S…
Speaker 1 (sound)
You were once a completely different person.
0:02
S…
Speaker 1 (sound)
Not metaphorically.
0:03
S…
Speaker 1 (sound)
Literally.
0:04
S…
Speaker 1 (sound)
There was a version of you who existed for almost two years,
0:08
S…
Speaker 1 (sound)
who felt hunger and warmth and fear and joy every single day,
0:12
S…
Speaker 1 (sound)
and who is now gone.
0:14
S…
Speaker 1 (sound)
Not dead.
0:15
S…
Speaker 1 (sound)
Just unreachable.
0:16
S…
Speaker 1 (sound)
You will never get a single memory back from that person.
0:19
S…
Speaker 1 (sound)
And the strange part is,
0:21
S…
Speaker 1 (sound)
you probably never wondered why.
0:23
S…
Speaker 1 (sound)
Think about it for a moment.
0:25
S…
Speaker 1 (sound)
You can remember your fifth birthday party.
0:28
S…
Speaker 1 (sound)
Maybe not perfectly,
0:29
S…
Speaker 1 (sound)
but something is there.
0:30
S…
Speaker 1 (sound)
A cake,
0:31
S…
Speaker 1 (sound)
a room,
0:32
S…
Speaker 1 (sound)
a feeling.
0:33
S…
Speaker 1 (sound)
Go back further.
0:34
S…
Speaker 1 (sound)
Four years old.
0:35
S…
Speaker 1 (sound)
Three.
0:36
S…
Speaker 1 (sound)
Somewhere around there,
0:38
S…
Speaker 1 (sound)
the lights go out.
0:39
S…
Speaker 1 (sound)
Before that point,
0:40
S…
Speaker 1 (sound)
there is nothing.
0:41
S…
Speaker 1 (sound)
Not darkness,
0:42
S…
Speaker 1 (sound)
not blankness,
0:43
S…
Speaker 1 (sound)
just an absence where memories should be.
0:46
S…
Speaker 1 (sound)
Scientists call this infantile amnesia,
0:49
S…
Speaker 1 (sound)
and almost every human being on Earth experiences it.
0:52
S…
Speaker 1 (sound)
But here's the strange part.
0:54
S…
Speaker 1 (sound)
Babies are not blank.
0:56
S…
Speaker 1 (sound)
From the moment they're born,
0:58
S…
Speaker 1 (sound)
they're learning at a staggering rate.
1:00
S…
Speaker 1 (sound)
They recognize their mother's voice.
1:02
S…
Speaker 1 (sound)
They form preferences.
1:04
S…
Speaker 1 (sound)
They build the neural architecture that will define how they think for
1:08
S…
Speaker 1 (sound)
the rest of their lives.
1:09
S…
Speaker 1 (sound)
So why does none of it stick?
1:11
S…
Speaker 1 (sound)
For a long time,
1:12
S…
Speaker 1 (sound)
the answer seemed obvious.
1:14
S…
Speaker 1 (sound)
Babies just don't have the brain power yet.
1:17
S…
Speaker 1 (sound)
Their brains are still developing.
1:18
S…
Speaker 1 (sound)
Surely memory is one of the last things to come online,
1:22
S…
Speaker 1 (sound)
right alongside walking and talking.
1:24
S…
Speaker 1 (sound)
That answer is wrong.
1:26
S…
Speaker 1 (sound)
And the real explanation is far stranger than babies can't
1:30
S…
Speaker 1 (sound)
remember.
1:30
S…
Speaker 1 (sound)
Let's start with what memory actually is.
1:33
S…
Speaker 1 (sound)
When scientists talk about memory,
1:35
S…
Speaker 1 (sound)
they usually split it into two broad types.
1:38
S…
Speaker 1 (sound)
There's implicit memory,
1:40
S…
Speaker 1 (sound)
which is the kind of memory that doesn't require conscious recall.
1:43
S…
Speaker 1 (sound)
Riding a bike,
1:45
S…
Speaker 1 (sound)
flinching at a loud noise,
1:46
S…
Speaker 1 (sound)
feeling comforted by a particular smell without knowing why.
1:50
S…
Speaker 1 (sound)
And there's explicit memory,
1:52
S…
Speaker 1 (sound)
which is the kind you can consciously access and describe.
1:56
S…
Speaker 1 (sound)
What you had for breakfast,
1:58
S…
Speaker 1 (sound)
your best friend's name,
1:59
S…
Speaker 1 (sound)
the moment you learn to read.
2:01
S…
Speaker 1 (sound)
Babies have plenty of implicit memory.
