A Neuron's Obsession Hints at Biology of Thought

Researchers have discovered that in the vast neural network of the brain, some cells are, to use a technical term, celebrity groupies.

Probing deep into human brains, a team of scientists discovered a neuron roused only by Ronald Reagan, another cell smitten by the actress Halle Berry and a third devoted solely to Mother Teresa. Testing other single human neurons, they located a brain cell that would rather watch an episode of "The Simpsons" than Madonna.
