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 ...

2003

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 ...

Effects of chronic stress on contextual fear conditioning and the hippocampal expression of the neural cell adhesion molecule, its polysialylation, and L1

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana

Chronic stress has been shown to induce time-dependent neurodegeneration in the hippocampus, ranging from a reversible damage to a permanent neuronal loss. This damage has been proposed to impair cognitive function in hippocampus-dependent learning tasks. ...

2001

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 ...

2000

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 ...

1998

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 ...
