Rewiring the Brain to Treat OCD Dr. Jeffrey Schwartz got a phone call at 3 p.m., a script before 5 p.m. and the next afternoon he was there, sitting with Leonardo DiCaprio, exploring the intricacies of one of the most debilitating mental illnesses in medicine. DiCaprio was tackling the role of Howard Hughes in The Aviator, a part requiring him to arc — as Hughes did — from genius billionaire to shaggy recluse, caught in the grip of obsessive-compulsive disorder.
researchers discover molecular determinant of cell identity Steve Fisch Howard Chang and his team have discovered how cells decide which proteins they will tend to produce. If a big bunch of your brain cells suddenly went rogue and decided to become fat cells, it could cloud your decision-making capacity a bit. Fortunately, early in an organism’s development, cells make firm and more-or-less permanent decisions about whether they will live their lives as, say, skin cells, brain cells or, well, fat cells.
Manipulating Memory For psychologist Alain Brunet, the case is still astonishing. When Patrick Moreau first came into his office suffering from post-traumatic stress disorder (PTSD), the Canadian soldier, who had served as a United Nations peacekeeper in Bosnia, could hardly bear to recount the details of the day he was taken hostage in 1993. The memory–of kneeling on the ground with his hands on his head, legs shaking, a stark line of trees across the sky–aroused crippling fear that felt as fresh as it had 15 years before. The glimpse of a particular tree line through his windshield was enough to bring the memory rushing back, giving him such violent shakes that he would have to pull off the road. But six months after participating in Brunet’s clinical trial, Moreau no longer meets the diagnostic criteria for PTSD.
Complicity and the Brain: Dynamics in Attractor Space Dr. Peter Henningsen firstname.lastname@example.org Abstract: This paper outlines a research program that is intended to look for the emergence of consciousness in computers. How consciousness works – Michael Graziano Scientific talks can get a little dry, so I try to mix it up. I take out my giant hairy orangutan puppet, do some ventriloquism and quickly become entangled in an argument. I’ll be explaining my theory about how the brain — a biological machine — generates consciousness.
The Big Chandra Picture The Big Chandra Picture In more than a decade of operation, NASA's Chandra X-ray Observatory has transformed our view of the high-energy Universe with its ability to make exquisite X-ray images of star clusters, supernova remnants, galactic eruptions, and collisions between clusters of galaxies. As Chandra expands the realm of the known, it continues to raise new questions and point the way for future exploration. This photo blog presents some of Chandra's most spectacular images in a large and shareable format. Gut feelings: the future of psychiatry may be inside your stomach Her parents were running out of hope. Their teenage daughter, Mary, had been diagnosed with a severe case of obsessive–compulsive disorder (OCD), as well as ADHD. They had dragged her to clinics around the country in an effort to thwart the scary, intrusive thoughts and the repetitive behaviors that Mary felt compelled to perform. Even a litany of psychotropic medications didn’t make much difference.
First habitable exoplanet confirmed Gliese 581d is the outlying planet in the Gliese 581 system, and orbits its parent star every 66.8 days. It may be covered by a large and deep ocean and is the first serious 'waterworld' candidate discovered beyond our Solar System. Credit: ESO/L. Calçada Neuroscientist Daniela Schiller is Researching Ways that Bad Memories Can be Made Less Fearsome It was a Saturday night at the New York Psychoanalytic Institute, and the second-floor auditorium held an odd mix of gray-haired, cerebral Upper East Side types and young, scruffy downtown grad students in black denim. Up on the stage, neuroscientist Daniela Schiller, a riveting figure with her long, straight hair and impossibly erect posture, paused briefly from what she was doing to deliver a mini-lecture about memory. She 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.
SeenAndShared.com The Law Of The Wild says "Kill ONLY when you are hungry." Photographer Michel Denis-Huot, who captured these amazing pictures on safari in Kenya's Masai Mara in October last year, said he was astounded by what he saw: *UPDATE: While these pictures are indeed real, the outcome after the encounter below did not fare well for the young deer.
