Binge eaters' dopamine levels spike at sight, smell of food - 1 views

  •  
    ScienceDaily (Feb. 28, 2011) - A brain imaging study at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory reveals a subtle difference between ordinary obese subjects and those who compulsively overeat, or binge: In binge eaters but not ordinary obese subjects, the mere sight or smell of favorite foods triggers a spike in dopamine -- a brain chemical linked to reward and motivation.

Trafton Drew: Why Even Radiologists Can Miss A Gorilla Hiding In Plain Sight - 0 views

  •  
    "He then asked a bunch of radiologists to review the slides of lungs for cancerous nodules. He wanted to see if they would notice a gorilla the size of a matchbook glaring angrily at them from inside the slide. But they didn't: 83 percent of the radiologists missed it, Drew says. This wasn't because the eyes of the radiologists didn't happen to fall on the large, angry gorilla. Instead, the problem was in the way their brains had framed what they were doing. They were looking for cancer nodules, not gorillas. "They look right at it, but because they're not looking for a gorilla, they don't see that it's a gorilla," Drew says. In other words, what we're thinking about - what we're focused on - filters the world around us so aggressively that it literally shapes what we see"

But the reason why butterflies congregate onto the turtles may be stranger than you think: to drink their tears. The butterflies are likely attracted to the turtles' tears because the liquid drops contain salt, specifically sodium, an important mineral that is scant in the western Amazon, said Phil Torres, a scientist who does much of his research at the Tambopata Research Center in Peru and is associated with Rice University.

How the brain recognizes objects - 0 views

  •  
    "Researchers at MIT's McGovern Institute for Brain Research have developed a new mathematical model to describe how the human brain visually identifies objects. The model accurately predicts human performance on certain visual-perception tasks, which suggests that it's a good indication of what actually happens in the brain, and it could also help improve computer object-recognition systems."
