Memory

http://www.radiolab.org/story/91569-memory-and-forgetting/

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.

Joe LeDoux: If you give a drug to a goldfish. It can't make a memory. Jonah Lehrer: It's a physical thing. Not simply an idea. A physical trace made of proteins. They know because they did a test on rats. Where they have a associating connection between a tone and a shock. But if you inject a chemical in the brain that prevents these neurons of forming a memory, they'll never remember. If you get to the memory on the moment it's made you can bust it up. But if the protein bridge is there already you can not change it.. That's what they thought. Karim Nader: What will happen if you give it when it's remembering?
