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 ...
Existing evidence indicates that 21-days exposure of rats to restraint stress induces dendritic atrophy in pyramidal cells of the hippocampus. This phenomenon has been related to altered performance in hippocampal-dependent learning tasks. Prior studies ha ...
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 ...
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 ...
Cell adhesion molecules (CAMs) involved in synaptic changes underlying learning and memory processes, are implicated in the effect of stress on behavioural performance. The present study was designed to test the hypothesis that (i) expression of CAMs is ap ...
