Memory consolidation is a category of processes that stabilize a memory trace after its initial acquisition. [1] A memory trace is a change in the nervous system caused by memorizing something. Consolidation is distinguished into two specific processes.
In psychology, multiple trace theory is a memory consolidation model advanced as an alternative model to strength theory.It posits that each time some information is presented to a person, it is neurally encoded in a unique memory trace composed of a combination of its attributes. [1]
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.
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.

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 ]
Participants read ten words and are asked to recall as many of the words as they can in no particular order. Then participants were asked to keep a diary on their memory process between two one-hour experimental sessions. They were asked to record autobiographical memories as soon as possible, using a two-page questionnaire for each memory.
It has been argued that memory consolidation occurs more than once- each time a memory is recalled, it returns to a labile state. It states that things which cause memory loss after initial learning can also lead to memory loss after reactivation or retrieval [ 10 ] and it is by applying a pharmacological intervention at this plastic point ...
Hippocampal replay is a phenomenon observed in rats, mice, [1] cats, rabbits, [2] songbirds [3] and monkeys. [4] During sleep or awake rest, replay refers to the re-occurrence of a sequence of cell activations that also occurred during activity, but the replay has a much faster time scale.
