neurons

Santiago Ramón y Cajal's drawings of nerve cells changed scientists' understanding of the brain. Now, 80 of those drawings are going on display at an art museum in Minnesota.

When people saw photos that linked a famous person with a famous place, it changed the behavior of certain neurons in their brains. And it changed their memories, too.

Researchers in Seattle are busy cataloging what scientists have learned. For now that includes detailed information on 240 mouse cells. Next up: a data trove of details on human brain cells.

Scientists are still better than computers at assessing a neuron's health by looking at its shape. But an effort that includes an international series of hackathons could help speed the process.
