Hi there, it's Matt here and welcome back to the show. This one is rather special. In the past,

we've spoken a lot about how sleep is interrelated in an incredibly intimate way with learning and memory.

Of course, many of us assume that we understand this concept of memory, even just at a broad level, someone will say, I forgot something, what does that

mean? Or I am really good at remembering people's names, or I'm really bad at remembering people's names.

So we all speak about memory in a lay sense, but do we really understand it?

memory work? What is memory? And what are the implications once we really understand what memory is?

I wanted to bring on someone to do this with me because although I have spent probably a lifetime

feels like a lifetime in terms of my research career looking at memory in the context of sleep

there is someone who has such an astute in depth truly exceptional understanding of memory and human memory specifically.

And that is my guest today, Dr. Sharon Ranganath. He is a renowned neuroscientist. He is the

author of a book, a new book, which you should absolutely buy if you're fascinated by any of this.

The book is called Why We Remember, Unlocking Memories Power to hold on to what matters.

If you can remember my book, Why We Sleep, his is Why We Remember, and it's a brilliant, brilliant book.

In terms of credentials, Dr. Ranganath is the director of the dynamic memory lab at the University

of California, Davis.

And his groundbreaking research, I think it's fair to say.

It's really reshaped our understanding of how

human memory works specifically. Without further ado, welcome Dr. Ranganath and I will just go to the
