Prefrontal electrodes encode sentence-specific high-level semantics, shared between perception and rehearsal. (A) Reliability for shared electrodes during perception (sentence 2) and silent rehearsal that encode sentence-specific information for coherent (teal, Top) and incoherent (orange, Bottom) sentences. Weights from sentence 2 were applied to time courses from silent rehearsal. The solid black line indicates significance at q < 0.05 (FDR corrected across ROIs), and the dashed black line indicates significance at P < 0.05 (uncorrected). (B) Reliability scores for the four ROIs sharing sets of electrodes between sentence 2 and silent rehearsal. Reliability is shown for the three cases when the second repeat of sentence 2 was preceded by the same sentence 1 context (Same) or the different sentence 1 context from the same stimulus group (Different). As a control, we also computed reliability for when both sentence 1 and sentence 2 were drawn from a nonmatching stimulus group (Null). Differences from the null distribution are indicated by single asterisks, and differences between same vs. different contexts are indicated by lines, FDR corrected at q < 0.05 across all four ROIs and three tests performed in each of the conditions.
