A neuron extends an axon to make contact with other neurons. A team of more than 100 scientists recorded the cellular activity and mapped the structure in a cubic millimeter of a mouse's brain. Los científicos lograron "un hito" al trazar la actividad y estructura de 200.000 células del cerebro de un ratón y sus 523 millones de conexiones. A neuron extends an axon to make contact with other neurons.

Chun-Hsiang Chang, a paleontologist at Taiwan's National Museum of Natural Science, first learned of the jaw in 2010 from a private collector. Inspecting it, he could tell right away that it did not belong to a gorilla. Gorillas and other apes have U-shaped jaws. Instead, the fossil jaw angled outward from the chin, as our jaws do. But the jaw lacked the prominent chin found in today's humans. "At that time, I thought it looked like a human, but not a modern human," Dr. Chang said.

The human brain is so complex that scientific brains have a hard time making sense of it. A piece of neural tissue the size of a grain of sand might be packed with hundreds of thousands of cells linked together by miles of wiring. In 1979, Francis Crick, the Nobel-prize-winning scientist, concluded that the anatomy and activity in just a cubic millimeter of brain matter would forever exceed our understanding. "It is no use asking for the impossible," Dr. Crick wrote.