2:03
S…
Speaker 1 (sound)
A baby who has been startled by a dog will show fear around dogs later.
2:08
S…
Speaker 1 (sound)
Even with no conscious memory of the original event,
2:11
S…
Speaker 1 (sound)
that fear is stored.
2:12
S…
Speaker 1 (sound)
It's just stored in a part of the brain that doesn't produce a story you
2:16
S…
Speaker 1 (sound)
can tell.
2:17
S…
Speaker 1 (sound)
Explicit memory is different,
2:19
S…
Speaker 1 (sound)
and explicit memory depends heavily on a small,
2:22
S…
Speaker 1 (sound)
curved structure deep in the brain called the hippocampus.
2:26
S…
Speaker 1 (sound)
Think of the hippocampus as a kind of index card system.
2:29
S…
Speaker 1 (sound)
It doesn't store memories permanently itself,
2:32
S…
Speaker 1 (sound)
but it tags experiences and helps file them away for long -term
2:36
S…
Speaker 1 (sound)
storage elsewhere in the brain.
2:38
S…
Speaker 1 (sound)
Here's the twist.
2:40
S…
Speaker 1 (sound)
The hippocampus is actually fairly developed at birth.
2:42
S…
Speaker 1 (sound)
It's not fully mature,
2:44
S…
Speaker 1 (sound)
but it's far more functional than scientists once assumed.
2:47
S…
Speaker 1 (sound)
So if the hippocampus is working,
2:49
S…
Speaker 1 (sound)
even partially,
2:50
S…
Speaker 1 (sound)
why isn't anything getting filed?
2:52
S…
Speaker 1 (sound)
This is where one of the most important studies in this field comes in.
2:57
S…
Speaker 1 (sound)
Researcher Carol Peterson,
2:59
S…
Speaker 1 (sound)
who has spent decades studying childhood memory,
3:01
S…
Speaker 1 (sound)
found something unexpected when she interviewed young children about events
3:06
S…
Speaker 1 (sound)
from their early lives.
3:07
S…
Speaker 1 (sound)
The children could describe things that happened to them at two or three
3:11
S…
Speaker 1 (sound)
years old.
3:12
S…
Speaker 1 (sound)
In detail.
3:13
S…
Speaker 1 (sound)
But when researchers checked back years later,
3:15
S…
Speaker 1 (sound)
those same memories were often gone.
3:18
S…
Speaker 1 (sound)
The information had been there.
3:19
S…
Speaker 1 (sound)
It just didn't survive.
3:21
S…
Speaker 1 (sound)
So the problem isn't that babies fail to form memories.
3:24
S…
Speaker 1 (sound)
The problem is that the memories don't last.
3:27
S…
Speaker 1 (sound)
Something about the early brain prevents these memories from being preserved
3:31
S…
Speaker 1 (sound)
long term,
3:32
S…
Speaker 1 (sound)
even when they're initially encoded just fine.
3:35
S…
Speaker 1 (sound)
One leading explanation involves something happening at a furious pace
3:39
S…
Speaker 1 (sound)
in the early brain,
3:40
S…
Speaker 1 (sound)
neurogenesis.
3:42
S…
Speaker 1 (sound)
That's just a scientific way of saying the rapid creation of
3:46
S…
Speaker 1 (sound)
new brain cells.
3:47
S…
Speaker 1 (sound)
In most regions of the adult brain,
3:49
S…
Speaker 1 (sound)
neurogenesis slows to a crawl.
3:52
S…
Speaker 1 (sound)
But in early childhood,
3:53
S…
Speaker 1 (sound)
especially within the hippocampus,
3:55
S…
Speaker 1 (sound)
new neurons are being produced at an extraordinary rate.
3:59
S…
Speaker 1 (sound)
Researcher Paul Franklin,
4:01
S…
Speaker 1 (sound)
working with colleagues,
4:02
S…
Speaker 1 (sound)
proposed something fascinating.
4:04
S…
Speaker 1 (sound)
What if this flood of new neurons doesn't just add to the brain's storage?
4:08
S…
Speaker 1 (sound)
What if it actively overwrites it?
4:11
S…
Speaker 1 (sound)
Imagine a filing cabinet where new folders are being shoved in so
4:15
S…
Speaker 1 (sound)
quickly that old folders get crushed,
4:17
S…
Speaker 1 (sound)
shuffled,
4:18
S…
Speaker 1 (sound)
or destroyed in the process.
