Abstract Prior literature has debated whether syntax is separable from semantics in the brain. Using functional magnetic resonance imaging and multi-voxel pattern analysis, our previous studies investigated brain activity during morpho-syntactic versus semantic processing. These only detected specialization activation patterns no syntactic 5- to 6-year-old 7- 8-year-old children. To examine if older children who have mastered skills would show for syntax, current study examined 64 9- 10-year-old using same design analyses. We observed that left IFG pars opercularis was sensitive but not information, supporting hypothesis this region serves as a core syntax. In addition, STG which been implicated integration of well MTG triangularis semantics, were both information with evidence specialization. findings suggest lexicalized view argues semantically regions are also critical processing language comprehension.

The ability to reason about the physical world is a critical tool in human cognitive toolbox, but nature of representations that mediate reasoning remains debated. Here, we use fMRI illuminate this question by investigating relationship between physical- system and two well-characterized systems: a) domain-general Multiple Demand (MD) system, which supports abstract reasoning, including mathematical logical b) language linguistic computations has been hypothesized some forms thought. We replicate prior findings network frontal parietal areas are robustly engaged identify an additional physical-reasoning area left cortex, also houses components MD systems. Critically, direct comparisons with tasks target systems reveal overlaps dissociable from it fine-grained activation patterns, replicates work. Moreover, does not overlap system. These results suggest rely on representations, nor exclusively domain- general supports.

Abstract Many artificial neural networks (ANNs) trained with ecologically plausible objectives on naturalistic data align behavior and representations in biological systems. Here, we show that this alignment is a consequence of convergence onto the same by high-performing ANNs brains. We developed method to identify stimuli systematically vary degree inter-model representation agreement. Across language vision, then showed from high-and low-agreement sets predictably modulated model-to-brain alignment. also examined which stimulus features distinguish high-from sentences images. Our results establish universality as core component provide new approach for using uncover structure computations.

The neural representations for compositional processing have so far been mostly studied during sentence comprehension. In an fMRI study of production, we investigated the brain speaking. We used a rapid serial visual presentation recall paradigm to elicit production from conceptual memory event. With voxel-wise encoding models, probed specificity structure built each sentence, comparing unstructured model word meaning without relational information with that encodes abstract thematic relations and event-specific structure. Whole-brain analyses revealed at different levels was encoded in large left frontal-parietal-temporal network. A comparison semantic structures composed comprehension same sentences showed similarly distributed activity patterns.
