Memory, Short-Term

Oscillations in the alpha band (9-12 Hz) increase with memory load during retention in a short-term memory task.

To study the role of brain oscillations in working memory, we recorded the scalp electroencephalogram (EEG) during the retention interval of a modified Sternberg task. A power spectral analysis of the EEG during the retention interval revealed a clear ...

Functional equivalence of WAIS-III/WMS-III digit and spatial span under forward and backward recall conditions.

The purpose of the current study was to examine the performance characteristics of the Wechsler Spatial Span subtest in a mixed clinical sample. Contrary to expectation, differential patterns of performance were obtained on the Digit and Spatial Span ...

Delay modulates spectral correlates in the human EEG of non-verbal auditory working memory.

Studies using neuroimaging and electro- and magnetoencephalographic techniques have begun to identify the brain structures and dynamics that underlie auditory working memory. However, past research has not clearly characterized how the neural dynamics ...

The role of the parietal cortex in visual feature binding.

When multiple objects are simultaneously present in a scene, the visual system must properly integrate the features associated with each object. It has been proposed that this "binding problem" is solved by selective attention to the locations of the ...

Parahippocampal reactivation signal at retrieval after interruption of rehearsal.

Verbal information is maintained on-line within working memory by rehearsal. However, we still can recall the verbal information when rehearsal is interrupted. Here we show that this is achieved by reactivation of maintained information. We used ...

Specialization in the left prefrontal cortex for sentence comprehension.

Using functional magnetic resonance imaging (fMRI), we examined cortical activation under syntactic decision tasks and a short-term memory task for sentences, focusing on essential properties of syntactic processing. By comparing activation in these ...

Acute administration of citalopram facilitates memory consolidation in healthy volunteers.

OBJECTIVES: Decreasing serotonergic neurotransmission in humans has been found to impair memory consolidation. Such effects may be relevant to the memory deficits seen in major depression and the cognitive actions of antidepressant drugs used to treat ...

The Rey 15-item recognition trial: a technique to enhance sensitivity of the Rey 15-item memorization test.

Numerous publications on the Rey 15-item Memorization Test have cited limitations primarily in test sensitivity, as well as to some extent in specificity. In the current study, 49 patients with suspect effort, 36 neuropsychology clinic patients not in ...

The effect of retrograde and anterograde glucose administration on memory performance in healthy young adults.

Memory for a list of 20 words can be enhanced by preceding learning by consumption of 25 g of glucose, compared with consumption of an equally sweet aspartame solution (Psychopharmacology 137 (1998) 259; Psychopharmacology 157 (2001) 46). However, using ...

Distributed cortical systems in visual short-term memory revealed by event-related functional magnetic resonance imaging.

The spatio-temporal distribution of brain activity as revealed by non-invasive functional imaging helps to elucidate the neuronal encoding and processing strategies required by complex cognitive tasks. We investigated visual short-term memory for ...
