Researchers in artificial intelligence increasingly intervene on language models to study how their functions are organized, silencing weights and attention components in ways reminiscent of the brain lesions long used to map language in post-stroke aphasia. Under this program of mechanistic interpretability, a common...

The adult brain follows normative aging trajectories, yet stroke abruptly disrupts this process. Beyond the focal lesion, undamaged regions can deviate from expected aging due to diaschisis or pre-existing vulnerabilities, reflecting tissue health that may constrain recovery. Chronic post-stroke aphasia, a persistent l...

A specific brain aging phenotype is suggested as a potential intermediate pathway linking tau-related pathology to cognition prior to clinical impairment in cognitively unimpaired adults.

Two-stage models of grammatical encoding posit that sentence production unfolds in two sequential steps: the construction of a hierarchical syntactic structure, followed by its linearization into a sequence suitable for articulation. While widely accepted in psycho- and neurolinguistics, such models lack formal computa...