4:20
S…
Speaker 1 (sound)
In mice,
4:21
S…
Speaker 1 (sound)
Franklin's team found that artificially increasing neurogenesis in young
4:25
S…
Speaker 1 (sound)
animals caused them to forget things faster.
4:28
S…
Speaker 1 (sound)
And artificially slowing neurogenesis in older animals made memories
4:32
S…
Speaker 1 (sound)
stick around longer than expected.
4:34
S…
Speaker 1 (sound)
If something similar happens in human infants,
4:37
S…
Speaker 1 (sound)
it would mean your earliest memories weren't lost because they were
4:41
S…
Speaker 1 (sound)
too weak to form.
4:42
S…
Speaker 1 (sound)
They were lost because your brain was rebuilding itself so rapidly that
4:46
S…
Speaker 1 (sound)
the old structures literally couldn't survive the renovation.
4:49
S…
Speaker 1 (sound)
But neurogenesis isn't the whole story.
4:52
S…
Speaker 1 (sound)
There's another piece,
4:53
S…
Speaker 1 (sound)
and it has to do with something you don't have yet as a baby.
4:57
S…
Speaker 1 (sound)
A sense of self.
4:58
S…
Speaker 1 (sound)
Memory isn't just about storing information.
5:01
S…
Speaker 1 (sound)
It's about storing information in relation to you.
5:05
S…
Speaker 1 (sound)
A memory needs a main character to attach itself to.
5:08
S…
Speaker 1 (sound)
Researcher Katherine Nelson has argued that autobiographical
5:12
S…
Speaker 1 (sound)
memory, the kind where you remember things as events that happen to you,
5:17
S…
Speaker 1 (sound)
requires a child to first develop a concept of self as
5:21
S…
Speaker 1 (sound)
someone who exists continuously through time.
5:23
S…
Speaker 1 (sound)
Before that sense of self solidifies,
5:26
S…
Speaker 1 (sound)
around the time language really takes off,
5:28
S…
Speaker 1 (sound)
experiences may simply have nowhere to attach.
5:31
S…
Speaker 1 (sound)
There's no narrative thread yet for them to become part of.
5:35
S…
Speaker 1 (sound)
This is why language matters so much here.
5:38
S…
Speaker 1 (sound)
Once children start forming sentences,
5:40
S…
Speaker 1 (sound)
they start forming narratives.
5:42
S…
Speaker 1 (sound)
I went to the park.
5:44
S…
Speaker 1 (sound)
I was scared.
5:45
S…
Speaker 1 (sound)
Mommy left and came back.
5:47
S…
Speaker 1 (sound)
These aren't just descriptions.
5:49
S…
Speaker 1 (sound)
They're scaffolding.
5:51
S…
Speaker 1 (sound)
They give experiences a shape that can be stored,
5:53
S…
Speaker 1 (sound)
retrieved,
5:54
S…
Speaker 1 (sound)
and retold.
5:56
S…
Speaker 1 (sound)
Before language develops,
5:57
S…
Speaker 1 (sound)
an experience might be felt intensely in the moment,
6:00
S…
Speaker 1 (sound)
but it has no scaffold to hang on.
6:02
S…
Speaker 1 (sound)
And without that scaffold,
6:04
S…
Speaker 1 (sound)
it dissolves.
6:05
S…
Speaker 1 (sound)
So picture your earliest years like this.
6:08
S…
Speaker 1 (sound)
Your brain is under construction.
6:10
S…
Speaker 1 (sound)
New neurons are pouring in,
6:12
S…
Speaker 1 (sound)
restructuring the very systems that would normally hold memories in place.
6:16
S…
Speaker 1 (sound)
At the same time,
6:18
S…
Speaker 1 (sound)
the you that memories would belong to hasn't fully formed
6:22
S…
Speaker 1 (sound)
yet.
6:23
S…
Speaker 1 (sound)
There's no stable narrator to file these experiences under.
6:26
S…
Speaker 1 (sound)
The combination is almost perfectly designed to erase everything,
6:30
S…
Speaker 1 (sound)
no matter how vividly it was experienced in the moment.
6:33
S…
Speaker 1 (sound)
Here's where it gets even stranger.
6:36
S…
Speaker 1 (sound)
Even though you can't recall those years,
6:38
S…
Speaker 1 (sound)
they didn't disappear without a trace.
6:40
S…
Speaker 1 (sound)
Remember implicit memory?
6:42
S…
Speaker 1 (sound)
That system was running the whole time,
6:45
S…
Speaker 1 (sound)
quietly building your foundations.
6:47
S…
Speaker 1 (sound)
The way you respond to stress as an adult.
