Inhibitory effect of hippocampal 5-HT1A receptors on human explicit memory.

OBJECTIVE: Recent studies have indicated that the serotonergic (5-HT) system plays important roles in memory function. However, the specific relationship between 5-HT(1A) receptors and memory function is not clear in the human brain. To clarify this ...

Effects of risperidone on psychometric and cognitive functions in healthy elderly volunteers.

RATIONALE: Dementia includes not only cognitive deficit but may also include psychiatric and behavioral symptoms. These psychological symptoms of dementia require specific treatment without deleterious effects on cognitive functions. OBJECTIVE: The aim ...

Dissociations between implicit and explicit memory in children: the role of strategic processing and the knowledge base.

A review of the literature shows that explicit memory develops substantially from three years of age to adulthood, while implicit memory remains stable across this age range. Previously, this developmental dissociation has been attributed to different ...

Age differences and divided attention: is there a general deficit?

It was the goal of this study to determine whether there were age differences specifically associated with the ability to simultaneously execute two tasks, and whether cognitive costs correlated across different situations. Eighty-one young and 86 older ...

Implicit and explicit measures of memory for perceptual information in young adults, healthy older adults, and patients with Alzheimers disease.

In this study, we examined how implicit and explicit memory for perceptual information (modality and voice) and lexical information varied across three subject groups: healthy young adults, healthy older adults, and age-matched older adults with dementia ...

Serum cholesterol, precursors and metabolites and cognitive performance in an aging population.

The present study investigated if a causal relation exists between serum concentrations of precursors and metabolites of cholesterol and cognitive performance in a healthy aging population.Cognitive function addressing four domains of 144 individuals ...

Holding on to childhood language memory.

While early language experience seems crucial for mastering phonology, it remains unclear whether there are lasting benefits of speaking a language regularly during childhood if the quantity and quality of speaking drop dramatically after childhood. This ...

Sex-related impairment of memory for emotional events with beta-adrenergic blockade.

On the basis of recent evidence indicating a sex-related lateralization of amygdala function in memory for emotional events, together with substantial evidence suggesting hemispheric specialization in processing global (central) versus local (detail) ...
