Subcortical syntax: Reconsidering the neural dynamics of language

Subcortical contributions to core linguistic computations pertaining to syntax-semantics remain drastically under-studied. We critique the cortico-centric focus which has largely accompanied research into these higher-order linguistic functions and suggest that, while much remains unknown, there is nevertheless a rich body of research concerning the possible roles of subcortex in natural language. Although much current evidence emerges from distinct domains of cognitive neuroscience, in this review article we attempt to show that there is a clear place for subcortex in models of natural language syntax-semantics, including a role in binary set-formation, categorized object maintenance, lexico-semantic processing, conceptual-to-lexical transformations, morphosyntactic linearization, semantic feature-binding, and cross-cortical representational integration. In particular, we consult models of language processing relying on oscillatory brain dynamics in order to investigate both the apparent and possible functional roles of subcortex in language.

Automated summary

The subcortical contributions to core linguistic computations pertaining to syntax-semantics have received little attention. However, this article critiques the dominant focus on the cortex and highlights the rich body of research suggesting possible roles of the subcortex in natural language. The review shows that the subcortex can play a role in various aspects of language processing, such as binary set-formation, lexico-semantic processing, and cross-cortical representational integration.
