Episodic and semantic memory in bilingual and monolingual children.

Although bilinguality has been reported to confer advantages upon children with respect to various cognitive abilities, much less is known about the relation between memory and bilinguality. In this study, 60 (30 girls and 30 boys) bilingual and 60 (30 ...

The effects of road traffic noise and meaningful irrelevant speech on different memory systems.

To explore why noise has reliable effects on delayed recall in a certain text-reading task, this episodic memory task was employed with other memory tests in a study of road traffic noise and meaningful but irrelevant speech. Context-dependent memory was ...

Lorazepam and scopolamine: A single-dose comparison of effects on human memory and attentional processes.

This placebo-controlled, double-blind, double-dummy, independent groups study directly compared effects of the benzodiazepine, lorazepam (2.0 mg/70 kg orally administered), and the anticholinergic scopolamine (0.6 mg/70 kg subcutaneously administered) on ...

Neural basis for semantic memory difficulty in Alzheimers disease: an fMRI study.

Patients with probable Alzheimers disease are thought to have a semantic memory deficit. We used functional MRI to evaluate the neural basis for impaired semantic memory for ANIMALS and IMPLEMENTS in 11 patients with Alzheimers disease and 16 healthy ...

Hippocampus and memory. Can we have our place and fear it too?

Theories of hippocampal function are often split into cognitive map theories and relational/episodic memory theories. In this issue of Neuron, show that hippocampal cells respond to the combination of spatial location and conditioned stimuli in a ...

Sleep, consciousness and the spontaneous and evoked electrical activity of the brain. Is there a cortical integrating mechanism?

The physiological mechanisms that underlie consciousness and unconsciousness are the sleep/wake mechanisms. Deep sleep is a state of physiological reversible unconsciousness. The change from that state to wakefulness is mediated by the reticular ...

The delivery rate of dietary carbohydrates affects cognitive performance in both rats and humans.

RATIONALE: Glucose is the main metabolic fuel of the brain. The rate of glucose delivery from food to the bloodstream depends on the nature of carbohydrates in the diet, which can be summarized as the glycaemic index (GI). OBJECTIVES: To assess the ...

Brain imaging of tongue-twister sentence comprehension: twisting the tongue and the brain.

This study used fMRI to investigate the neural basis of the tongue-twister effect in a sentence comprehension task. Participants silently read sentences equated for the syntactic structure and the lexical frequency of the constituent words, but differing ...

Preconscious defence analysis, memory and structural change.

Beginning with the ways in which the use of the couch lends depth to the surface (Erikson, 1954), I explore the topography of the inter- and intrasubjective psychoanalytic situation and process. I suggest that defences are not by definition unconscious ...

Memory traces unbound.

The idea that new memories are initially labile and sensitive to disruption before becoming permanently stored in the wiring of the brain has been dogma for >100 years. Recently, we have revisited the hypothesis that reactivation of a consolidated memory ...
