Dispelling the Plateau Assumption: Case-Based Evidence for Language Recovery in Chronic-Post Stroke Aphasia

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.

Hemispheric Fingerprinting: Identifying left and right hemispheres using functional connectivity

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.

Meaning for reading pseudowords: errors reveal semantic influences on pseudoword reading after stroke

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.

Simulating the spectrum, not the syndrome: Large scale individualized modeling of oral reading in stroke aphasia

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.

Dissecting the sublexical route for reading: Frontal and parietal networks support learned orthography-to-phonology mappings

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.

Meaning for reading: The neurocognitive basis of semantic reading impairment after stroke

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 organization of individually mapped structural and functional semantic networks in aging adults

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

Simulated attack reveals how lesions affect network properties in post-stroke aphasia

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.

Structural Disconnection of the Posterior Medial Frontal Cortex Reduces Speech Error Monitoring

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

Testing the perilesional neuroplastic recruitment hypothesis in aphasia

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.

Functional anomaly mapping reveals local and distant dysfunction caused by brain lesions

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.
