1. Análise neurofarmacológica e neuroquímica da expressão de memórias espaciais
Memories are not stored in its final form immediately after the acquisition. They undergo a long stabilization process known as consolidation. Consolidated memories can become labile again after the retrieval and susceptible to the action of amnesic agents. Thus, to persist must go through the re-stabilization process called reconsolidation. Several evidence

2. The influence of stress on fear memory processes
It is well recognized that stressful experiences promote robust emotional memories, which are well remembered. The amygdaloid complex, principally the basolateral complex (BLA), plays a pivotal role in fear memory and in the modulation of stress-induced emotional responses. A large number of reports have revealed that GABAergic interneurons provide a powerfu

3. Treatment of fear memories: interactions between extinction and reconsolidation
A evocação labiliza os arquivos de memória, e isto permite dois processos dependentes de síntese protéica no cérebro: a extinção, que inibe a evocação ulterior, e a reconsolidação, que pode aumentar a evocação ou mudar seu conteúdo. A extinção pode por sua vez sofrer reconsolidação. Interações entre estes dois processos podem ser aplicad

4. Papel de mTOR na formação e reconsolidação da memória
Novas informações assimiladas pelo sistema nervoso primeiramente ficam em um estado de labilidade para depois se estabilizarem através de um processo conhecido como consolidação, que envolve síntese de proteínas. Depois da reativação, uma memória previamente consolidada retorna ao seu estado de labilidade, e para que volte a ser estável, é necess

5. Pharmacological effects and behavioral interventions on memory consolidation and reconsolidation
In this article, we will review some behavioral, pharmacological and neurochemical studies from our laboratory on mice, which might contribute to our understanding of the complex processes of memory consolidation and reconsolidation. We discuss the post-training (memory consolidation) and post-reactivation (memory reconsolidation) effects of icv infusions of

6. Activation of the transcription factor NF-κB by retrieval is required for long-term memory reconsolidation
Several studies support that stored memories undergo a new period of consolidation after retrieval. It is not known whether this process, termed reconsolidation, requires the same transcriptional mechanisms involved in consolidation. Increasing evidence supports the participation of the transcription factor NF-κB in memory. This was initially demonstrated i

7. Retrieval Does Not Induce Reconsolidation of Inhibitory Avoidance Memory
It has been suggested that retrieval during a nonreinforced test induces reconsolidation instead of extinction of the mnemonic trace. Reconsolidation would preserve the original memory from the labilization induced by its nonreinforced recall through a hitherto uncharacterized mechanism requiring protein synthesis. Given the importance that such a process wo

8. Direct comparisons of the size and persistence of anisomycin-induced consolidation and reconsolidation deficits
An issue of increasing theoretical interest in the study of learning is to compare the processes that follow an initial learning experience (such as learning an association between a context and a shock; memory consolidation processes) with those that follow retrieval of that learning experience (such as exposure to the context in the absence of shock; memor

9. Mismatch Between What Is Expected and What Actually Occurs Triggers Memory Reconsolidation or Extinction
In previous experiments on contextual memory, we proposed that the unreinforced re-exposure to the learning context (conditioned stimulus, CS) acts as a switch guiding the memory course toward reconsolidation or extinction, depending on reminder duration. This proposal implies that the system computes the total exposure time to the context, from CS onset to

10. Mapping of Olfactory Memory Circuits: Region-Specific c-fos Activation After Odor-Reward Associative Learning or After Its Retrieval
Although there is growing knowledge about intracellular mechanisms underlying neuronal plasticity and memory consolidation and reconsolidation after retrieval, information concerning the interaction among brain areas during formation and retrieval of memory is relatively sparse and fragmented. Addressing this question requires simultaneous monitoring of acti

11. Long-term memory for instrumental responses does not undergo protein synthesis-dependent reconsolidation upon retrieval
Recent evidence indicates that certain forms of memory, upon recall, may return to a labile state requiring the synthesis of new proteins in order to preserve or reconsolidate the original memory trace. While the initial consolidation of “instrumental memories” has been shown to require de novo protein synthesis in the nucleus accumbens, it is not known

12. Memory reconsolidation for natural language processing
We propose a model of memory reconsolidation that can output new sentences with additional meaning after refining information from input sentences and integrating them with related prior experience. Our model uses available technology to first disambiguate the meanings of words and extracts information from the sentences into a structure that is an extension
