Do alpha and beta oscillations dissociate in context-driven spoken-word production?

Alpha- and beta-band oscillatory power decreases have been consistently found in spoken-word production, and localized to left lateral-temporal and lateral-frontal lobes (e.g., Piai et al., 2015; Roos & Piai, 2020). These oscillations have been …

Functional neuroanatomy of context-driven word retrieval: across-session consistency in fMRI

Functional magnetic resonance imaging (fMRI) is suitable for mapping the functional neuroanatomy of cognitive processes. However, mapping brain areas for specific tasks with fMRI does not necessarily guarantee validity, as activity profiles can vary …

Why we speak affects how we speak: electrophysiological signatures of word planning following verbal versus nonverbal material

It is unclear whether there are differences in the neural mechanisms of word planning when it arises after processing of verbal versus nonverbal material. Twenty participants took part in an EEG experiment where they completed verbal- and …

Across-session consistency of context-driven language processing: a magnetoencephalography study

Changes in brain organization following damage are commonly observed, but they remain poorly understood. These changes are often studied with imaging techniques that overlook the temporal granularity at which language processes occur. By contrast, …

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 …

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.

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 …
