"Memory Hackers," from PBS's NOVA documentary strand, takes a look at cutting edge research into the nature of memory, and how it might be manipulated for the benefit of mankind.
"For much of human history, memory has been seen as a tape recorder that faithfully registers information and replays it intact," say the film's creators.
"But now, researchers are discovering that memory is far more malleable, always being written and rewritten, not just by us but by others. We are discovering the precise mechanisms that can explain and even control our memories."
