This hour of Radiolab, a look behind the curtain of how memories are made...and forgotten.

Remembering is an unstable and profoundly unreliable process--it’s easy come, easy go as we learn how true memories can be obliterated, and false ones added. And Oliver Sacks joins us to tell the story of an amnesiac whose love for his wife and music transcend his 7-second memory.

Eternal Sunshine of the Spotless Rat

What is a memory? Science writer Jonah Lehrer tells us is it’s a physical thing in the brain… not some ephemeral flash. It’s a concrete thing made of matter. And NYU neuroscientist Joe LeDoux, who studies fear memories in rats, tells us how with a one shock, one tone, and ...

Adding Memory

We start this section off with a question from writer Andrei Codrescu: "where do computers get their extra memory from?" And then we take it literally. Can you add memories? Dr. Elizabeth Loftus says yes. She’s a psychologist in the department of Criminology, Law and Society at ...

The story of a man who’s lost everything. Clive Wearing has what Oliver Sacks calls “the most severe case of amnesia ever documented.” Clive’s wife, Deborah Wearing, tells us the story along with Oliver Sacks. And they try to understand why, amidst so much forgetting, Clive remembers two things: Music ...

Is it possible that you can create a false memory by your self.

Nov. 14 2017 07:35 PM

Ok, I understand this as applying to personal memory but where does "knowledge" fit in? If I remember something that I learned from a text book and I answer correctly on a test or even years later in practice where is that stored and is that different than my memory of a specific event?

Great episode! :)
May I ask: where could I access the article mentioned that was published 2 years before the film Eternal Sunshine of the Spotless Mind was out?

It is interesting to know the knowledge about how memory are made. I wonder that memory is really amazing and people can get a lot of help with a good memory. I really want to know more about that.

I wonder how to account for those rare people who seem unable to forget, as one of them put it. They remember virtually every moment of their lives. There was a woman I heard interviewed who kept a detailed diary. You could ask her what she did on, let's say, Sept 3rd 1973, and she could tell you. You could match to her diary, and it would turn out to be true.

Memory is not just a physical brain activity. Memory is an experience. I was very curious to hear about the first kiss concept, each time you remember the first kiss, the memory gets more and more clouded with changes over time.

A filing cabinet is my memory; I believed it at first and was surprised the scientists said no to it. Then the hard drive analogy, which they said it was wrong. I agree that memory is more creative than either of those solid objects; it’s not as simple as a filing cabinet or a hard drive. The goldfish example was great; it proves that proteins are the key to memory. The background sounds when speaking of construction of a rat’s memory was very helpful to fully understanding the example. It was also funny to me to hear the speaker to say “ohh, what’s that.. ow!” I also found it supplemental to have the actual scientist there to explain the experiments and the reasons behind them. Does this conditioning work the same with humans? I would think that it does when we are children but I wonder if it works as humans. They say it works to erase memories in a way through drugs and it erodes the memory and that is great to help PTSD but there will always be controversy about it. They say you are recreating the memory at some point and does this make our memories deceiving and false? I really enjoyed this NPR because of how thought provoking it was, I have always wondered about the mysteries of memory and I feel that my curiosity has been tamed. I still hope to learn more and I will look out for more memory pod casts.

Has anyone watched the 3rd episode (season1) of the show Black Mirror? In this episode a piece of memory technology called a "seed" is in use by most people. The episode explores in a most fascinating way what the affect of never forgetting anything might be on relationships. This episode has haunted me for the past few days. Seriously good stuff.

So when a memory is relived over and over, it is rebuilt again and again.

Apply this to the Middle East. This is a great summary of 4000 years of the Middle East.

Could it be that cultures that can't "get over it" are great story-tellers and can't get over it because they can't stop reliving events?

From Sanders "This article, like so many since the 90's on NPR and PBS, are just more crafting of a postmodern view of reality that appeals to the corporate and 1%. Trying make people accept the fact that one's memories are unreliable, is not accurate journalism, it's purposeful spin."

Do you have any idea what you are talking about? Post-modern spin? One of the few things that has been demonstrated since 1909 is the constructive nature of memory. The belief that they are snapshots is not simply a philosophical debate -- it is a well-tested empirical fact. And the testing precedes the notion of post-modernism.

