The neural mechanisms of language processing
and their relationship to executive function mechanisms

Evelina Fedorenko, PhD
Massachusetts Institute of Technology

There is a long tradition in psycholinguistics and cognitive neuroscience to
describe linguistic processes using domain-general cognitive constructs, like
storing information in and retrieving it from working memory, inhibiting
irrelevant information, selecting an option among alternatives, and predictive
processing. These kinds of mental operations may be implemented in
domain-general circuits of the fronto-parietal cognitive control or Multiple
Demand (MD) network, or in domain-specific brain areas that store the relevant
knowledge representations—the core fronto-temporal language-selective network.
In healthy adults, the core language network appears to do the ‘heavy
lifting’: activity in language but not MD regions ‘tracks’ linguistic input,
exhibits sensitivity to lexicalized and syntactic surprisal, correlates with
behavioral comprehension difficulty measures, and does not depend on the
presence of a secondary task. In tandem, this evidence suggests that the
engagement of the domain-general MD network during language processing in
neurotypical adults likely reflects effort associated with extraneous task
demands rather than core linguistic computations. However, recent behavioral
and neuroimaging studies have begun to suggest a possible role for the MD
network in recovery from aphasia, although the functional importance of this
engagement remains to be determined.
