Dreams and Memory Consolidation

Sleep is a very interesting phenomenon that the mind is almost completely separated from the normal conscious area. It is different from quiet awakening, ability to respond to stimuli, and lack of understanding of the surrounding environment. However, it is easier to reverse than sleeping or coma. This is a function that has been widely studied by many people. After all, we have not evolved a mechanism to force us to spend a third of our life unless sleep is good for us.

The problem of "relaxing sleep-based memory integration" is a complex problem. Clarification is necessary for all terms of the phrase "sleep", "dependence", "memory", "integration". First, the term "memory" encompasses a wide variety of different types of memory which differ in the type of information stored, the regulation of such stored brain structure, and the ability to consciously acquire information in humans . Currently, there is no clear consensus on both the content of information and the brain structure related to storage concerning the number of such storage systems and how to define them. The most widely accepted taxonomy is to first classify human memory declaratively and non declaratively based on accessibility to conscious recall and then divide it into finer subdivision of these basic categories (Fig. 1A).

Memory integration is a kind of process that stabilizes memory tracking after initial acquisition. Integration is divided into two concrete processes: synaptic integration (synonymous with long-term long-term potentiation) occurring in the first few hours after learning and system integration in which memory dependent on hippocampus is independent from the hippocampus for a certain period of time I will. Several weeks to several years. Recently, the third process is the focus of research and reintegration. Also, if you enable memory tracking again, previously integrated memory may become unstable again.
