Prenatal exposure to a cannabinoid agonist produces memory deficits linked to dysfunction in hippocampal long-term potentiation and glutamate release.

To investigate the possible long-term consequences of gestational exposure to cannabinoids on cognitive functions, pregnant rats were administered with the CB1 receptor agonist WIN 55,212-2 (WIN), at a dose (0.5 mgkg) that causes neither malformations ...

Spatial working memory as an endophenotype for schizophrenia.

BACKGROUND: Spatial working memory impairments are among the neurocognitive deficits that may mark genetic predisposition toward schizophrenia. We previously reported that impairment on the spatial span subtask of the Wechsler Adult Intelligence ...

Enactment effect in memory: evidence concerning the function of the supramarginal gyrus.

Experimental behavioral data show that written action descriptions are remembered better when encoded by enacting them compared with merely verbal encoding. To explore this facilitating effect of encoding by performing actions (enactment effect), a ...

Targeting the CREB pathway for memory enhancers.

Today, the clinical notion of memory disorder is largely synonymous with Alzheimers disease. Only 50% of all dementias are of the Alzheimers type though, and dementias represent only the more severe of all learning/memory disorders that derive from ...

The mismatch negativity and reaction time as indices of the perceptual distance between the corresponding vowels of two related languages.

Two experiments were conducted to determine whether vowel familiarity affects automatic and conscious vowel discrimination. Familiar (Finnish) and unfamiliar (Komi) vowels were presented to Finnish subjects. The good representatives of Finnish and Komi ...

Age-dependent changes in the ability to encode a novel elementary motor memory.

In healthy individuals, motor training elicits cortical plasticity that encodes the kinematic details of the practiced movements and is thought to underlie recovery of function after stroke. The influence of age on this form of plasticity is incompletely ...

Alcohol hangover effects on memory functioning and vigilance performance after an evening of binge drinking.

The impairing effects on memory functioning after acute alcohol intoxication in healthy volunteers and after chronic use in alcoholics are well established. However, research determining the next-morning effects of a single episode of binge drinking on ...

Does infant memory expression reflect age at encoding or age at retrieval?

Do human infants express a memory acquired earlier in ontogeny in a manner appropriate to their age at encoding or their age at the time of retrieval? To answer this, we exploited the fact that retention is highly context dependent at 6 months but not at ...

Reinstatement maintains a memory in human infants for 1(1/2) years.

This study tested the proposition of Campbell and Jaynes (1966) that reinstatement is the mechanism by which early memories are maintained over a significant period of development. In four progressive replications, 6-month-old human infants learned to ...

Memory development in the second year: for events or locations?

We employed an object-placement/object-removal design, inspired by recent work on episodic-like memory in scrub jays (Clayton, N. S., & Dickinson, A. (1998). Episodic-like memory during cache recovery by scrub jays. Nature, 395, 272-274), to examine the ...
