Memory Banda’s life took a divergent path from her sister’s. When her sister reached puberty, she was sent to a traditional “initiation camp” that teaches girls “how to sexually please a man.” She got pregnant there — at age 11. Banda, however, refused to go. Instead, she organized others and asked her community’s leader to issue a bylaw that no...

The mind is a diligent recorder, taking note of all that happens and storing data on it for retrieval later, right? Well actually, no. Enjoy these 7 illuminating talks on the science—and oddities—of our memory.

In many ways, our memories make us who we are, helping us remember our past, learn and retain skills, and plan for the future. And for the computers that often act as extensions of ourselves, memory plays much the same role. Kanawat Senanan explains how computer memory works. [Directed by TED-Ed, narrated by Addison Anderson, music by Carlos Pal...

In memory of a great man and the numbers he loved.

Think back to a really vivid memory. Got it? Now try to remember what you had for lunch three weeks ago. That second memory probably isn't as strong— but why not? Why do we remember some things, and not others? And why do memories eventually fade? Catharine Young gives the basics on memory and memory loss. [Directed by Patrick Smith, narrated by...

"Music can unlock a frozen memory that melts into the seeds of our creativity," says musician Rosanne Cash. Reflecting on the power of memory, solitude and community, she performs "The Sunken Lands" and "Particle And Wave" and meditates on some of life's most poignant and bittersweet themes.

Psychologist Elizabeth Loftus studies memories. More precisely, she studies false memories, when people either remember things that didn't happen or remember them differently from the way they really were. It's more common than you might think, and Loftus shares some startling stories and statistics -- and raises some important ethical questions.

We've all been told to get a good night's sleep before a test -- finally, here's the reason why. Sleep scientist Matt Walker explains how getting enough sleep affects how our brains store and process memories.

Memory Banda is a tireless leader for girls’ rights, in Malawi and around the world.

How do you turn a memory, especially one of a traumatic event, into hard evidence of a crime? Julia Shaw is working on this challenge, combining tools from memory science and artificial intelligence to change how we report workplace harassment and bias. She shares three lessons to apply if you've been harassed or discriminated against -- and int...

There are people who can quickly memorize lists of thousands of numbers, the order of all the cards in a deck (or ten!), and much more. Science writer Joshua Foer describes the technique -- called the memory palace -- and shows off its most remarkable feature: anyone can learn how to use it, including him.

Using examples from vacations to colonoscopies, Nobel laureate and founder of behavioral economics Daniel Kahneman reveals how our "experiencing selves" and our "remembering selves" perceive happiness differently. This new insight has profound implications for economics, public policy -- and our own self-awareness.

Joshua Foer is a science writer who 'accidentally' won the U.S. Memory Championship.

Can you cram for a test while you sleep? Our intrepid neuroscientists attempt to enhance memory by running experiments on subjects while they sleep. You'll be surprised by the results.

In his groundbreaking work, Xu Liu investigated how to activate and deactivate specific memories in mice.

You spend weeks studying for an important test. On the big day, you wait nervously as your teacher hands it out. You're working your way through, when you're asked to define "ataraxia." You know you've seen the word before, but your mind goes blank. What just happened? Elizabeth Cox details the complex relationship between stress and memory. [TE...

One of the obstacles facing those who have experienced workplace harassment is the scarcity of reporting mechanisms that adequately combine fact-finding rigor with emotional support. Drawing from a decade studying police interviews and the ways trauma interacts with memory, Dr. Julia Shaw discusses how cognitive science and online tools can help...

Artist Sarah Sze takes us on a kaleidoscopic journey through her work: immersive installations as tall as buildings, splashed across walls, orbiting through galleries -- blurring the lines between time, memory and space. Explore how we give meaning to objects in this beautiful tour of Sze's experiential, multimedia art.

Memory-manipulation expert Elizabeth Loftus explains how our memories might not be what they seem -- and how implanted memories can have real-life repercussions.

Trauma and PTSD rewire your brain -- especially your memory -- and can unearth destructive emotional responses when stirred. Could we eliminate these triggers without erasing the memories themselves? Enter neurologist Amy Milton's mind-blowing, memory-editing clinical research poised to defuse the damaging effects of painful remembered experienc...

Have you ever misplaced something you were just holding? Completely blanked on a famous actor's name? Walked into a room and immediately forgot why? Neuroscientist Lisa Genova digs into two types of memory failures we regularly experience -- and reassures us that forgetting is totally normal. Stay tuned for a conversation with TED science curato...

Can we edit the content of our memories? It's a sci-fi-tinged question that Steve Ramirez and Xu Liu are asking in their lab at MIT. Essentially, the pair shoot a laser beam into the brain of a living mouse to activate and manipulate its memory. In this unexpectedly amusing talk they share not only how, but -- more important -- why they do this.

"Life comes at us very quickly, and what we need to do is take that amorphous flow of experience and somehow extract meaning from it." In this funny, enlightening talk, educational psychologist Peter Doolittle details the importance -- and limitations -- of your "working memory," that part of the brain that allows us to make sense of what's happ...

When Henry Molaison (now widely known as H.M.) cracked his skull in an accident, he began blacking out and having seizures. In an attempt to cure him, daredevil surgeon Dr. William Skoville removed H.M.'s hippocampus. Luckily, the seizures did go away — but so did his long-term memory! Sam Kean walks us through this astonishing medical case, det...

These TED Talks push us to question more -- our doctors, our governments and even our own eyes.

Admit it, lasers are pretty cool. Discover the awesome, ingenious ways these beams of light are being used to fight against malaria and HIV, scan ancient monuments ... and even edit memory.

How does a computer work? The critical components of a computer are the peripherals (including the mouse), the input/output subsystem (which controls what and how much information comes in and out), and the central processing unit (the brains), as well as human-written programs and memory. Bettina Bair walks us through the steps your computer ta...

When Steve Ramirez published his latest study in Science, it caused a media frenzy. Why? Because the paper was on implanting false memories in the brains of mice.

It's a common saying that elephants never forget. But the more we learn about elephants, the more it appears that their impressive memory is only one aspect of an incredible intelligence that makes them some of the most social, creative, and benevolent creatures on Earth. Alex Gendler takes us into the incredible, unforgettable mind of an elephant.
