All animals were trained and tested in a contextual fear conditioning task.
The effects of CBD on contextual fear indicate a possible therapeutic action of this cannabinoid in post-traumatic stress disorder.
Study of the cortical circuitry underlying contextual fear processing to predatory….
The aim of this study was to evaluate the effects of corticosterone in the consolidation of recent andremote memory of wistar rats subjected to contextual fear conditioning.
Unravelling the temporal role of hippocampal subareas on contextual fear memory retrieval and discrimination, BE.EP. IC Abstract.
In rats, an excellent paradigm for the behavioral study of recent andremote memories is contextual fear conditioning.
Here we found that reconsolidation of a contextual fear conditioning(cfc) memory allowed ltm formation of a weak spatial object recognition(wsor) training applied closely in time.
This model was generated after the selection of wistar rats with higher freezing in contextual fear conditioning.
Rats were submitted to contextual fear conditioning and had the pl stimulated through nmda receptors activation(30-300pmol/side) immediately after.
Completed(most recent) Alterations of sleep and corticosterone secretion during the extinction of contextual fear conditioning, BP. IC.
It is well established that contextual fear memory relies on the hippocampus for expression shortly after learning, but it becomes hippocampusindependent at a later time point.
It has recently been demonstrated that systemic administration of spd improves the persistence andreconsolidation of memory in contextual fear conditioning task in rats.
In this study, using pavlovian contextual fear conditioning in rats, we explored the role of the cannabinoid system in the rsc on memory consolidation, reconsolidation, and extinction.
Carioca high-freezing rats(chf)are animals selected by their high freezing response in contextual fear conditioning and represent a useful model of anxiety disorder.
This study investigated the effects of protein synthesis inhibition andblockade of nmda receptors in the hippocampus of pigeons on reconsolidation and extinction of contextual fear memory.
The pre-limbic region of the prefrontal cortex appears to underlie this effect of CBD,as the reduction in contextual fear produced by systemic administration of CBD 10 mg/kg is associated with reduced c-Fos expression in this area.
However, this receptor system seems to be involved in anotheranxiolytic-like action of CBD, according to tests using a procedure known as contextual fear conditioning.
The animals were familiarized in context for 3 minutes,after 24 hours conditioning session the contextual fear(0.6 ma, 3 s, 30 s interval between shocks), memory retrieval(3 min) test a1 and a2 test 3 min in the context a, 24 hours and 7 days after the retrieval.
Thus, the present study investigated the involvement of bnst noradrenergic system in modulating of behavioral andautonomic responses induced by contextual fear conditioning(cfc) in rats.
The contextual fear conditioning task(cfc) was employed to assess the effect of treatments on different stages of long-term memory: acquisition(infusion 30 min before training session), consolidation infusion immediately after training s.
Previously, it was shown that intra-dh injections of 8-oh-dpat, a 5-ht1a receptor agonist,inhibited the expression of contextual fear when administered 6 hours after conditioning.
Adult male rats were submitted to contextual fear conditioning task and the memory of this task was measured as percentage of observations of immobility("freezing") 2, 7 or 14 days after training. morphine administration(10 mg/kg, i.p.), 12 hours post-training.
For this, adult male wistar rats with cannulas implanted bilaterally in the ca1 region of the hippocampus or the bla,were trained in contextual fear conditioning or social recognition tasks.
In this sense, the aim of the present study was to verify the parameters in which contextual fear conditioning occurs by contextual representation maintenance over a discontinuity time interval idt.
This study evaluated the systemic administration of the effect of tmx(1, 10 or 50 mg/ kg) immediately, 6, 9 and12 hours after the reactivation of memory in rats submitted to the contextual fear conditioning.
Thus, we investigated the effect of the antagonism of cb1 receptors with am 251(0.1-1.0 mg/kg)on the consolidation of a contextual fear memory in male wistar rats tested during the diurnal(7-8h) or nocturnal(19-20h) period.
Therefore, the aim of this study was to evaluate the effect of intra-hippocampal infusion of spd in the persistence of memory andthe persistence of memory reconsolidation of animals subjected to contextual fear conditioning ta.
Thus, the objective of the present study was to investigate whether the increased activity of pl cortex during the contextual fear memory processing would be able to induce fear generalization.
Previous results from our lab show that paradoxical sleep deprivation produces a wide range of physiological and behavioral alterations, such as pronounced weight loss during the 4 days of deprivation, andperformance deficits in some memory tasks, like contextual fear conditioning.
Thus, the purpose of the present study was to investigate the role of serotonergic and gabaergic mechanisms of dh andmpfc in the expression of contextual fear 24 h after conditioning, reflected by fearpotentiated startle(fps) and freezing behavior.
