Distinct neural processes link speech planning and execution

This paper identifies distinct neural mechanisms for speech planning and execution using intracranial recordings.

Multiple Nested Distributed Language Networks in the Human Brain

The paper identifies two nested language networks in the human brain using functional mapping across multiple cohorts, showing distinct roles in phonology and syntax.

Mapping of critical prosodic and phonetic networks in post-stroke apraxia of speech

The paper maps neural substrates for prosodic and phonetic speech motor coordination in post-stroke apraxia of speech using lesion-symptom mapping in a large cohort.

Cortical networks responsive to phrase structure and subject island violations

This study uses fMRI to compare brain activation patterns for two syntactic violations, finding distinct neural responses for phrase structure and subject island violations.

Verbal working memory and syntactic comprehension segregate into the dorsal and ventral streams

This study investigates the neural separation of verbal working memory and syntactic comprehension, finding distinct brain networks associated with each function.

The Wernicke conundrum revisited: evidence from connectome-based lesion-symptom mapping

The paper uses connectome-based lesion-symptom mapping to investigate word and sentence comprehension deficits in stroke patients, finding that middle-posterior temporal lobe regions, not double disconnection, are primarily responsible.

The Neuroanatomy of Speech Processing: A Large-Scale Lesion Study

This study investigates the neural basis of speech processing by analyzing lesion data from 158 individuals with brain damage, identifying key regions involved in syllable discrimination and word comprehension.

Functional differentiation in the language network revealed by lesion-symptom mapping

This study uses lesion-symptom mapping to identify functional differentiation in language network regions by analyzing aphasia patients with left hemisphere stroke damage.

Forward Entrainment: Evidence, Controversies, Constraints, and Mechanisms

This paper examines conditions under which forward entrainment is observed or not, reviews conflicting studies, and explores potential mechanisms.

Agrammatism and paragrammatism: a cortical double dissociation revealed by lesion-symptom mapping

This study uses lesion-symptom mapping to show a double dissociation between agrammatism and paragrammatism, linking them to distinct brain regions.

Network dynamics of Broca’s area during word selection

This study investigates network dynamics in Broca’s area during word production, finding parallel network interactions and specific inter-regional couplings during lexical retrieval and selection.

Neural organization of speech production: A lesion-based study of error patterns in connected speech

This study examines word error patterns in connected speech and object naming after left hemisphere stroke, finding distinct neural substrates for different types of paraphasias.

Prediction in Human Auditory Cortex

The paper identifies two distinct predictive mechanisms in human auditory cortex during speech perception and production, revealing their anatomical and functional roles in predicting 'when' and 'what' acoustic events occur.

The neurobiology of agrammatic sentence comprehension: a lesion study

This study examines agrammatic sentence comprehension by analyzing lesion data from 66 patients, finding that damage to superior temporal and inferior parietal regions, not Broca's area, is most strongly associated with impaired performance on noncanonical sentences.
