Researchers discover dynamic DNA structures that regulate the formation of memory
An international collaborative research team, including scientists from UQ's Queensland Brain Institute (QBI), has discovered a novel mechanism underlying memory involving rapid changes in a specific DNA structure.
Those of you who know neural networks, may believe that memory lives in the synapse. (Because of all the recent successes with AI, including the Chat GP4-style self-attention transformers).
But this does not explain how cells in the hippocampus (and nearby EC) turn over every 30 days, yet somehow we retain our memories.
And, it also doesn't explain the need for, or transition between, short term and long term memory.
Well, here's a clue.
It is very likely that ASTROCYTES are responsible for transmitting these experience based changes from one cell to the next.
