This study uses MEG to show that co-speech gestures reduce neural load in language regions before speech articulation, suggesting a linguistic rather than motoric role.

The paper investigates how the brain maintains and retrieves words during language comprehension, finding that memory is activity-silent and structured, with reactivation in specific brain regions.

The paper compares neural processing of object and action words using EEG, finding spatial and spectral differences in brain areas involved in word retrieval.

This study investigates how novel words activate semantic processing in the brain, finding that words with identifiable morphemes activate similar neural patterns as existing words.

This study investigates how bimodal divided attention affects cortical processing of linguistic context during speech perception in noise, finding reduced sentence-level representation under high cognitive load.

The paper shows that premotor cortex uses a compositional neural geometry to plan words by combining phoneme representations, enabling efficient planning of novel sequences.

The paper investigates the stability of language network responses across different tasks and compares it to the multiple demand network, finding robust language processing in the language network and task-dependent responses in the MD network.

This study investigates the neural mechanisms of singing and speaking by analyzing intracranial EEG data, revealing distinct sensorimotor dynamics during these behaviors.

The paper investigates whether tense and agreement processing dissociate in Arabic using ERPs, finding similar biphasic N400-P600 effects for both violations.

This study investigates whether combining gesture priming and neuromodulation improves verb retrieval in aphasia but finds no additive benefit, instead showing interaction effects.

This study decodes concept representations in aphasia using fMRI to generate continuous word sequences, showing that concept representations are largely preserved despite aphasia.

The paper shows that semantic features in word meaning are encoded in the brain through geometric structures similar to those in language models.

The paper investigates neural synchronization to linguistic structures and natural speech comprehension, finding that synchronization to phrases and sentences persists despite natural speech anisochrony.

This study identifies right-hemispheric language networks at single-neuron resolution in a patient with aphasia, showing task-specific encoding and functional organization.

This study examines how brain dynamics change with age during sentence generation, finding that older adults redistribute oscillatory activity and adopt a segmented processing strategy to maintain language abilities.
