Huberman Lab · How to Improve Your Memory & Cognitive Function at Any Age | Dr. Alan Castel · 13 Jul 2026 podcast

This is going to be like an internal memory that I can take.

And hopefully it lasts forever.

Well, you know, memory is reconstructive.

And I think, you know, the more you retrieve it and go back there, the more you'll have this feeling of remembering it.

And our brain does a lot of interesting things in terms of, you know, reconstructing the past also has a similar brain signature as imagining the future, which, you know, in some ways makes sense.

We shouldn't have separate parts of the brain for thinking about the past and thinking about the future.

but that can kind of then predict why you might misremember something, why your imagination has to be based surely on the experiences you've had already.

Right?

Or, you know, if I say, what would it be like to go to Mars?

Well, you've never been to Mars, but you've seen movies in the past about it.

So our, you know, if I said imagine a space alien, you and I being similar age are probably going to think of the ET version of one.

Whereas someone who's younger than us might have a very different kind of representation of that.

So it's interesting to think of memory as kind of a reconstruction of the past, but also imagining the future involves, you know, our past experiences.

You know, I don't think we muck it all up and I don't think we do it intentionally either.

But as a result of all the information we have in our memory, we're constantly interpreting, you know, the future and our current state.

And you spoke a little bit about eyewitness memory.

I think that's a really good example of that where something horrible might have happened.

And like your experience where you think you're taking a picture and you're going to remember everything.

And it feels like you will.

I can remember the shirt.
