Scientists at the Salk Institute have created a new model of memory that explains how neurons retain select memories a few hours after an event. This new framework provides a more complete picture of how memory works, which can inform research into disorders liked Parkinson's, Alzheimer's, post-traumatic stress and learning disabilities.
Using a video game in which people navigate through a virtual town delivering objects to specific locations, a team of neuroscientists from the University of Pennsylvania and Freiburg University has discovered how brain cells that encode spatial information form "geotags" for specific memories and are activated immediately before those memories are recalled.
People who are haunted by visions of war and scenes of violence sometimes wish they could remove the bad memories from their minds. Medical researchers at Johns Hopkins University think that it may be possible someday.
Neuroscientists at University College London have taken another step towards mind-reading. They have developed a computer algorithm which allows them to tell which of three short films a person is thinking about via a brain scan.
