WebPrevious studies suggest that stress associated to sleep deprivation methods can affect the expression of sleep rebound. In order to examine this association and possible mechanisms, rats were exposed to footshock stress during or immediately after a 96-h period of paradoxical sleep deprivation (PSD) and their sleep and heart rate were recorded. WebFeb 4, 2016 · The footshock- (FS-) stress protocol was performed essentially as previously reported (40 min FS-stress: 0.8 mA, 20 min total of actual shock with random intershock length between 2 and 8 sec) [ 8, 12, 13 ]. Sham-stressed rats (controls) were kept in the stress apparatus without delivering of shocks.
WebObjectives: The objective of this study was to test the hypothesis that cannabinoid type 1 receptor (CB1R) signaling is required for stress-potentiated reinstatement of cocaine seeking in rats. Methods: Following i.v. cocaine self-administration (2 h access/day) and extinction in male rats, footshock stress alone does not reinstate cocaine ... WebFor three groups, the contingencies of footshock treatments were manipulated to reinforce alternation, perseveration, or both. A control group that was not administered footshock alternated, but all three groups that were stressed perseverated more and more across tests, despite the differences in reinforcement contingencies.
WebJun 29, 2015 · In summary, exposure to footshock stress initiates pronounced signaling changes in mPFC and freezing behavior and β-noradrenergic blockade by propranolol mitigates these effects. Collectively, these findings shed light on prefrontal executive control of fear-related behavior while also suggesting that propranolol treatment may enhance ... WebSep 9, 2024 · Then, we examined the effect of stress on the functional changes of those specific neuronal populations using a mouse model of inescapable footshock stress. The results showed that the fibers of the contralateral projecting BLA neurons labeled by enhanced green fluorescent protein (EGFP) have no collateral projections to the …
