Modulation of hippocampal NCAM polysialylation and spatial memory consolidation by fear conditioning

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana

BACKGROUND: Cell adhesion molecule function is involved in hippocampal synaptic plasticity and associated with memory consolidation. At the infragranular zone of the dentate gyrus, neurons expressing the polysialylated form of the neural cell adhesion mole ...

Modulation of contextual fear conditioning by chronic stress in rats is related to individual differences in behavioral reactivity to novelty

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana

We investigated whether contextual fear conditioning could be related to the behavioral trait of locomotor reactivity to novelty in undisturbed and chronically stressed rats. Fear conditioning was found to be specifically enhanced in low reactive-stressed ...

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 ...

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 ...

Regulation of hippocampal cell adhesion molecules NCAM and L1 by contextual fear conditioning is dependent upon time and stressor intensity

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana

Cell adhesion molecules (CAMs) of the immunoglobulin superfamily, NCAM and L1, as well as the post-translational addition of alpha-2, 8-linked polysialic acid (PSA) homopolymers to NCAM (PSA-NCAM), have been implicated in the neural mechanisms underlying m ...

A role for brain glucocorticoid receptors in contextual fear conditioning: dependence upon training intensity

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana

We studied the possible involvement of corticosteroids in the establishment and long-term expression of contextual fear conditioning and questioned whether a corticosteroid action might be dependent upon stimulus intensity at training. Experiments included ...

Correlational relationship between shock intensity and corticosterone secretion on the establishment and subsequent expression of contextual fear conditioning

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana

A role for corticosterone in the consolidation of contextual fear conditioning has previously been proposed. In this study, physiological evidence was found to support this view. The extent of conditioned fear and the levels of plasma corticosterone in rat ...

Divertor target profiles and recycling studies in TCV single null lower standard discharges

Basil Duval, Yves Martin, Jean-Marc Moret, René Chavan, Xavier Llobet, Henri Weisen, Jonathan Bryan Lister, Richard Pitts, Roland Behn

A 'standard', single null lower diverted discharge has been developed to enable continuous monitoring of the first wall conditions and to characterise the effectiveness and influence of wall conditioning in the TCV tokamak. Measurements over a period encom ...
