In a first, scientists map complete brain activity during decision-making

Mice moving tiny steering wheels to control shapes on a screen have given scientists an unprecedented view of how decisions unfold across the brain. For the first time, researchers have mapped decision-making at single-cell resolution across an entire mammalian brain. Traditional neuroscience studies have often focused on small clusters of neurons in isolated brain regions. But “the brain is constantly making decisions during everyday life,” said Ilana Witten, Ph.D., a neuroscience professor at Princeton University. “We’ve come to realize that there are many brain regions, rather than just one or two,...
