Figuring out how hundreds of different kinds of brain cells develop from their unique expression of thousands of genes promises to not only advance understanding of how the brain works in health, but also what goes wrong in disease. A new MIT study that precisely probes this “molecular logic” in two neuron types of the Drosophila fruit fly shows that even similar cells push and pull many levers to develop distinct functions. In the study in Neuron, a team of neurobiologists at The Picower Institute for Learning and Memory found that the two…
