memory consolidation

memory consolidation

A process whereby a memory becomes increasingly resistant—due to physical and psychological changes—to interference from competing or disrupting factors with the passage of time, as the brain organises and restructures information that become a permanent part of memory.

Memory consolidation is associated with sudden bursts of oscillatory brain activity, called sleep spindles, which can be visualized and measured on an electroencephalogram (EEG).
So, in my opinion, this study brings back REM sleep as a sleep stage that is important for brain function, and that neural activity occurring specifically during REM might be critical for normal memory consolidation and protective against Alzheimer's," Osorio said.
Sleep disruption may explain the association of these substances with less memory consolidation, poorer academic performance, and higher rates of risk behaviors.
But skewed CB-1 signaling, due to endocannabinoid deficits (low serum levels of anandamide), results in impaired fear extinction, aversive memory consolidation, and chronic anxiety, the hallmarks of PTSD.
However, what really interested me and brought me to reconsider my sleeping habits was that sleep helps in memory consolidation, which means, it allows the brain to engrave important memories and keep them for longer.
Lack of sleep is thought to reduce the process of memory consolidation in which information is moved from short-term memory into long-term memory repositories in the brains hippocampus.
Current memory consolidation models postulate that memory storage in our brains occurs by a dynamic process- a recent episodic experience is initially encoded in the hippocampus, and during off-line states such as sleep, the encoded memory is gradually transferred to neocortex for long-term storage.
The researchers trained the rats to complete a task over four days, followed by several days of memory consolidation by performing the task over and over again.
Several studies have confirmed the hypothesis that sleep contributes to processes of memory consolidation and brain plasticity.
Sleep Seven to eight hours per night is massively important for both recovery and memory consolidation.
Further studies show that if we don't sleep in sync with our circadian rhythm, our REM phase of sleep and other important sleep processes become inefficient, which has been shown to lead to inefficient memory consolidation.
