Our brain cells have different genomes from one another. The study shows for the first time that mutations in somatic cells -- that is, any cell in the body except sperm and eggs -- are present in significant numbers in the brains of healthy people. These mutations appear to occur more often in the genes a neuron uses most. Patterns of mutation allow researchers to trace brain cell lineages.