Have some knowledge about the facts prior to opining. I won't even go near the incredibly vague connection between the substantive topic and the political views you somehow managed to weave together. Way to stay on point (another PBS show -- perhaps you can try that one).

This article, like so many since the 90's on NPR and PBS, are just more crafting of a postmodern view of reality that appeals to the corporate and 1%. Trying make people accept the fact that one's memories are unreliable, is not accurate journalism, it's purposeful spin. Wouldn't "Big Brother" just love for the commoners to question what happened yesterday and accept whatever comes in the future as normal? What crap.

Example? Thursday or Friday night (can't remember the exact day!!! hah!!!) on PBS Nightly News during an article on the Gaza slaughter, one woman reporter asked if there isn't someway to get Hamas to stop shooting missiles, as if this would stop Israel. Facts. Hamas was promoted by the Israelis as an alternative to Fatah ("According to Zeev Sternell, historian at the Hebrew University of Jerusalem, "Israel thought that it was a smart ploy to push the Islamists against the Palestinian Liberation Organisation (PLO)"). There are up to 15 political parties in Palestine and many small rebellious groups that no one can control. The stated goal of Israel is a state free of all Palestinians (Chomsky among many have documented proof of this). I can go on here, but truth is PBS and NPR avoid any exhaustive journalism and keep syncopated to all corporate media feeding people gibberish. NPR is not what is was back in the 70's.

There are experiences that point to a quite different idea of memory. It's well known that people who come close to death, by drowning especially, sometimes see their "entire life flash before them". George Ritchie, whose near-death experience is described in "Return from Tomorrow", gives a good description of an experience of this kind while separate from his physical body, which was lying in a bed with a sheet pulled over it. So the memories were not in that body.

The esoteric teacher Rudolf Steiner actually said this "memory tableau" was one of the experiences everyone has after death, one lasting about three days. He gave a good short explanation in his book "An Outline of Esoteric Science", in the chapter "Sleep and Death". It comes, he said, when the soul has separated from the physical body, but is still connected to the etheric or life body. This latter dissolves after about three days, ending the experience.

I was very curious to hear about the first kiss concept, according to which each time you remember the first kiss, the memory gets more and more clouded with changes over time. Like another of your listeners, this made me think about autism, and more specifically of the autistic twins Flo and Kay, who clearly remember everything in their past, and can not only tell you what they did on any given day, but what they wore. Why does this clouding of memory not seem to happen to them? Great show, as always. :)

Re the assertion that our original memory is lost and we remember memories of it -- and that they increasingly diverge away from the original memory and towards something we invent:
I agree with the first part, and don't argue that the second part isn't often the case, but I have experience showing the diverging can be significantly limited.
When I was maybe four years old and my brother was nine, he told me that people usually forget things that happened when they were small kids, but I could keep memories I wanted to save, by remembering them whenever I thought about doing so. He added that I wouldn't have the original memories but memories of them. I don't know how he got that information, but we've both practiced it over the years, going over our caches of memories when we think of doing it. A test of how accurate the retained memories were came up about 1996, when I came across a map of a community we'd lived in till it was flooded out of existence in 1948 (Vanport, Oregon). It was large enough scale to show the many multiplex apartment buildings as well as other features. We both picked the same exact site for where we'd lived, I by referring to a nearby playground and radio tower, he by using other things.
I highly recommend this method. I know it works for kids, and while I can't give evidence it works for adult memories, I rather think it does.

Memory is not simply physical brain activity. Memory is an experience. Neuroscience conveniently (how else to query non-linguistic beings?) ignores that and focuses on some of the potentially physical aspects that go into making memory an experience. They then (psychology is guilty of this a well) adopt a simplistic causal model (memory is stored experience from one's past that subsequently is retrieved to influence thought and/or behavior). Of course, by this simplistic assertion, almost all cortical function terminates in memory (imagination, belief, thought....) save for strictly regulative activity. And the word memory becomes a meaningless designation.

Memory is the experience of stored (often greatly modified content), not, as psychology will tell you, the content experienced. And experience (mental experience) may be physical (e.g., Strawson, 1994) or not, but it is not reducible to current psychical conceptions of neural activity (Nagel, 1986; Klein, 2014). Maybe someday, but that will entail (require) a new definition of "physical law" and such is not on any rational horizon.

