Effects of transcranial magnetic stimulation over the left posterior superior temporal gyrus on picture-word interference

Word-production theories argue that during language production, a concept activates multiple lexical candidates in left temporal cortex, and the intended word is selected from this set. Evidence for theories on spoken-word production comes, for …

White matter hyperintensities at critical crossroads for executive function and verbal abilities in small vessel disease

The presence of white matter lesions in patients with cerebral small vessel disease (SVD) is among the main causes of cognitive decline. We investigated the relation between white matter hyperintensity (WMH) locations and executive and language …

A TMS investigation of left middle-MTG involvement in lemma access in speech production and comprehension

According to a prominent account, lemmas are abstract word representations that act as central relay hub for accessing conceptual, phonological, and syntactic representations linked to a word (Levelt et al., 1999). They are crucial for both speaking, …

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 …

fMRI evidence for shared lemma representations in speech production and comprehension

On a prominent account, lemma representations map the meaning of words to their sounds and vice-versa, and are shared across production and comprehension (Levelt et al., 1999). A meta-analysis of word production studies suggests that lemmas are …

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 …

Microstructural integrity of crucial white-matter tracts for category fluency in elderly with cerebral small vessel disease

Recent studies have suggested that language production abilities decline in patients with small vessel disease (SVD) a pathology that is one of the main contributors of cognitive impairment in older adults. The loss of microstructural integrity in …

The role of the basal ganglia in inflectional encoding: An fMRI study of producing the past tense

According to a prominent account of inflectional encoding (Pinker & Ullman, 2002), regular forms are encoded by a rule-governed combination of stems and affixes, whereas irregular forms are retrieved from memory while inhibiting rule application. …

Lexical selection and the (pre)supplementary motor area white matter system

The supplementary and pre-supplementary motor areas (SMA and pre-SMA) has been suggested as involved in language processing since the early ages of electrical stimulation mapping. However they received far less attention in this sense than the …
