U.S. researchers are hopeful that human trials on a revolutionary memory implant will be fruitful. Scientists say that the implant could help people restore the memories of people who have had a stroke or suffered localized brain injury. MAURICIO LIMA/AFP/Getty Images
The researchers are focusing on the hippocampus -- the place in the brain where short-term memories are made into long-term memories. In a separate study, Stanford University researchers recently created an 3-D animation (pictured) that renders the hippocampus region of a mouse brain transparent. Stanford University
