A newly designed ion channel allows scientists to use magnetic fields to force neurons to fire in animals’ brains. The channel joins a growing number of tools that are helping researchers map neural circuits and understand the roles different cells play in the brain.

To tease apart the daunting complexity of the brain, neuroscientists have developed techniques to activate or silence specific neurons. One such method, optogenetics, controls neurons with light but requires fiber optics . . .
