I prepared the attached consideration of your question.

Although this document shows that sharper memory can be produced by a biological variance or mutation governing the density of white matter, the issue of memory creation is that 2/10ths of a second produces a very clear and permanent engram without further repetitions.

re-encountering the triggers to memory merely adds access to the existing memory since, while the new access is experienced the trigger restores the engram neurons to active, and they bind in with the new active neurons - expanding the existing engram, and especially expanding access to it.

Trying to change the memory is impossible, however it is possible to create new memory and integrate it but alternative contexts are needed.

Visual + auditory + tactile + proprioceptive cues have to be configured to help the new memory establish an alternative engram dimension, to counteract the sharp Mega memory instance that is erroneous.

The type of memory you are describing is often referred to as highly superior autobiographical memory (HSAM) or hyperthymesia. Individuals with HSAM have the ability to recall detailed and specific information about events from their own life, as well as information from other domains, with exceptional accuracy and vividness. They often report that these memories come to mind involuntarily, without any conscious effort to retrieve them.

The inability to update or revise memories in individuals with HSAM may be related to the way their memories are stored and retrieved. Research suggests that individuals with HSAM have highly efficient and reliable retrieval processes, which allow them to access memories quickly and accurately. However, this efficiency may come at the cost of flexibility and updating, as memories may become so strongly encoded that they are resistant to change.

The causes and mechanisms underlying HSAM are not yet fully understood. Some research has suggested that HSAM may be related to differences in brain structure or function, such as increased connectivity between certain brain regions involved in memory processing. However, more research is needed to fully understand the underlying neural mechanisms of HSAM.

It's important to note that HSAM is a rare phenomenon, and not everyone with exceptional memory abilities has HSAM. While memory abilities can be enhanced through various techniques and strategies, the type of memory observed in individuals with HSAM appears to be a unique and innate ability.

I know a bit more about this from autopsy as well. I was also diagnosed with autism spectrum disorder as a child.

yes, what the original questioner here referred to as Mega memory is HSAM, is that not right Vahid Rakhshan

I am involved in what is memory how is it formed and retrieved, and I have discovered that both memory formation and retrieval are one thing and I describe that thing in my work and allude to it and use it in my JavaScript demo mentioned on the page.

I would say that if you have it your memories are clearer than is the case for people who do not have it.

The strategies to manage access to memory are best developed by understanding that memory is a reflex of the mind to the context, and what you have recently been doing (aka short term memory)

No I was not meaning HSAM, because that entails remembering EVERYTHING they encounter in an unctrollable and inundating manner. Besides, I am not sure if HSAM is non-updatable. (I just don't know).

What I have seen is perhaps a much milder and very tolerable form of HSAM. These people are not overwhelmed by floods of unnecessary memories the way people with HSAM are. They have almost full control over the memories they want to remember (like us mortals). But at the same time, they can memorize and remember almost whatever they WANT.

But interestingly, they can't easily update or correct their learnings once formed.

HSAM is seen in about 47 people worldwide. What I am talking about is much more prevalent. Perhaps I can call it some form of genius, or as I said, mega memory.

Larry Carlson from https://www.researchgate.net/post/What-could-be-proof-of-consciousness :

Jerry: In all cases the accessiblity of the memory is based upon the contextual cues. *...

The strategies to manage access to memory are best developed by understanding that memory is a reflex of the mind to the context, and what you have recently been doing (aka short term memory)" **

Larry: In general, I gather that you are emphasizing the notion that memories become 'stronger' as a result of more extensive reticulation and articulation, as opposed to simply or entirely being the result of changes in the strength of connections between neurons.

Perhaps this claim is in keeping with "Ramon y Cajal’s suggestion that synaptic connections between neurons are not immutable but can be modified by learning, and that those anatomical modifications serve as elementary components of memory storage...Changes in synaptic strength [can occur] not only in the connections between sensory neurons and their motor cells but also in the connections between the sensory neurons and the interneurons." ***

In short, one is more likely to recall that which has the most intricate relationships with analogous events, and not those which are most homogenous, brute, and simple. But is this not another way of saying that those objects, situations, and events with the most connotations are most meaningful and memorable to us, since our memory is stimulated by new and thus somewhat surprising contexts in which an object/event is presented to us.

