TL;DR: Findings indicate that grammatical class per se is not an organisational principle of knowledge in the brain; rather, all the findings reviewed are compatible with two general principles described by typological linguistics as underlying grammaticalclass membership across languages: semantic/pragmatic, and distributional cues in language that distinguish nouns from verbs.

TL;DR: Event-related potentials (ERPs) effects lend support to the idea that reanalysis or repair processes after grammatical disagreement detection could involve more steps in the case of gender disagreement, as grammatical gender is a feature of the lexical representation in contrast to number, which is considered a morphological feature that combines with the stem of the word.

TL;DR: It is claimed that agreement processing is sensitive to both the type of feature involved and the constituents that express the agreement dependency, which indicates that rule-based computations of agreement dependencies are not blind to non-syntactic information but are often recruited to establish sentence-level relations.

TL;DR: The results reveal that highly proficient learners can show electrophysiological correlates during L2 processing that are qualitatively similar to those of native speakers, but the results also indicate the contribution of factors such as age of acquisition and transfer processes from first language to L2.

TL;DR: Just how well extant electrophysiological data comport with specific predictions of existing computational models is assessed and some suggestions for the kinds of research that can address some of the remaining open questions are offered.
