Brain regions responsible for word retrieval, speech production and deficient word fluency in elderly people: a PET activation study
A PET (positron emission tomography) activation study using word-fluency tasks was administered to i dentify the network for word retrieval and speech production, and to explore mechanisms for word finding difficulty observed in elderly people. It was found that the left anterior insula, as opposed to Broca’s area, left premotor area, the anterior cingulate gyrus, thalamus, basal ganglia, midbr...
متن کاملWhat do verbal fluency tasks measure? Predictors of verbal fluency performance in older adults
This study examined the contributions of verbal ability and executive control to verbal fluency performance in older adults (n = 82). Verbal fluency was assessed in letter and category fluency tasks, and performance on these tasks was related to indicators of vocabulary size, lexical access speed, updating, and inhibition ability. In regression analyses the number of words produced in both flue...
متن کاملVerbal memory and verbal fluency tasks used for language localization and lateralization during magnetoencephalography
OBJECTIVE The aim of this study was to develop a presurgical magnetoencephalography (MEG) protocol to localize and lateralize expressive and receptive language function as well as verbal memory in patients with epilepsy. Two simple language tasks and a different analytical procedure were developed. METHODS Ten healthy participants and 13 epileptic patients completed two language tasks during ...
متن کاملLexical-Semantic Search Under Different Covert Verbal Fluency Tasks: An fMRI Study
Background: Verbal fluency is a measure of cognitive flexibility and word search strategies that is widely used to characterize impaired cognitive function. Despite the wealth of research on identifying and characterizing distinct aspects of verbal fluency, the anatomic and functional substrates of retrieval-related search and post-retrieval control processes still have not been fully elucidate...
متن کاملCognitive or Cognitive-Motor Executive Function Tasks? Evaluating Verbal Fluency Measures in People with Parkinson's Disease
INTRODUCTION Executive function deficits are observed in people with Parkinson's disease (PD) from early stages and have great impact on daily living activities. Verbal fluency and oral diadochokinesia involve phonarticulatory coordination, response inhibition, and phonological processing and may also be affected in people with PD. This study aimed to describe the performance of PD patients and...
