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, …
The left hemisphere (LH) is dominant for language in the majority of the healthy population. Patients with LH-damage may show global right-hemisphere (RH) activity for language. This makes interhemispheric transfer a good candidate for a brain …
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 …
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 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 …
Behavioral and classical electrophysiological methods (scalp EEG) provide important information about the timing of different processes involved in spoken word production, while functional Magnetic Resonance Imaging (fMRI) allows the localization of …
Primary progressive aphasia (PPA) is a neurodegenerative language disorder. Despite recent research, this disorder is studied less than vascular aphasia. There are three main accepted variants: nonfluent/agrammatic PPA (nfv-PPA), semantic PPA …
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 …
