Genes give neurons a 'GPS' to form the brain's neural circuits, scientists show

How complex neural circuits are genetically designed and wired is a fundamental question in neuroscience. Scientists have shown for the first time that genes encode a "wiring map" that guides neurons to connect with the correct brain regions. The findings, based on machine learning analysis of mouse brain data, were published in the Proceedings of the National Academy of Sciences, and offer new avenues for research into brain development and disease.
