<p>For the first time ever, an international team of researchers has created a complete cell atlas of a whole mammalian brain. This atlas serves as a map for the mouse brain, describing the type, location, and molecular information of more than 32 million cells and providing information on connectivity between these cells. The findings were funded by <a href="https://braininitiative.nih.gov/">the National Institutes of Health’s<em> Brain Research Through Advancing Innovative Neurotechnologies</em>® Initiative</a>, or The BRAIN Initiative®, and appear in a collection of 10 papers published in <em>Nature</em>.</p>
