Learning and Memory: How it Works and When it Fails


(March 9, 2010) Frank Longo, MD, PhD, George and Lucy Becker Professor, discusses the intricacy human mind and how different types of memory and memory loss function.

Stanford Mini Med School is a series arranged and directed by Stanford’s School of Medicine, and presented by the Stanford Continuing Studies program.

  1. Have your Oxygen saturation level upon waking in the morning, as if it is too low, it will affect your retention of short term memory!

  2. I was unable to retain any information for longer than 5 Minutes, didn't find out why until my 20th year, lack of oxygen saturation, that was my first 20 years had my doctor refer me to a sleep lab, that discovered my oxygen level upon waking in the morning, was at the same level as an olympic athlete, that had just completed a marathon?? They then placed me on C-Pap, and within a year, a normal memory began to emerge!
    But through it all I became extremely organized, and as well, I developed a Learning System, that consisted of 1. reading 4 pages a night of any information, and this would place the information, into my long term memory and remain there forever! 2. I developed a subliminal method, that Placed any desired information onto Cassettes, and rig the cassette player to turn on at 1: AM, and turn off at 4:AM and this places any information from the cassettes, into my long term memory! where it would remain forever!

  3. I don’t remember my dad,but he buggered off before I was 4 weeks old,case closed.re opened lol,for some odd reason I remember him as being a sad pathetic loser,the memory is a strange thing,you can’t trust it,remember this.the dr says,we record new memory to the brain,I don’t think we do,I think their is a,let’s say,demo list,of various pain,sounds,images,to fill in memories to suit.you see your kid a birthday party in a memory,great,what shoes did he have on,you don’t know,but he has shoes on,added thanks of your memory demo list.as we get older the demo list grows,reality fades.

  4. A moment to moment consciousness might be the "here and now" of buddhism. Why is it soo bad not to remember the past if you can be immersed in the present?

  5. Mr. Wearing seems to have a rather selective loss of declarative long-term memory. Language, recognition of objects, speech, semantic, grammar all seem to be intact. Things that apparently involve Medial Temporal Lobe and Diencephalon. whose damage however seems to have wiped out episodic (Event) memory??

  6. In this lecture there is talk about short term memory and long term memory as if they were in different places in the brain. This would imply that memories have to be transferred from short term memory into long term memory and then deleted from short term memory to free up space.

    There is another possible explanation and that it that the sensory inputs will result in short term memory if not consolidated and long term memory if they are consolidated by repetition but is the same neural pathways that are involved. It is just that the same neural pathways comprising a particular memory change from short term to long term by habituation.

    The crucial role of the focus of attention in storing memory is mentioned in the lecture. The neural network brain function associated with focus of attention is proposed in this paper:


  7. hello, I am 45 years old, I have recently tried to memorize many
    Algorithm cases for solving 3×3 rubiks cube, each algorithm tackles a
    partial solving state that targets a particular position on the cube.
    Exampe of 1 case: [(y') U2 R2' U2 R U R' U R2]
    then I move on to the next partial solve. and so forth, I have managed
    to know such algorithms from my memory and can find them and even write
    them down, but what troubles me is the practical side of implementing
    these tasks. they are memorized but not memorized enough to be
    practically used. What other attributes/additionals of long term memory
    can be useful to me.

  8. Great video, but is kinda off putting hearing people laugh when they are told that people can't remember things….

  9. Thank  you Frank Sir … I love brains & processors.  Wouldn't it be nice if we can Augment our innate(inborn) brain to much higher form? like exocraneal cap implant(transistors and neurons working together) like "neurochips".

  10. The Cicero and Dante quotes are profounder than the empirical explanations and  speculations. But good and informative lecture.

  11. This makes me want to go to Stanford, they seem like amazing professor's, down to earth but high in the pursuit of excellence. 🙂

  12. Whoa! Very informative by Sir Frank Longo, thank you Sir for your sharing and that the brain is not boring. Your closing on the movements of brain is brilliant. I enjoyed every sec of your presentation. God bless you and your work. 

  13. your advertising on this site is stupid and inappropriate. I hope people ignore you. I should have but I am annoyed how you are exploiting some other person's good work. You are a parasite. And probably being scammed by pyramid marketing that punishes the person at the bottom. When the US economy crashes, what real skill have you got?
