Personalized Brain Medicine for the World’s Two Billion Neurological Patients

1 in 3 people is affected by a neurological condition — conditions we cannot cure or prevent if we do not understand the underlying cellular mechanisms. However, available human data at the cellular level are too limited to represent individual variation across the population. Centuries of neuroscience have sought answers about the brain's complexity, but the real challenge, and the main reason for the lack of progress in curing brain disease, is variability. Discovering the right treatments for individual patients requires understanding not only the human brain, but how human brains differ, and for that we need to examine thousands of brains microscopically.
