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 …

Comparing human and chimpanzee temporal lobe neuroanatomy reveals modifications to human language hubs beyond the frontotemporal arcuate fasciculus

The biological foundation for the language-ready brain in the human lineage remains a debated subject. In humans, the arcuate fasciculus (AF) white matter and the posterior portions of the middle temporal gyrus are crucial for language. Compared with …

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 …

Corpus callosum involvement in language ability after left-hemispheric stroke

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 …

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 …

How the speed of word finding depends on ventral tract integrity in primary progressive aphasia

Primary progressive aphasia (PPA) is a clinical neurodegenerative syndrome with word finding problems as a core clinical symptom. Many aspects of word finding have been clarified in psycholinguistics using picture naming and a picture-word …

The functional neuroanatomy of the left temporal lobe white matter – an interdisciplinary approach based on intraoperative and comparative studies.

The left temporal lobe is claimed to be involved in language comprehension in both the classical (Wernicke, 1874) and contemporary dual-pathway models for language processing (Hickok & Poeppel, 2007, Roelofs, 2014), but the role of neuroanatomical …

Investigating the semantic control network and its structural decline in mild cognitive impairment and mild dementia

Although the episodic and semantic memory systems have long been studied separately, recent literature revealed shared neural substrates, including the medial temporal lobe (MTL). One important aspect of semantic memory is semantic control, which …

The frontal aslant white matter tract (FAT) and semantic selection in word production

The frontal aslant tract (FAT) is a white matter structure joining the anterior supplementary and pre-supplementary motor area (SMA and pre-SMA) to the inferior and middle frontal gyri. FAT shows leftward asymmetry (Catani et al., 2012), which …

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