Language neuroplasticity in brain tumour patients revealed by magnetoencephalography

Language impairment in brain tumour patients may be missed since standardised tests fail tocapture mild deficits. Neuroplasticity may also contribute to minimising languageimpairments. 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 …

The role of the uncinate fasciculus and inferior longitudinal fasciculus in healthy and disordered language production

The role of ventral fiber pathways in healthy and disordered language production

While neuroimaging research on language production has traditionally focused primarily on grey matter, several recent studies highlight the involvement of ventral and dorsal white matter pathways. A debated issue concerns the exact functional role of …

Language production in neurological populations

Investigating the Spatial and Temporal Components of Speech Production

The cognitive processes and neural mechanisms supporting language production have received considerably less research attention than those involved in language comprehension. This situation is partly attributable to the methodological challenges …

Roles of ventral versus dorsal pathways in language production: An awake language mapping study

Human language is organized along two main processing streams connecting posterior temporal cortex and inferior frontal cortex in the left hemisphere, travelling dorsal and ventral to the Sylvian fissure. Some views propose a dorsal motor versus …

Lexical selection with competing distractors: Evidence from left temporal lobe lesions

According to the competition account of lexical selection in word production, conceptually driven word retrieval involves the activation of a set of candidate words in left temporal cortex and competitive selection of the intended word from this set, …

Distributional analysis of semantic interference in picture naming

In picture-word interference experiments, participants name pictures (e.g., of a cat) while trying to ignore distractor words. Mean response time (RT) is typically longer with semantically related distractor words (e.g., dog) than with unrelated …

Lesions to Lateral Prefrontal Cortex Impair Lexical Interference Control in Word Production

Speaking is an action that requires control, for example, to prevent interference from distracting or competing information present in the speaker's environment. Control over task performance is thought to depend on the lateral prefrontal cortex …
