No difference in structure perhaps but definitely a difference in how readily that stored information / data is accessible when needed. This is especially evident in some people that tend to misplace things or fail to recall a name, date or place that they know they know.
Perhaps a better way for me to describe it is weak to strong memories on a linear scale; using the same architecture/ schema. So short is a weak memory and strong is a long term memory. We don’t have mid term or super long term memories… where would you draw the line? I think the whole long/ short thing is very misleading.
When we form a memory we are just linking together existing knowledge/ understanding/ experiences with weak synaptic connections/ associations.
Short term memory is what you had for breakfast 20 minutes ago yet there are people who couldn't provide an accurate description.
To remember what I had for breakfast I have to use strong/ long term memories. To understand what the items were, what they were called, even the concept of ‘breakfast’ requires a lot of strong/ long term understanding/ knowledge/ memories. The weak/ short term bit of the memory is what links all the various items together along with a location/ timestamp/ index/ etc that I would recall as ‘earlier today’. For the unfortunate people who have difficulty retrieving today’s (short term) memories I would wager they have a problem with a brain region responsible for temporal tagging/ indexing the memory as ‘today/ recent’
Doctors address these as Short Term Memory and Long Term Memory as different area of the brain.
I’m not sure about this; I have no reference to any research that specifically points to long/ short term memories being stored in different brain locations. I could how ever explain why a scientist/ neuroscientist might think this was the case. Different brain regions supply different facets of a memory. The Hippocampus (could be revised) for example provides an index/ temporal date stamp to a memory as its being stored (not read); if they where viewing frmi results on memory consolidation they would be measuring the difference between existing knowledge and new learning. The new learning would require a recent time/ stamp that would activate the Hippocampus (episodic), blood would flow to this region highlighting it.
That same person might be able to tell you what they had for dinner on their 21st birthday (Long Term Mem).
Once a memory has been consolidated it can be recalled by any small aspect/ facet of the original/ whole memory. A smell or even an image (pareidolia) can trigger a memory/ recognition event.
If any of the original facets that the memory was comprised of are compromised in some way it can make retrieval difficult from that aspect, time, location, etc… we all use the tactic of thinking of related/ similar memories when trying to recall a weak memory, you’re just trying to produce a global pattern conducive to triggering the required memory; trying to fill in the missing blanks in the pattern that will trigger retrieval.
The limbic (emotional) network adds a very strong facet to a memories overall pattern; this is how repressed emotional memories are triggered. The memory was painful so we made the effort to forget/ shun it from our normal thoughts… the links that would trigger the memory from day to day thoughts become weaker and so it doesn’t pop into our heads. A strong emotional response however from an unrelated experience can be enough to trigger a total recall.
This is a diagram showing a rough map of where the various categories within the circle where detected upon the human cortex surface.
This is a short video showing the same/ similar category organisation within my AGI’s cortex. As usual the forty test patterns (phonemes, images, etc) are shown on the right; the confidence in recognition (height of the bar) is shown on the bottom left. Notice the regular modulated input pattern below the pattern input on the right. The cortex section has very high confidence in its recognition of the patterns until I click ‘A’ in the lower right to turn this regular injected pattern off. Then the cortex sections confidence drops/ stops… I have removed a facet of the overall pattern that the system was using to recognise the patterns. This is a kin to disconnecting the hippocampus or limbic system… it makes a big difference.
I have to take exception to that
And so you should, that’s the point of the forum, to discuss theories and ideas. I’m constantly revising/ improving my code/ theories and welcome any and all input/ ideas/ theories.
Glad you like it and congrat’s on passing 700 lol.
