Today, an international team of researchers shared an extraordinarily detailed atlas of human brain cells, mapping its staggering diversity of neurons. The atlas was published as part of a massive package of 21 papers in the journal Science, each taking complementary approaches to the same overarching questions: What cell types exist in the brain? And what makes human brains different from those of other animals?
With hundreds of billions of cells tangled together, mapping the whole brain is like trying to plot every star in the Milky Way. (The inner workings of each cell are mini worlds of their own.) But just as better telescopes make the universe clearer to
