Left Anterior Negativity reflects distinct neural substrate for linguistic rule application

A critical issue for understanding language processing in the brain is whether linguistic rule application is subserved by a distinct neural substrate. Previous evidence based on electroencephalographic measurements is indirect because studies focus on neural changes after rule violation, which may reflect processes caused by the violation such as error handling. Here we show that correct rule-governed formations are associated with left frontal negative-going activity, providing direct evidence for rule application in the brain
