How is Memory Stored Within the Brain?

Recommendable! More about insights into lifetime, long-time and short-time memory! How similar are long-term memory and instincts? To what extent can forgotten memory be retrieved again?

"... Then we stimulated engram cells and discovered we could retrieve lost memories from memory loss. ...
It showed ... that the two contradictory aspects of memory can be reconciled. “We could explain why memory is both fragile and lasts forever, because not all memory loss is about losing the memory,” ...
lab began to reverse that access and realized accessibility to a memory may be differentially modulated by experience—which is quite different than the memory itself. ...
“Novel methodologies led to experiments that open doors to new ways of thinking about memory and forgetting as an adaptive process,” ...
“If it lasts your entire lifetime, it must be stored by a durable mechanism.”
... probably stored by changing the wiring of the brain itself, changing connectivity patterns, which enable long-term information storage. “This means we may be storing memory within microanatomical patterns rather than just the strength of synapses,” ... “If true, we can consider memory to be the same as instinct.”
Instincts are genetically wired and stored within the brain as hardwired anatomical pathways. If memory and instinct are stored in the same way, memory can influence the evolution of instinct. ...
In a sense, the brain may not know the difference between a memory and an instinct. “They may be essentially the same thing, just derived from different origins,” ... “This is a hypothesis my lab is currently doing experimental work on.” ...
exploring forgetting. “Forgetting, in general, may be functional and it may be a product of environmental experience,” he says. “It could be a purposely reversible process—the brain is a constantly developing machine that acquires and changes its beliefs about the world. And a lot of that involves differential learning and forgetting information and relearning.” ..."

How is Memory Stored Within the Brain? | Kavli Foundation Tomás Ryan explores the commonality of memory and instinct to try to understand how the brain stores informational units. Neuroscientists don’t fully understand how information gets encoded within our brains, but Tomás Ryan, a neuroscientist and associate professor in the School of Biochemistry and Immunology at the Trinity College Institute of Neuroscience in Dublin, Ireland, as well as the chair of the Federation of European Neuroscience Societies (FENS)-Kavli Network, is shining new light on memories and their storage mechanism.