6:50
S…
Speaker 1 (sound)
The kinds of voices or environments that make you feel safe without knowing
6:54
S…
Speaker 1 (sound)
why.
6:55
S…
Speaker 1 (sound)
Certain instinctive reactions to comfort,
6:57
S…
Speaker 1 (sound)
to closeness,
6:59
S…
Speaker 1 (sound)
to fear.
6:59
S…
Speaker 1 (sound)
Much of this may have roots in those first wordless years.
7:03
S…
Speaker 1 (sound)
You're not carrying around memories from that time.
7:06
S…
Speaker 1 (sound)
You're carrying around the results of them.
7:08
S…
Speaker 1 (sound)
This connects to something deeper about what memory is even for.
7:12
S…
Speaker 1 (sound)
Memory isn't a video recorder.
7:14
S…
Speaker 1 (sound)
Faithfully capturing your life for later viewing,
7:17
S…
Speaker 1 (sound)
it's a survival tool.
7:19
S…
Speaker 1 (sound)
Its job is to extract patterns,
7:21
S…
Speaker 1 (sound)
lessons and useful information from experience and to discard
7:25
S…
Speaker 1 (sound)
the raw footage once the lesson has been absorbed.
7:27
S…
Speaker 1 (sound)
For an infant,
7:29
S…
Speaker 1 (sound)
the lessons being absorbed are enormous.
7:31
S…
Speaker 1 (sound)
How to form attachments,
7:33
S…
Speaker 1 (sound)
how to regulate emotion,
7:34
S…
Speaker 1 (sound)
how to trust or not trust the world.
7:37
S…
Speaker 1 (sound)
Once those lessons are baked into the architecture of the brain,
7:41
S…
Speaker 1 (sound)
the original footage of how they were learned becomes unnecessary.
7:45
S…
Speaker 1 (sound)
The brain isn't malfunctioning by deleting it.
7:48
S…
Speaker 1 (sound)
It's doing exactly what memory is designed to do,
7:51
S…
Speaker 1 (sound)
just at a stage of life where the lessons matter more than the record.
7:55
S…
Speaker 1 (sound)
There's a modern mirror to all of this,
7:57
S…
Speaker 1 (sound)
and it's closer than you might think.
7:59
S…
Speaker 1 (sound)
Think about how differently you remember a chaotic week versus
8:04
S…
Speaker 1 (sound)
a calm one.
8:05
S…
Speaker 1 (sound)
During periods of intense change,
8:06
S…
Speaker 1 (sound)
moving to a new city,
8:08
S…
Speaker 1 (sound)
starting a new job,
8:09
S…
Speaker 1 (sound)
going through a major life transition,
8:12
S…
Speaker 1 (sound)
time often feels like it's flying by,
8:14
S…
Speaker 1 (sound)
and yet looking back,
8:16
S…
Speaker 1 (sound)
those periods can feel strangely thin in memory,
8:19
S…
Speaker 1 (sound)
full of gaps.
8:20
S…
Speaker 1 (sound)
Some researchers believe this is because,
8:22
S…
Speaker 1 (sound)
much like in infancy,
8:24
S…
Speaker 1 (sound)
your brain is busy reorganizing itself to adapt,
8:27
S…
Speaker 1 (sound)
and that reorganization competes with the process of laying down stable,
8:31
S…
Speaker 1 (sound)
long -term memories.
8:33
S…
Speaker 1 (sound)
In a much smaller,
8:34
S…
Speaker 1 (sound)
much gentler way,
8:35
S…
Speaker 1 (sound)
you're echoing what happened during your first two years.
8:38
S…
Speaker 1 (sound)
Rapid change.
8:40
S…
Speaker 1 (sound)
A self still adjusting to a new context.
8:42
S…
Speaker 1 (sound)
And memories that don't quite take root the way they normally would.
8:46
S…
Speaker 1 (sound)
So the next time you try and fail to remember anything from
8:50
S…
Speaker 1 (sound)
before you were three,
8:51
S…
Speaker 1 (sound)
don't think of it as a flaw.
8:53
S…
Speaker 1 (sound)
Don't think of it as something missing.
8:56
S…
Speaker 1 (sound)
Think of it as evidence of just how much work your brain was doing during those years
9:00
S…
Speaker 1 (sound)
worked so intensive that it had to clear away the construction debris to
9:04
S…
Speaker 1 (sound)
make room for what came next.
9:06
S…
Speaker 1 (sound)
You weren't there to witness the foundation being poured,
9:09
S…
Speaker 1 (sound)
but you're standing on it right now.
