Neuromagnetic cortical desynchronization during verbal fluency task

International Congress Series, 2005
Abstract Objective We aimed to investigate temporal and spatial dynamics of beta band desynchronization during verbal fluency task (VFT), which is known to reflect one of the frontal lobe functions. Method Ten healthy right-handed volunteers participated.

Reduced Prefrontal Oxygenation in Alzheimer Disease During Verbal Fluency Tasks

The American Journal of Geriatric Psychiatry, 2008
Near-infrared spectroscopy (NIRS) is an optical method to measure changes in the concentration of oxygenated hemoglobin (O(2)Hb) and deoxygenated hemoglobin (HHb) in the vascular system of the brain tissue. Because NIRS is easy to assess and does not have any side effects, it seems perfectly suitable for functional measurements in psychiatric patients ...

Cortical and subcortical influences on clustering and switching in the performance of verbal fluency tasks

Neuropsychologia, 1998
Impairments on lexical and semantic fluency tasks occur in both cortical and subcortical dementia. Recent reports that the average size of phonemic and semantic clusters is reduced in Alzheimer's disease (AD), but not in Parkinson's disease (PD) could support the hypothesis that in AD verbal fluency deficits arise from degraded memory storage while in ...

Attenuated Frontal Activation During a Verbal Fluency Task in Patients With Schizophrenia

American Journal of Psychiatry, 1998
Functional magnetic resonance imaging was used to study changes in cerebral blood oxygenation in schizophrenic patients during a verbal fluency task.Five right-handed male schizophrenic patients and five volunteers matched on demographic variables and verbal fluency performance participated in the study.
