Dreams: the stuff memories are made of? (Part 2 of 2)
Listen Now - 07032009 |Download Audio - 07032009
Dreams feel meaningful—drawn from a mishmash of content from our waking lives. But it's a hot debate among scientists, who are yet to confirm why we sleep, let alone dream. Neuroscientist Matthew Wilson's extraordinary experiments involve eavesdropping on the sleeping minds of rats. He proposes dreaming is central to how we remember and learn.

Broadcast on The Science Show, ABC Radio National, 2009.
Maia Ten Brink is a senior high school student. She set out to determine the effects of sleep deprivation in cockroaches on memory retention. She taught her roaches to associate smells with tastes as rewards, then deprived them of sleep by movement through shaking. Over 4 days, the tired roaches demonstrated significant memory loss.Radio piece from WBUR takes you inside Wilson's experiments at MIT

Is your memory failing? Considered popping in a memory chip? Philosophical fantasies meet the world of the modern 'neural engineer' as All In the Mind ponders a curious future where brains are wired to computers, and silicon neurons replace your own. Scientists have just developed an early silicon model for an artificial hippocampus, a part of the brain so crucial to our sense of self. Its helps us make memories, and is often damaged in those with Alzheimers or after a stroke. But will these silicon recollections be your own?Nightmares: Scars of the Soul
