterior STG). The left anterior STG was more sensitive to tone category than the left posterior STG. (C) Cross-talker whole-brain searchlight classification results (top panel) and conjuction with cross-task tone decoding results (buttom panel).
