Repairing Bad Memories
[Daniela Schiller] explained how recent research, including her own, has shown that memories are not unchanging physical traces in the brain. Instead, they are malleable constructs that may be rebuilt every time they are recalled. The research suggests, she said, that doctors (and psychotherapists) might be able to use this knowledge to help patients block the fearful emotions they experience when recalling a traumatic event, converting chronic sources of debilitating anxiety into benign trips down memory lane. And then Schiller went back to what she had been doing, which was providing a slamming, rhythmic beat on drums and backup vocals for the Amygdaloids(previously), a rock band composed of New York City neuroscientists.[more inside]
The Deep Mind of Demis Hassabis - "The big thing is what we call transfer learning. You've mastered one domain of things, how do you abstract that into something that's almost like a library of knowledge that you can now usefully apply in a new domain? That's the key to general knowledge. At the moment, we are good at processing perceptual information and then picking an action based on that. But when it goes to the next level, the concept level, nobody has been able to do that." (previously: 1,2) [more inside]

Dr. David Eagleman, a neuroscientist at Baylor College of Medicine, wanted to find out how the human brain processes time in a near death situation. [more inside]
Brain Researchers Open Door to Editing Memory : spotless minds might be closer than we think.
Dr. Joe Z. Tsien has previously created a strain of mice unable to form memories, one with much improved memory - "Doogie" mice - and can now erase single mouse memories. "Our work reveals a molecular mechanism of how that can be done quickly and without doing damage to brain cells." Remembering to forget....

Mapping Memory. "Turn the human brain upside down and all around to see how memories are saved (or lost)." National Geographic has a great interactive 3D map of the brain as part of an excellent feature on memory. [more inside]
