Radiolab from NPRs Morning Edition on fear memory

I've looked at the science of fear a lot here at PANIC!, so my ears perked up this morning when I started listening to this program on public radio this morning, about how fear memories alter one's sense of time. From the program description:

When Alice fell down the rabbit hole, her fall seemed to last forever. Neuroscientist David Eagleman had the same experience as an 8 year old boy while falling off a roof. This led him to wonder, what is it about brushes with death that cause this slow-mo effect? He now thinks he knows.

It's a fascinating program, well worth the seven minutes and change it takes to listen to.

During my search for the link to the program, I also came across this program, featuring NYU scientist Joseph LeDoux, about erasing fear memories, another topic I've discussed repeatedly on this blog. The program description:

What is a memory? Science writer Jonah Lehrer tells us is it’s a physical thing in the brain… not some ephemeral flash. It’s a concrete thing made of matter. And NYU neuroscientist Joe LeDoux, who studies fear memories in rats, tells us how with a one shock, one tone, and one drug injection, you can bust up this piece of matter, and prevent a rat from every making a memory. LeDoux’s research goes sci-fi, when he and his colleague Karim Nader start trying to erase memories. And Nader applies this research to humans suffering from PTSD. 

Good stuff; I particularly like the way the programs go into the philosophical implications of the science.
