The most critical attribute of human language is its unbounded combinatorial nature: smaller elements can be combined into larger structures based on a grammatical system, resulting in a hierarchy of linguistic units, e.g., words, phrases, and sentences. How the brain parses and represents such structures is a fundamental question in cognitive neuroscience. This study demonstrates that a hierarchy of neural processing timescales underlies grammar-based internal construction of hierarchical linguistic structure.
