Background: For speakers with mild to moderate expressive aphasia the ultimate goal of aphasia therapy is to improve verbal functional communication, which may be assessed with the Amsterdam-Nijmegen Test for Everyday Language (ANELT; Blomert et al., …
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 …
Purpose: The three variants of primary progressive aphasia (PPA) differ in clinical presentation, underlying brain pathology, and clinical course, which stresses the need for early differentiation. However, brief cognitive tests that validly …
Parkinson’s Disease (PD) is a neurodegenerative disorder characterized by cardinal motor symptoms, including resting tremor, rigidity and bradykinesia, and cognitive impairments, such as deficits in executive function, attention and short-term …
Lemma representations are thought to map the meaning of words to their sounds and vice-versa (Levelt et al., 1999). There is evidence using different methodologies that suggests that lemmas are localised in the middle portion of the left middle …
Retrieval from semantic memory of conceptual and lexical information is essential for producing speech. It is unclear whether there are differences in the neural mechanisms of conceptual and lexical retrieval when spreading activation through …
Purpose: This systematic review focuses on the effect of bilateral Deep Brain Stimulation (DBS) of the Subthalamic Nucleus (STN) on language function in Parkinson’s Disease (PD). It fills an important gap in recent reviews, by considering other …
The cognitive architecture that allows humans to retrieve words from the mental lexicon has been investigated for decades. While there is consensus regarding a two-step architecture involving lexical-conceptual and phonological word form levels of …
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 …
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 …
