A concise overview of the spatial and temporal underpinnings of lexical selection in spoken word production

Word production and comprehension both require mapping between the meaning, form, and syntactical representations of the word. We refer to the collective set of processes involved in performing this mapping as lexical selection. In the field of word …

The electrophysiology of language production

In the past decade, the well-established psycholoinguistics tradition of behavioural measures to study language production has been increasingly complemented with electrophysiological investigations. As a direct measure of net neuronal activity, the …

Time-course of right-hemisphere recruitment during word production following left-hemisphere damage: A single case of young stroke

Our understanding of post-stroke language function is largely based on older age groups, who show increasing age-related brain pathology and neural reorganisation. To illustrate language outcomes in the young-adult brain, we present the case of J., a …

Estimating the influence of stroke lesions on MEG source reconstruction

Source reconstruction of magnetoencephalography (MEG) has been used to assess brain reorganization after brain damage, such as stroke. Lesions result in parts of the brain having an electrical conductivity that differs from the normal values. The …

Are alpha and beta oscillations spatially dissociated over the cortex 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 …

Neural oscillations in the aging brain associated with interference control in word production

Speaking is not only about retrieving words and structuring them into sentences, but it also requires top-down control to plan and execute speech. In previous electrophysiological research with young-adult speakers, mid-frontal theta oscillations …

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, …

Language neuroplasticity in brain tumour patients revealed by magnetoencephalography

Language impairment in brain tumour patients may be missed since standardised tests fail to capture mild deficits. Neuroplasticity may also contribute to minimising language impairments. To address this possibility, we examined 14 patients with …

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 …