Radiolab needs to get some actual memory experts on the show -- though they would need to pick carefully, lest they continue to propagate pop conceptions of topics like self and memory.

I expect more from PBS.

As a forensic artist since 1995 I've been dealing with the memory of eyewitnesses as they try and describe the face of the perpetrator. In 1996 I made a decision to eliminate the use of reference images to create a composite sketch after reading the research done by Dr. Loftus and the work by Fisher and Geiselman. Over the years I have been impressed with the work of Dr. Wells, from Ohio University, as he explains the dangers of eyewitness misidentification. My police agency and the district attorney adopted many of the photo line-up changes suggested by his work. Now my attention has been directed to the research on done on the brain and the science behind what we think we remember. It has given me more confidence in every cognitive interview I conduct without reference images. I hope that other forensic artists and law enforcement commanders around the country listen to this episode and begin to discuss the best practices in interviewing eyewitnesses.

Memory is such an odd thing.

In high school a boy I knew fell down a flight of stairs and had very serious head trauma, after which he could no longer remember anything that happened before he woke up that morning, everyday, so he had to keep a diary of all the important things he did and learned that day so he could read about them later.

One day he asked to read something out loud that I had handwritten. At a specific point he stumbled because he couldn't read my handwriting, and it was the only point that happened. That made me very curious, and I figured it wasn't something important enough to write in his diary. The next day, I gave him the same writing and asked him to read it out loud, not mentioning that he'd done it the day before. His recitation was exactly the same as the day before, with no variations, one single stumble and all.

I asked him what happened if he simply didn't got to sleep one night; was he able to remember everything that happened until the next time he went to sleep? He said he never tried. Unfortunately, we weren't very close friends so I didn't talk to him again after high school. I wonder if he'd found out the effect of pulling an all-nighter, and if he ever got his memory persistence back.

Really interesting episode! I never knew something like Eternal Sunshine of the Spotless Mind could be real!! Love RadioLab. :-)

Jun. 10 2013 11:46 AM

Here's the thing. I googled "best radiolab episodes" and this came up. So I listened to it. It took me 15 minutes to realize that I had already listened to this 3 months ago. Most likely because 3 months ago I googled the same string.

Here's the memory and all it's mysteries.

Jun. 06 2013 02:52 PM

You know, I'm a big fan of documentaries and typically I would be the first to say that the best documentaries (Made for TV that is) almost always come from the BBC (Horizon amongst others comes to mind). But I have to confess that I'm literally in awe of the depth of presentation/material for this program. This stuff is so well put together that to be honest its much better than documentaries I've seen on the same subject from the BBC (stressing on "SEEN"). This program to me, has managed to paint a picture so clear in my minds eye that in many ways, its actually much more engaging and more entertaining than "Seeing" it. That first segment "Eternal Sunshine Of the Spotless Rat" completely blew me away.. And really got me thinking about why its necessary for the brain to always reconstruct memories from scratch. What.. does the brain "Load-Shed" for capacity issues or is it necessary for the integration of an event into our consciousness so that it can be associated with other stuff in our mind and ultimately become "YOU" (during sleep maybe..).
It really got me thinking.. and you know.. even though that segment ended on a bit of a somber note, I actually got something slightly different out of what was mentioned. Because in a sense, its actually strangely more interesting and personal that way. I mean, if we remembered events verbatim then memories would be almost like an insect trapped in amber that you can't really interact with and possibly learn from. Maybe it would have made us Spock-like where memories become nothing but sterile facts to be regurgitated on a whim or as "a matter of fact".
The fact that the memory over time becomes more about you I think, in a sense, is OK because it happened TO you.. as opposed to it happening in an ethereal space where it is simply observed.. Memories being malleable in nature makes the memory in sense "Alive" as opposed to sterile..

Needless to say, RadioLab and its presenters are awesome because I never think about this stuff typically..

For those out there interested in issues of memory and identity, this podcast featuring philosophy professor Carl Craver, who works with amnesia cases, is really fascinating: (Full disclosure: I conducted the interview and produced the show.) Hope some of you can listen in!

