Using magnetic fields, scientists can activate specific brain cells in mice and make them run, spin and freeze, new research shows.
This could help scientists pinpoint the specific brain circuits animals use for certain behaviors, which could in turn help scientists pinpoint with greater accuracy which brain areas are involved in those same behaviors in humans, said Arnd Pralle, a biophysicist at the University at Buffalo in New York.
The main goal is to develop tools that can help scientists study the brains of laboratory animals to see how they encode emotions and behaviors, Pralle told Live Science. "We can translate a lot of that to human brains," he added.
