Footshock stress definition

WebIn a typical active avoidance test, animals are confined to one side of a shuttle box chamber where footshocks are delivered but the animal has the opportunity of actively escaping the footshock. Animals previously exposed to inescapable stress show reduced abilities to escape in this model. WebNonetheless, the stress-reinstatement studies have consistently shown that footshock stress increases drug-seeking behavior in dependent animals. It may well be that the mechanisms that underlie the facilitative effects of stress on stimulant self-administration and the suppressive effects of stress on alcohol self-administration are different ...

WebHere we found that acute footshock- (FS-) stress, although inducing no transcriptional and RNA editing alterations of ionotropic AMPA and NMDA glutamate receptor subunits, rapidly and transiently modulates their protein expression, phosphorylation, and localization at postsynaptic spines in prefrontal and frontal cortex. WebFootshock is a physical stressor that increases avoidance behavior on the EPM in adult rodents (Louvart et al., 2005 ), as well as causing increased immobility on EPM and open field (OF) (Anderson et al., 1976; Chalmers et al., 1974; Louvart et al., 2005 ).
