- (Visit: www.uctv.tv/) How do we create and store memories? Larry Squire PhD joins William Mobley MD, PhD to dissect these processes and how we might use this knowledge to aid in the fight against Alzheimer's disease. Series: "The Brain Channel" [Health and Medicine] [Show ID: 27743]
iI wish I could understand the movie 'Memento' in this regard i watched the movie several times,however I did not understand if the person really did an action and had problem remembering, or he made things up for himself, the same was the movie the Island by Dicaprio
13:40, regarding color ability, that's amazing to know but kind hard to understand.
What if some of us can recall an interaction with another person in our mind after it happened and add to that event by adding more to that conversation in a different state of thinking that they were in initially. Like if you got mad at a person and were unhearing of them and you could look back at it later after you had changed states or learned new ways of thinking.
What if.
99.9999999999999999999999% of the population will never believe it exists even if it happens to them and someone does it. Because it is new and unheard of.
this is just a laymans atempt to describe memory by concept in form of philosophy. how the brain actually works at the atomic molecular level is the real secret. the brain contain braincells that arange atoms together into a tiny pattern. when many neurons work together they stitch together all these pieces of pattern into a bigger pattern. the brain works by stiching together pieces of molecule assembly by intercellular comunication that create the image of the memory itself. the brain organize neurons like a fractal. its a hirachy of clusters of celular rewiring to create your memories. each cell have a repository of other pieces that can store memory in dna inside neuro spheres that contains bundles of dna specially designed for storing memory.
It introduces the primary patient case study of the specific topic of skilled memory in neurology. It helps show what has been discovered in neuroscience.
What about mnemonics? Is seems to be the elephant in the room and nobody studies why we remember things much faster if we use mnemonic "tricks".
+Jon Wise Mnemonics is using pre memorised circuit for memorising : so it goes faster.
Let me explain a bit. Remeber much of the time memory is constructed by associations of things u already know. The language for example is a pre memorized circuit to tell every kind of story. If you learn a tragedy in russian, a language you don't understant, then you just learn by spelling : very hard... Very, very hard. Now if u learn it in english, u'll find it way easier, and u'll do it faster. Because u master the mnemonics tool (the language) for telling this story.
Another derivative, is how a word is build within the language : a word is the memory and far heritage of a reaction, a feeling that u got the hability to express ones more by urself. In the language itself, each word is a mix of complex feelings and emotions memorised since years and years by humans... and shaped by ur sound expression capabilities. So words are maybe the most synthetic and direct correpondances to human feelings. A novel can be stored on 1Mo, when u need 1000 times more memory for a HD film that is maybe 6 times shorter than the novel. So mnemonics is also faster because it uses less memory space : space is pre organized... So u don't deal with all the solutions u could have to deal with, but only with those u allready know... and ur ancestor were allready confronted with.
WhichLens It makes sense. But why not at least use it to study memory since this give us a practical perspective on how something would effect learning if people were to use optimal strategies? E.g., let's say we give people some nootropic and test how it effects: a) speed of memorization b) speed of "memory decay" (i.e. how long memories will stay without repetition c) volume of facts people can remember before getting fatigued. Using mnemonics will increase: a) the volume of the test (people will be able to memorize lists of 100/200 items ); b) sensitivity of the test (it will be harder for people to accidentally recall something when they are not asked and accidentally strengthen that memory and introduce noise; it's hard to accidentally recall a set of 100 random items). c) make it useful since we'll have some data telling us about how much people can actually remember and it will tell them that e.g. on average at age N they can remember 100 words per hour per day using pure mnemonics, but if they exercise and have better diet and go something else (who knows perhaps we'll discover some drug or some intervention, e.g. perhaps tDCS will effect the score by a significant margin) it will lower the time needed to remember those 100 words at 95% accuracy at first recall.
E.g., I want to know if I'm going to remember 100 words per day in the fastest way possible, what that way would be? To me it's pretty clear that I would be using mnemonics, because I'm not aware of any other way to memorize that efficiently, but what to combine it with? How nootropics would effect the speed or whether they will work at all on healthy young individuals for this purpose? I'm interested in whether using neurofeedback and getting into a certain state would bring better results. Let's say that I train theta on certain part of the brain, will that promote better learning when combined with mnemonics? By how much?
Scientists do studies on how caffeine effect performance e.g. in high intense cycling. So if I'm a cyclist I can go and look that up. But if I want to learn in the fastest way possible, there is so little actually practical studies which tell me numbers. Add to that that most brain performance studies are done on not "healthy young individuals" but often on people with Alzheimer's disease , this is a pretty sad state of affairs .
And this to me is a pretty important question, if we were able to reduce education time by two (which is a very modest number) it would reduce 12/13 years to 6/6.5 years for children. With x4 efficiency increase that would reduce a time required to complete a Bachelors degree to just one year. A think this is a quite a practical question to ask, considering that people spend a lot of the time in their life learning no matter what age they are.

I'm no practitioner so sorry I can't help with the real world techniques. I
know brain is a kind of little lover that has his own sensitivity. So u
might be fast on certain subject and very slow on others, just because
ur brain is not excited by them. This is why humans get very
specialized : brain likes to construct from what it already knows, so
it can work very well if u start with something u like and just expands
with knowledges, skills, etc. For ur school performance question, I'd
say today, school is not about performance more about formating. The
goals of todays school is to deal with 90% of the solutions that as to
do with social organization and maybe 10% of useful knowledge. Our
school are not really knowledge oriented and professors start very young, just
upgraded bachelor, with very conventional knowledge : in human science
department, history I mean, I'd say the knowledge is wrong most of the
time, or not taught the way it should, so u could make something for
urself out of it. So one answer to ur question : yes, u surely could
reduce time to get the bachelors degree by cutting here & here things that
school programs want u to learn and that u will never use ! But will
have instead to forget if u're performance oriented. That is not the
same picture for university, where u can choose where to go. But beware
of professors, like said Richard Nixon in a fury ! Univerties in USA are kind
of private sector (even if State university, somewhere State is private sector in USA) :
so u know where u put ur foot in. Do not disturb industry with anti-productive knowledges,
or try to find a pleasant and social (business oriented) way to present them.
General answer to the memory perf question is two stage for me.
First, u memorize what u like to. Second, memorizing a lot helps u to
memorize (understand) new things.
But a performance is not made of just one kind of memory : as this
video shows, u have a lot of different memory families and a real
performer uses every family of memory to achieve its goals, to make
the all experience fun... u know, like a Christmas tree.
So what ever we're in, I think we should never forget the Christmas tree.
