First Wiring Diagram of Mouse Brain Created

April 2, 2014

The brain is an incredibly complex organ. The tiny mouse brain, for example, contains over 86 million neurons, each with over 1,000 different connections, clustered in different groupings. In a sense, the neural networks resemble a complex highway system between cities. To navigate the brain, researchers are going to need some maps, and two of the most detailed maps have just been created.
