Oscillatory activity during maintenance of spatial and temporal information in working memory.
Working memory (WM) processes help keep information in an active state so it can be used to guide future behavior. Although numerous studies have investigated brain activity associated with spatial WM in humans and monkeys, little research has focused on the neural mechanisms of WM for temporal order information, and how processing of temporal and spatial information might differ. Available evi...
متن کاملRegional brain activity during working memory tasks.
The first aim of our PET study was to replicate previous findings concerning the brain areas activated by a verbal working memory task. The second aim was to specify the neural basis of the central executive, using a task of working memory updating. Our data confirm that the lower left supramarginal gyrus and premotor area are the key regions subserving short-term verbal memory processes. They ...
متن کاملBrain oscillatory correlates of working memory constraints.
It has been claimed that the coordination of neuronal oscillations differing in frequency is relevant for cognition. However, the validity of this claim has scarcely been investigated. Recent studies revealed that cross-frequency phase coupling and modulations of alpha-power dissociate between retention of relevant and suppression of irrelevant information in visual working memory (WM). We summ...
متن کاملOscillatory Brain Activity as underlying Neural Mechanism of Human Memory
It has been proposed that associative learning is accomplished by the formation of cell assemblies and synchronousactivity among the neurons of such an assembly. Induced gamma band responses (GBRs) and phase synchrony betweenelectrode sites are discussed as a signature of activity within a cell assembly. To examine the activation of this networkdue to memory recall, a paired associa...
متن کاملOscillatory brain activity in memory disorders
Neuronal oscillations are thought to underlie interactions between distinct brain regions required for normal memory functioning. This study aimed at elucidating the neuronal basis of memory abnormalities in neurodegenerative disorders. Magnetoencephalography (MEG) was used to measure oscillatory brain signals in patients with Alzheimer’s disease (AD), a neurodegenerative disease causing progre...
