Brain waves encode sentence structure and other cognitive functions

Author summary

Human language is a fundamental biological signal with computational properties that differ from other perception-action systems: hierarchical relationships between sounds, words, phrases, and sentences and the unbounded ability to combine smaller units into larger ones, resulting in a “discrete infinity” of expressions. These properties have long made language hard to account for from a biological systems perspective and within models of cognition. We argue that a single computational mechanism—using time to encode hierarchy—can satisfy the computational requirements of language, in addition to those of other cognitive functions.
