Synapses 1 4 were thereby repeatedly made available for storage of new memories, and were then repeatedly strengthened by L-LTP – inducing events.
Here, we review anatomical, behavioral, and physiological data which suggest that the connections in and between the entorhinal and cingulate cortices may be uniquely important for the long-term storage of memories that initially depend on the hippocampus.
These data support the notion that synaptic growth and remodeling are dynamic processes that may provide an anatomical substrate for the formation and storage of memories in the adult brain.
For several decades, synaptic plasticity has been considered the best candidate mechanism for the formation and storage of memories.
The preservation of this pattern is necessary for the overall generation and storage of memories, as well as the acquisition of other higher brain skills.
Sleep is known to provide optimal neurobiological conditions for consolidation of memories for long-term storage, whereas sleep deprivation acutely impairs retrieval of stored memories.
Mutant and transgenic studies suggest a possible distinction between them as neural substrates for representations of memories consolidated at different stages of development [18], discrete phases of memory, [28], [31], [50] [52; see discussion in ref. 38], or conduits to extrinsic sites downstream of the MBs for memory storage and retrieval [47], [48].
The caudomedial nidopallium (NCM) is an important site for the storage of auditory memories, particularly song, in passerines.
Until now, there was no information regarding how these cells were involved in performing this computational process and which plasticity signals were required for successful storage of distinct memories of similar spatial representations.
One says that it stores a cognitive map, the other that it is a key locus for the temporary storage of episodic memories.
