FMRI Studies of Visual Categorization in The Human Brain
Alexander Huth, et.al., at the University of California, Berkeley, have demonstrated how five human subjects, each viewing over two hours of movie clips, were each scanned by functional Magnetic Resonance Imaging instruments. Each brain scan recorded blood flow in thousands of individual locations, across their respective brains. Principal components analysis of regularized linear regressions revealed 1700 visual categories of 30,000 locations in cortex. Huth et.al. found highly organized, overlapping maps that occupied over 20% of cortex.

Famous quotes containing the words studies, visual, human and/or brain:
“Even if one studies to an old age, one will never finish learning.”
—Chinese proverb.
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
“History can predict nothing except that great changes in human relationships will never come about in the form in which they have been anticipated.”
—Johan Huizinga (1872–1945)
“The shepherd is the brain behind the dog’s brain,
But his control of dog, like dog’s of sheep
Is never absolute—that’s the beauty of it.”
—Cecil Day Lewis (1904–1972)
