Memory consolidation was first referred to in the writings of the renowned Roman teacher of rhetoric Quintillian.He noted the "curious fact... that the interval of a single night will greatly increase the strength of the memory," and presented the possibility that "... the power of recollection .. undergoes a process of ripening and maturing during the time which intervenes."
Explicit memory (or declarative memory) is one of the two main types of long-term human memory, the other of which is implicit memory. Explicit memory is the conscious , intentional recollection of factual information, previous experiences, and concepts. [ 1 ]
REM is associated with the consolidation of nondeclarative (implicit) memories. An example of a nondeclarative memory would be a task that we can do without consciously thinking about it, such as riding a bike. Slow-wave, or non-REM (NREM) sleep, is associated with the consolidation of declarative (explicit) memories.
Declarative learning is acquiring information that one can speak about (contrast with motor learning). The capital of a state is a declarative piece of information, while knowing how to ride a bike is not. Episodic memory and semantic memory are a further division of declarative information.
The most commonly affected areas are associated with episodic and declarative memory such as the hippocampus, [35] the diencephalon, [36] and the temporal lobes. [37] The hippocampus deals largely with memory consolidation, [35] where information from the working memory and short-term memory is encoded into long-term storage for
For example, the hippocampus is believed to be involved in spatial and declarative memory, as well as consolidating short-term into long-term memory. Studies have shown that declarative memories move between the limbic system, deep within the brain, and the outer, cortical regions. These are distinct from the mechanisms of the more primitive ...
Aging has been shown to have an effect on declarative memory consolidation, which appears to be related to disruptions of sleep patterns, as well as hippocampal degeneration. However, aging does not appear to have a direct effect on motor skill consolidation, with subjects up to 95 years of age showing the ability to retain newly formed motor ...
During the acquisition process, stimuli are committed to short term memory. [1] Then, consolidation is where the hippocampus along with other cortical structures stabilize an object within long term memory, which strengthens over time, and is a process for which a number of theories have arisen to explain the underlying mechanism.
