The lexical nature of alpha-beta oscillations in context-driven word production

In context-driven word production, picture naming is faster following constrained than neutral sentential contexts (e.g., “The farmer milked the… [picture]” vs. “The child drew a… [picture]”, followed by the picture of a cow), suggesting …

Transient perturbation of the left temporal cortex evokes plasticity-related reconfiguration of the lexical network

While much progress has been made in how brain organization supports language function, the language network's ability to adapt to immediate disturbances by means of reorganization remains unclear. The aim of this study was to examine acute …

Planning for language production: the electrophysiological signature of attention to the cue to speak

In conversation, speech planning can overlap with listening to the interlocutor. It has been postulated that once there is enough information to formulate a response, planning is initiated and the response is maintained in working memory. …

Speaking waves: neuronal oscillations in language production

Language production involves the retrieval of information from memory, the planning of an articulatory programme, and executive control and self-monitoring. These processes can be related to the domains of long-term memory, motor control, and …

Lesion evidence for a critical role of left posterior but not frontal areas in alpha-beta power decreases during context-driven word production

Studies suggest that alpha–beta power decreases index word retrieval in context-driven word production. We recorded the electroencephalogram from patients with stroke lesions encompassing the left lateral-temporal and inferior-parietal regions or left lateral-frontal lobe. Results indicate a critical role for the left posterior, but not frontal cortex, in generating the alpha–beta power decreases underlying context‐driven word production.

Neuroplasticity of language in left-hemisphere stroke: evidence linking subsecond electrophysiology and structural connections

Our understanding of neuroplasticity following stroke is predominantly based on neuroimaging measures that cannot address the subsecond neurodynamics of impaired language processing. We combined behavioral and electrophysiological measures and …

Withholding planned speech is reflected in synchronized beta-band oscillations

When engaged in a conversation, speakers sometimes have to withhold a planned response, for example, before it is their turn to speak. In the present study, using magnetoencephalography (MEG) outside of a conversational setting, we investigate the …

Beta oscillations reflect memory and motor aspects of spoken word production

Two major components form the basis of spoken word production: the access of conceptual and lexical/phonological information in long-term memory, and motor preparation and execution of an articulatory programme. Whereas the motor aspects of word …

Oscillatory brain responses in spoken word production reflect lexical frequency and sentential constraint

Two fundamental factors affecting the speed of spoken word production are lexical frequency and sentential constraint, but little is known about their timing and electrophysiological basis. In the present study, we investigated event-related …

Event-related potentials and oscillatory brain responses associated with semantic and Stroop-like interference effects in overt naming

Pictureword interference is a widely employed paradigm to investigate lexical access in word production: Speakers name pictures while trying to ignore superimposed distractor words. The distractor can be congruent to the picture (pictured cat, word …
