But the structure we can recreate in models is an approximation of the real one. Neurons can be visualized under microscopes and reconstructed using computer programs. One of HBP's goals is to model neurons as 3-dimensionally detailed cells. These shapes are not just for show neurons process signals differently depending on their structure. They extend short and long processes, which branch out in different patterns. Where are the gaps in our knowledge and why might they present problems?Īn artificial brain must start with good building blocks. But many neuroscientists argue we don't know enough about the brain to model it. Henry Markram, says they can realistically simulate a human brain within 10 years. This is the concept behind the Human Brain Project, recently awarded 1 billion euros by the European Commission as one of two Future and Emerging Technologies Flagships Initiatives. Computers offer promise if we could build an artificial brain that behaves likes a real one, maybe we could pick it apart to see how it works. Our understanding of it is fragmented, and hindered because, except rarely, we can't get inside and look around while it is still functioning.
