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 …

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). In addition, power …

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 …

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.

Human hippocampal pre-activation predicts behavior

The response to an upcoming salient event is accelerated when the event is expected given the preceding events i.e. a temporal context effect. For example, naming a picture following a strongly constraining temporal context is faster than naming a …

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 …

Direct brain recordings reveal hippocampal rhythm underpinnings of language processing

Language is typically studied in isolation from memory. We demonstrate that the same neuronal computations used by the hippocampus for memory also subserve online language usage. These findings represent a major step in integrating the studies of language and memory, significantly expanding the role of hippocampal theta oscillations.

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 …
