A parametric manipulation of factors affecting task-induced deactivation in functional neuroimaging.
Task-induced deactivation (TID) refers to a regional decrease in blood flow during an active task relative to a "resting" or "passive" baseline. We tested the hypothesis that TID results from a reallocation of processing resources by parametrically manipulating task difficulty within three factors: target discriminability, stimulus presentation rate, and short-term memory load. Subjects perform...

15 صفحه اولDoes “Task Difficulty” Explain “Task-Induced Deactivation?”
The "default mode network" is commonly described as a set of brain regions in which activity is suppressed during relatively demanding, or difficult, tasks. But what sort of tasks are these? We review some of the contrasting ways in which a task might be assessed as being difficult, such as error rate, response time, propensity to interfere with performance of other tasks, and requirement for t...
متن کاملDeactivation Network of Working Memory in Schizophrenia: Functional MRI Study with Parametric Digit n-back Task
Background and Purpose Working memory (WM) deficits plays an important role in cognitive deficits of schizophrenia. Task induced deactivation (TID) recently became the focus of fMRI study. This study aimed to explore TID network with fMRI and parametric digit n-back working memory task, and to explore the neural substrates of working memory impairment in high-performance schizophrenia. Methods ...
متن کاملA Short History of Statistical Parametric Mapping in Functional Neuroimaging
The history of human brain mapping is actually much shorter than one might have anticipated on entering the field. The first brain activation studies harnessed the ability to take images of brain function, successively within the same scanning session. This was facilitated by the use of short half-life radio tracers using Positron Emission Tomography (PET). These techniques became available in ...
