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."
Systems consolidation is the process by which memories are shifted from a vulnerable state to a fairly permanent one. [11] It also describes roles that certain brain structures, most notably the hippocampus, play in memory consolidation and the extent certain types of memories can be consolidated.
Short-term memory (STM) is temporary and subject to disruption, while long-term memory (LTM), once consolidated, is persistent and stable. Consolidation of STM into LTM at the molecular level presumably involves two processes: synaptic consolidation and system consolidation.
This slow process, referred to as consolidation, allows emotions to influence the way the memory is stored. [7] The amygdala is involved in memory consolidation, which is the process of transferring information that is currently in working memory into ones long-term memory. This process is also known as memory modulation. [7]
The hippocampus plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation. In humans, and other primates the hippocampus is located in the archicortex , one of the three regions of allocortex , in each hemisphere with neural projections to the neocortex .
The standard model of systems consolidation largely applies to the formation of declarative memories, which include semantic, factual memories and episodic, autobiographical memories. This has been supported by case studies of human patients with MTH lesions who exhibit difficulties in remembering experiences and fact learned post-surgery ...
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:
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.
