“…Water deprivation as internal cue strengthens the expression of a weak memory but is not sufficient to induce memory retrieval in a novel context by itself Previous studies have postulated that interoceptive cues experienced under a given drug or hormonal state might act as a contextual cue for retrieval (Spear 1978;Riccio and Concannon 1981). This concept was consistently confirmed in classical experiments of state-dependent memory (Bormann and Overton 1993).…”

Reconsolidation may incorporate state-dependency into previously consolidated memories

Some memories enter into a labile state after retrieval, requiring reconsolidation in order to persist. One functional role of memory reconsolidation is the updating of existing memories. There are reports suggesting that reconsolidation can be modulated by a particular endogenous process taking place concomitantly to its natural course, such as water or sleep deprivation. Here, we investigated whether an endogenous process activated during a natural/physiological experience, or a pharmacological intervention, can also contribute to memory content updating. Using the contextual fear conditioning paradigm in rats, we found that the endogenous content of an aversive memory can be updated during its reconsolidation incorporating consequences of natural events such as water deprivation, transforming a previously stored memory into a state-dependent one. This updating seems to be mediated by the activation of angiotensin AT1 receptors in the dorsal hippocampus and local infusion of human angiotensin II (ANGII) was shown to mimic the water deprivation effects on memory reconsolidation. Systemic morphine injection was also able to turn a previously acquired experience into a state-dependent memory, reproducing the very same effects obtained by water deprivation or local angiotensin II infusion, and suggesting that other state-dependent-inducing protocols would also be able to contribute to memory updating. These findings trigger new insights about the influence of ordinary daily life events upon memory in its continuing reconstruction, adding the realm of reconsolidation to the classical view of endogenous modulation of consolidation.

Two experiments with rats investigated the effectiveness of prior-cuing treatments for alleviating forgetting of aversive conditioning. The aim was to see which retrieval cues would be most effective within different contexts. Experiment 1 examined the contexts of classical fear conditioning and instrumental avoidance training. The results indicated that the response components were sufficient to reinstate avoidance training, whereas the unconditioned stimulus (US) was most effective for classical fear conditioning. In Experiment 1, the reinforcer per se was ineffective in reinstating instrumental avoidance training. Experiment 2 manipulated the training context and found that the US could be made an effective prior-cuing treatment for instrumental training if classical conditioning components were more prevalent during training. These results are interpreted to mean that a "critical context" must be reinstated by the cuing treatment if this treatment is to promote retrieval of the memory.