I am an acupuncturist and have found a very effective non-drug way to break or disconnect emotions from memories much like the drugs mentioned in the broadcast. It is called pstec and is available for a free download. It breaks the neural pattern that links the emotions with a pattern interrupt technique. I recommend it highly. Hope this helps someone. - Dan

A l o h a ! To all, from the sunny slopes of Haleakala on Maui.

It is such a pleasure to look forward to 2 P.M. on Saturdays because that's when RadioLab comes on the translater station KIPM-FM (of KIPO-FM, Honolulu).
The topics are always approached in a serious, yet offbeat, manner and their fact-finding missions yield surprising results.
Like this one on...Uh, what was it on, again? Oh, oh, yeah - MEMORY. What a plastic thing the concept of mind is, consciousness is still a hotly debated issue when it comes to providing definitions, and how we flex our mnemonic muscles differs greatly also.
The Declaration of Consciousness made to allow invertebrates (such as cephalapods; octopuses, squids, and cuttlefish) to be deemed as thinking creatures with an awareness of themselves and all else implied might be a good subject for a future show.

Words can in no way describe what a beautiful idea it is to contemplate. I know much of my brain time will be spent on this topic and its many implications. What does this do regarding the credability of a person's recollection of something he claims he witnessed? "I swear I saw John kill his wife!" "Objection, your honor. Who can say whether or not his memory has been erased or changed."

"Honest, Dear. You don't see me in bed with Trixie, Bubbles and JoAnn. I think your memory isn't working correctly. Now please appologise to them right now while they are putting their clothes back on."

I was very dismayed to hear a program that was based on the torture of rats. It is a moral outrage that such experiments were conducted. Then, to hear people discuss the animals' suffering with utter insouciance was chilling.

I second what Jon from Madison and Dierda form Vermont both say. Jon does not believe it is the memory itself that is erased by the drugs, and suggests it may be the feeling connection to the memory. Dierda raises the question about healing from PTSD: if one tempers with the memory, does one lose the benefits from healing?

I am a counselor and my specialty is to help people heal from difficult memories and rediscover their passion and aliveness. I agree that people can get further and further away from the original memory by thinking about it a lot. My goal as a counselor is healing. A memory is attached to sensations in the body. So when I ask people to tell me about the memory that is haunting, hurting, or obsessing them, I wait until they are ready to face their truth, and then I ask that they forget the actual story and experience what is going on in their body in that moment from the story they just told me.

I guide them to accept that energy by embracing it and giving it space, instead of fighting it as we usually do by fear of it. By embracing the energy, it moves and is eventually released. It is not unusual that a forgotten original story is remembered with heartfelt emotions. It is felt from the perspective of the person experiencing it at the time, not colored by those other people present. That is the difference with the memory they usually first start telling me. When we take on other people's interpretation, we typically make ourself wrong and we disconnect from ourself.

So when a piece of the original story comes to the surface, a true reconnecting with oneself happens. In my experience, nothing is more healing because it is the separation from being able to love who we are when a traumatic experience happens that is the real source of trauma, it is not the event itself. That is why we can heal. When the people I work with are able to feel for the first time the event from their own perspective at the time of the event, they are able to love themselves as never before and they can also forgive whoever else was involved. The result is a newly found freedom. What it is they find depends on what they gave up then.

I am wondering of the use of a drug to alleviate the effect of a memory. I would want to know if I could still guide people who used such a drug to find the gifts lost by a traumatic memory, or if the drug can give them back to themselves the way my work can. I suspect the original memory is not erased.

My work also tells me the memory is in the body, not in the brain. The remembering happens in the brain. So that explains why the lady with amnesia and whose doctor greeted her shaking her hand with a tack pricking her skin, reacted the next day before shaking his hand, even if she consciously did not remember ever meeting her doctor. What appears to be affected in amnesia is not the memory but aspects of the path to it. The problem is in the brain. The memory is in the body.

Jon from Madison, WI

I don't believe that the drug you talk about erased any memory. All because the mouse didn't react to the beep does not necessarily mean it lost a memory. You may be confusing FEELINGS and memory. Just like the woman that got raped as a child. She didn't forget the memory, but her feelings about it changed. I did not read the research, but what was said on RadioLab is not convincing enough to make me believe the drug erases memory. Can someone clarify this?

