Exposure to retrieval cues improves retention performance and induces changes in ACTH and corticosterone release

Memory retrieval can be facilitated by pretest exposure to cues associated with the original training. The present series of experiments was aimed at investigating whether the effectiveness of the retrieval cues might be due to their emotional value and th ...

Making Retrieval Faster Through Document Clustering

David Grangier, Alessandro Vinciarelli

This work addresses the problem of reducing the time between query submission and results output in a retrieval system. The goal is achieved by considering only a database fraction as small as possible during the retrieval process. Our approach is based on ...

Prior exposure to a single stress session facilitates subsequent contextual fear conditioning in rats. Evidence for a role of corticosterone

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana

Previous studies showed that exposure of rats to chronic restraint stress for 21 days enhances subsequent contextual fear conditioning. Since recent evidence suggest that this effect is not dependent on stress-induced neurodegenerative processes, but to el ...

Post-training administration of a synthetic peptide ligand of the neural cell adhesion molecule, C3d, attenuates long-term expression of contextual fear conditioning

Maria del Carmen Sandi Perez

The neural cell adhesion molecule (NCAM) plays a key role in synaptic plasticity and memory formation. We have recently developed a synthetic peptide, termed C3d, which, through the binding to the first, N-terminal immunoglobulin-like (Ig) module in the ex ...

Glucocorticoid involvement in memory formation in a rat model for traumatic memory

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana

Contextual fear conditioning under training conditions involving high stressor intensities has been proposed as an animal model for traumatic memories. The strength of memory for this task has been related to the intensity of the conditioning stressor and ...

Experience-dependent facilitating effect of corticosterone on spatial memory formation in the water maze

Maria del Carmen Sandi Perez

Stress-related adrenal steroid hormones modulate brain and cognitive function. Electrophysiological studies, including primed burst potentiation and long-term potentiation, have indicated concentration-dependent inverted U-shape effects of corticosterone i ...
