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."
The de novo protein synthesis theory of memory formation is a hypothesis about the formation of the physical correlates of memory in the brain.It is widely accepted that the physiological correlates for memories are stored at the synapse between various neurons.
Two molecular mechanisms for synaptic plasticity involve the NMDA and AMPA glutamate receptors. Opening of NMDA channels (which relates to the level of cellular depolarization) leads to a rise in post-synaptic Ca 2+ concentration and this has been linked to long-term potentiation, LTP (as well as to protein kinase activation); strong depolarization of the post-synaptic cell completely ...
Overview of the forms and functions of memory. Memory is the faculty of the mind by which data or information is encoded, stored, and retrieved when needed.It is the retention of information over time for the purpose of influencing future action. [1]
A person's spatial memory is required to navigate in a familiar city. A rat's spatial memory is needed to learn the location of food at the end of a maze. In both humans and animals, spatial memories are summarized as a cognitive map. [5] Spatial memory has representations within working, short-term memory and long-term memory.

LONDON/SYDNEY (Reuters) -The U.S. dollar was poised for a big weekly gain on Friday, towering near one-year highs as a hawkish turn from the Federal Reserve chief sent short-term Treasury yields ...
Just one episode of CFC can result in a life-long fearful memory. [79] After an episode of CFC, cytosine methylation is altered in the promoter regions of about 9.17% of all genes in the hippocampus neuron DNA of a rat. [80] The hippocampus is where new memories are initially stored. After CFC about 500 genes have increased transcription (often ...
