Aug 15, 2018 · Memory: the contemporary scene. Three approaches have dominated memory research over the last quarter century. The first relates to the search for plastic mechanisms at the synapse, where a key focus has been on glutamate receptors and the downstream biochemical pathways that regulate their expression at the synapse.

Apr 15, 2024 · In this context, this work presents a descriptive comparative analysis of contemporary models that address the structure and function of multiple memory systems. The main goal is to outline a panoramic view of the key elements that constitute these models in order to visualize both the current state of research and possible future directions ...
I present an account of the origins and development of the multicomponent approach to working memory, making a distinction between the overall theoretical framework, which has remained relatively stable, and the attempts to build more specific models within this framework. I follow this with a brief discussion of alternative models and their relationship to the framework. I conclude with ...
In the evolutionary model, memory continues to be seen as modular, but its architecture is very different compared with the medial temporal lobe model (Fig. 1A): the amygdala-, striatum-, and cerebellum-based memory systems are grouped together under the reinforcement memory system; several new systems are newly defined; and priming and the medial temporal lobe are not acknowledged. Episodic ...

Sep 9, 2021 · In fact, it has been shown that co-retrieval of independent memories can lead to memory linking via overlapping ensembles (Yokose et al., 2017) and that post learning optogenetic-reactivation of the memory ensembles of two different memories in the HPC is sufficient to induce memory linking (Oishi et al., 2019). Thus, increases in neural excitability could be an effective way to ensure the ...

Stages of memory: Sensory, short-term, and long-term memory. One way of understanding memory is to think about it in terms of stages. The Atkinson-Shiffrin model of memory, also called the three-box model, (Atkinson & Shiffrin, 1968) describes three stages, or boxes, in the active process of creating a memory.

An alternative view, the embedded processes model put forward by Cowan (1999), is that working memory can be seen as the controlled, temporary activation of long-term memory representations, with access to awareness being limited to three to four items or chunks. A key distinction with the multicomponent model hangs on whether working memory relies on a distinct substrate (as implied by the ...