I never get tired of hearing the story of Clive. I suffer from an increasing forgetfulness myself, so I find his story especially compelling -- the sense that our very "humanness" can only exist through the virtue of memory. In a sense, we are what we've experienced. Without the memory of experiences, we collapse to the existence of a stone, or as Clive said -- death.

I get teary every time I hear his story.

As someone who is working diligently to heal from PTSD, I wonder about the drug that removes memory.

This program indicating that memories are recreated every time they are recalled and are also changed every time they are remembered seems to have at least one frightening consequence.

Crime witnesses told to remember and repeat their memory of a crime could have it changed every time by police or attorneys.

Not sure why this episode does not even mention photographic memory and got more in depth about musical memory.
Also some individuals have extremely accurate memories and can't forget anything.
Especially people with autism or asperger syndrome.
I suggest a follow-up episode going more in depth.

Not surprisingly Music is something that Clive can't forget.
Music and sounds and hearing have the most immediate and direct connection to our emotions.

Like i wrote in your comment section: "RE-play. The fact that people, "scientists" would rather fuck around messing with the sensetivities of innocent animals, rather than spending that time learning how to be quality human beings makes me sick."
I'm pissed,that you would even entertain the idea of enabling this kind of behavior towards animals by including it in your radio show ,in such a way, no matter what the 'justifications' are. I am disgusted, by this; and humans's feeling of entitlement towards,relying on animals to quench,their inine curiosity,and validate their college degrees and self worth.
If people would spend the time they do harrassing innocent animals and grow some balls, maybe they would actually,get people,to mourn and heal traumas from the past,like humans are supposed to do, rather than sidestepping,those issues ,and extending uneccesary suffering by projecting it on animals.

I heard a podcast the other day that I believe was somewhat old. I'm not entirely sure of the exact date but I think it was posted within the last year. It was about a man who could remember virtually everything he had ever encountered and had synesthesia. There was another man involved who also had synesthesia and was entered into a world memory championship but lost. Does anyone by any chance know the podcast I'm thinking of? If so please tell me the name. Thanks.

Neither of these two theories is quite accurate. Elizabeth Loftus has done some groundbreaking work, but in terms of what actually happens in the brain, it would be worth checking out the concepts of pattern separation and pattern completion. Because memory cannot by nature be acontextual, it makes more sense that memories would be stored and retrieved in this "pattern" format. Nobody's really trying to interfere with somebody's life (no brainwashing), but really trying to understand the function of this essential element of the human experience.

If memories can only be recreated, then theoretically you could only ever remember something by accident. There has to be something holding the "blueprints" for these creations.

Maybe its a mixture of the filing room theory and the recreation theory, and administering that drug at the right time just completely severs any link to where that memory is located. It would be like having a shortcut to a program on your desktop, but having no path to the file.

Boy, talk about memory. The comment below (the best to my recollection) is better understood by going to the "Limits" episode and listeing to "Limits of the Mind". It was the story of Mr. S .

I recall a story about a noted memory expert able to recall an extraordinary amount of "things", forward, backward or randomly. He would travel around displaying his unique ability. In addition, he was studied by those in the scientific field, pushed to the limit of memory. He never failed to amaze. To make a long story short, he eventually "flipped his wig". He no longer could form or hold his OWN thoughts without a flood of previous things remembered constantly bombarding his individual thoughts or ideas. These memories never stopped. Just imagine a hughe and endless amount of data interrupting you own thoughts to the point where you lose yourself, forever.
I believe this story is from "This American Life", if not here at Radiolab.

I loved this program and searched to find the podcast. It says so much about how and why we remember as we do. Both disappointing and facinating.

Ugh. I'm trying to listen to this radiolab from school, but it's so hard to stay attentive to it. The background noises and people talking over each other make it so difficult to concentrate.

To my understanding they are treating the brain like some thing out of a scifi movie. They are using all different kind of methods to figure out the brain and its functions. I do believe that they are messing with GOD creation and we are soon going to be walking around like robots. Memory is a part of the brain and taking pills to see if ones memory can relocate might be a bit for fetch. Trying to erase memorys or inplant memory i think can be damaging. Scientist will always want to explore the imposibilties.
