bring your brain on-line

. . . the human brain can be visualized as a complex interacting network that relies on nodes to efficiently convey information from place to place. Very few jumps are necessary to connect any two nodes . . .

"This so-called 'small world' property allows for the most efficient connectivity," said Dante Chialvo, a physiologist at Northwestern University. Other networks -- social and biochemical -- rely on the same principle.
