Face Recognition Needs 3 Areas Of Human Brain
sushant_bhatia_progr writes "Nature has an article on the recent discovery that face recognition in humans targets 3 areas of the human brain. Using mugshots of celebrities, Pia Rotshtein at University College London and her colleagues have shown that there are at least three separate areas for processing and recognising faces. One processes the physical features of the face, one decides whether or not the face is known, and a third retrieves information about that person, such as their name. Rothstein's team used a computer to create a series of images in which the countenance of film star Marilyn Monroe gradually morphed into that of former British prime minister Margaret Thatcher, or that of James Bond actor Pierce Brosnan transformed into current prime minister Tony Blair."
Gotta love having enough celebs with mugshots to run an entire research experiment. :)
"Rothstein's team used a computer to create a series of images in which the countenance of film star Marilyn Monroe gradually morphed into that of former British prime minister Margaret Thatcher, or that of James Bond actor Pierce Brosnan transformed into current prime minister Tony Blair."
And the fourth part of the brain. Recognizing the horror of it all.
Marilyn Monroe gradually morphed into that of former British prime minister Margaret Thatcher
Whoever though of that is one sick scary F***er!!!
... it's pretty clear that Tony Blair has been morphing into Thatcher for years.
Shame he doesn't have her balls, though.
IAAfA (I am an fMRI analyst) Of course, the last highly publicized study that gave us a "face recognition area" of the brain turned out to be a crock. The same haemodynamic response came from birdwatchers seeing birds, or car experts seeing cars. It was a cognitive recognition area, not just a "face recognition area". I wouldn't be suprized if this experiment had the same falicies (article wasn't very precise).
Modularization: Great for OO programming, crappy for the human brain.
True it is no surprise that the three intuitive components of face recognition (see, recognize, identify) show activation in different regions of the brain. But these type of "it's obvious & intuitive" comments follow many scientific discoveries, especially those in psychology, and entirely miss the point of the experimental method - to prove (or disprove) those intuitions.
