Mapping the Mind

Harvard scientist Jeff Lichtman wants to build a full map of the mind by carving off slivers of a mouse brain and passing the portions through a powerful electron microscope.

Dr. Jeff Lichtman likes his brains sliced thin—very, very thin. Dr. Lichtman and his team of researchers at Harvard have built some unusual contraptions that carve off slivers of mouse brains as part of a quest to understand how the mind works. Their goal is to run slice after minuscule slice under a powerful electron microscope, develop detailed pictures of the brain’s complex wiring and then stitch the images back together. In short, they want to build a full map of the mind. The field, at a very nascent stage, is called connectomics, and the neuroscientists pursuing it compare their work to early efforts in genetics.

Why American history lives between the cracks

The stories we tell define history. So who gets the mic in America?

  • History is written by lions. But it's also recorded by lambs.
  • In order to understand American history, we need to look at the events of the past as more prismatic than the narrative given to us in high school textbooks.

Juice is terrible for children. Why do we keep giving it to them?

A glass of juice has as much sugar, ounce for ounce, as a full-calorie soda. And those vitamins do almost nothing.

Surprising Science
  • Orangutan mothers wait to sound a danger alarm to avoid tipping off predators to their location
  • It took a couple of researchers crawling around the Sumatran jungle to discover the phenomenon
  • This ability may come from a common ancestor