Friston's model, I gather, relates the manner in which the brain is updated so as to modify its perceptions and and memories to thermodynamics. As per Friston, "facing a novel or dangerous situation" causes the system of neural pathways to update their perception. Correspondingly, in terms of thermodynamics, "free energy is also large due to the initial blood and energetic inflow that accompanies a novel situation, [though] this amount will be rapidly reduced by the activation of neuronal paths that consume free energy in the least possible time. By doing so, the brain is carrying out a codification task in the sense that a smaller amount of free energy will be necessary to activate the same neuronal path on subsequent occasions," thereby enabling one to better predict the behavior of said situation in the future. In this way, the longevity of an organism's life is increased, thereby enabling it to consume a greater amount of free (accessible) energy than it normally would have, had it not as accurately recalled and predicted a life enhancing or life threatening situation (e.g., an approaching lion).

As per the 2nd law of thermodynamics, "Every energy transfer or transformation increases the entropy of the universe since all energy transfers result in the loss of some usable energy." Living things evidently tend to temporarily reduce the rate of entropy increase so as to eventually reap a greater net increase in entropy over their lifetime. I get the impression that more intelligent organisms (such as humans) are consuming a more refined sort of energy (in the process, perhaps, of producing a more refined sorts of information) than, say, a bat.

In this way, the more intricate neural system of humans enable them perceive and recall objects and situations in a more subtle and refined manner than do most other living things and recall. By virtue of their more intricate neural systems, humans are able to make and recall a wider and more extensive of range of conceptual relationships and contextual associations among the various situations they encounter and prosperously navigate. If so, arguably, the more advanced and complex organisms (those with 'higher' levels of associative capabilities, recall ability, intelligence, and thus situational awareness) would be better able to process types of energy and information which would not otherwise be processed by lower organisms or by more basic inorganic things. This approach is in keeping with the negentropic concept that life forms came into existence in order to address what might be the less accessible forms of free energy so as to ultimately increase the overall amount of entropy.

I am not inclined to follow the entropy logic with regard to memory.

I do not feel it is the right tool for that job.

I answered Larry Carlson and you can read that response there, but again I completely refute that one engram is stronger than any other memory engram.

Access to the engram - i gave examples- however can be more or less prevalent.

In particular there are more reasons to hit the brakes, so it is more frequently accessed than turning left, but there are more engrams for turning left than hitting the brakes.

In America wee drive on the right, the left turn is more complex.

Jerry Waese I just copied Larry's comment here because I want this thread to be as informative as possible for future readers. I will copy your responses to Larry here too, with your permission.

Regarding your comment, well you have an interesting hypothesis. Some researchers should step forward to experimentally test it. I would love to do it if I could devise a proper experimental design for it.

By the way, I haven't been able yet to read your very first comment here and your other comment on that other thread about your GitHub project. I will respond soon. Thanks again.

Jerry Waese to Larry Carlson:

Larry Carlson memory content can be stronger in so many ways but the memory engram is never any stronger than any other memory engram except in terms of accessibility of it.

i.e. how many different things lead to the reflex activation of the engram.

Greater access is afforded by the extent of interconnection with other engram patterns, while greater clarity is afforded by the extent of difference or uniqueness to other engrams.

I may have 500 "master engrams" that are instrumental in my most salient reflexes as I sit before the laptop screen in my bath. AND I may have 500 similarly instrumental salient reflex perturbing engrams that govern driving while seated in my car.

In the first case, what I am typing may have or may not have any effect on where I go, or what others think. In the second case my own life and others lives depend on what those reflexes do while driving.

The many conditions that lead to me hitting the brakes make that set of braking engrams (maybe 20/500 "master braking engrams" (i.e. administrative controlling engrams that cascade into multiple body articulation and movement engrams)) more accessible than the left turn engrams (maybe 100/500 deal with left turn considerations)

Fortunately I spend more time typing (not always in the bath) than driving.

The relation to intelligence and thermodynamics is a different story, but if we make it the same story it probably will not matter if I get clean (in the bath), communicate well (at RG) or drive into a wall.
