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.
Consolidation of a memory is a process that takes an initially unstable representation and encodes it in a more sturdy, effective and efficient manner. In this new state, the memory is less susceptible to interference. [1] There are essentially three phases of memory consolidation and all are thought to be facilitated by sleep or not sleep:
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.
The involvemnt of arginine and nitric oxide in memory consolidation has been confirmed in birds, mammals and other creatures, including humans. [48] Glial cells have also an important role in memory formation, although how they do their work remains to be unveiled. [49] [50] Other mechanisms for memory consolidation can not be discarded.
One extensively studied anterograde amnesiac patient, codenamed H.M., demonstrated that despite his amnesia preventing him from learning new declarative information, procedural memory consolidation was still possible, albeit severely reduced in power. He, along with other patients with anterograde amnesia, were given the same maze to complete ...
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. [1]
