The Neurobiology of the Lexical System: What kind of data is actually missing?

Sladjana Lukic, PhD

Compared to other animals, humans have developed a uniquely broad and highly
efficient lexical system. Studying the lexical system can be conceived as the
study of words, their structure, and their use. The distinct patterns of word
use might be indicative of its category (like noun or verb) and/or
subcategories (like transitive or intransitive verbs). An interesting test
case are words that, though highly productive in the English language, are
relatively understudied: a word that, free of any other context, could take
different meanings and belong to different categories (e.g., the brush and to
brush). Do word categories really exist? Can we find evidence that these word
categories are functionally dissociated and/or byproduct of online distributed
computations? How are such categories (or distributed computations)
instantiated neurally? At the moment, available empirical evidence seems to be
inadequate to fully address these questions. In an attempt to overcome each
single method limitations, I integrate a wide array of disciplines including
formal linguistics (which models can account for the word categories effects
observed), natural language processing (what words co-occurrence in text
reveals), and neuropsychology (how word categories are affected by brain
damage). In this talk, I will focus on studies investigating the lexical
system in healthy people and patients with focal and progressive brain
disorders. I will provide compelling evidence for the existence of
functionally and neurally dissociable lexical-semantic (i.e.,
semantic/thematic relations) and lexical-syntactic systems (i.e.,
morphosyntax, category conversion). This body of evidence will be instrumental
in redefining our understanding of the neurobiology of the lexical system..
