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 ]
Declarative memory has also been shown to benefit from sleep, but not in the same way as procedural memory. Declarative memories benefit from the slow-waves nREM sleep. [ 7 ] A study [ 12 ] was conducted where the subjects learned word pairs, and the results showed that sleep not only prevents the decay of memory, but also actively fixates ...
The study adds to evidence showing sleep’s crucial role in memory consolidation, and may help scientists come up with preventive strategies against dementia. ... Geiger and Henrik Alle — a co ...
Another key piece of evidence regarding SWS’s involvement in declarative memory consolidation is a finding that people with pathological conditions of sleep, such as insomnia, exhibit both reduction in Slow-Wave Sleep and also have impaired consolidation of declarative memory during sleep [35]. Yet, another study found that middle aged people ...
Young woman asleep over study materials. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, [1] is a product of brain plasticity, the structural changes within synapses that create associations between stimuli.
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.
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.
