This study shows that language recovery in chronic post-stroke aphasia can continue for years, supported by neuroplastic changes, using longitudinal behavioral and fMRI assessments.

This paper uses supervised learning to classify brain hemispheres as left or right based on functional connectivity, achieving high accuracy in right-handed and left-handed participants.

This study examines language lateralization in older adults, finding it remains strongly left-lateralized and stable over time.

This study investigates how semantic and phonological processes contribute to pseudoword reading deficits in stroke patients, finding that both error types are influenced by distinct cognitive and neural mechanisms.

The paper introduces a dataset of reading behavior and multimodal MRI data from older adults to study normative reading patterns and brain-behavior relationships.

The paper develops individualized computational models of alexia by simulating phonological and semantic deficits in stroke survivors, showing strong correlations with measured deficits but also model limitations.

This study identifies neural networks involved in sublexical reading by analyzing lesion patterns in stroke patients, showing distinct roles for frontal and parietal regions in orthography-to-phonology mapping.

This study investigates semantic reading deficits after stroke, finding that impaired integration of semantic and phonological representations, particularly in the left posterior superior temporal sulcus, underlies these deficits.

The paper identifies individualized semantic networks in aging adults using fMRI and structural connectivity, revealing three modules related to semantic verbal fluency.

This study uses simulated attacks on brain networks to assess how stroke lesions affect network properties and aphasia severity, finding that global network measures explain some variance in aphasia symptoms beyond lesion volume.

The paper investigates how structural disconnections in the posterior medial frontal cortex affect speech error monitoring in post-stroke aphasia patients.

This study examines how post-stroke bypasses in brain networks predict variance in language functions, finding that bypass length and overlap predict lexical production and auditory comprehension.

This paper tests the perilesional neuroplastic recruitment hypothesis in aphasia using fMRI tasks and finds no evidence for increased activity in perilesional tissue during recovery.

This paper introduces a method to map functional anomalies in the brain caused by lesions, identifying both local and distant effects on tissue function and behavior.

This paper shows that targeting individual-specific brain hubs with non-invasive brain stimulation disrupts cognition more than non-hub areas.
