  • In the past doctors would infer where the problem wass by the symptoms. They would then open the brain and see if they were right
  • Now: Brain organization -> functional connectivity
  • Functional MRI measures blood flow
  • Diffusion Tensor Imaging the only method for imaging tensors
  • Combine fMRI with MEG or fMRI with MRI
  • VR to prepare for operation
  • AR to help annotate points of interest on the brain
  • The relationship in the brain of where things are locate and how they relate to other places in the brain is important

    • Cross-department funding for another workshop?

James V. Koch

  • Risk: You know the probabilities
  • Uncertainty: You don’t
  • Privately profitable vs. society
  • Recent inovations started from individuals, not big companies
  • National Labs work better when in cooperation with universities
  • Lesson learnt: Get people together and let them work on what they think
  • Profit motive makes people more productive
  • When to sell intellectual property, since imitations will arise soon
  • Lessons
    • Outside funders are skeptical
      • they look at the diffusion curve (uncertainty)
      • they want equity
    • Need substantial amount of equity to participate
    • Very high discount rates because of uncertainty
    • Investors require control
    • Try to get some benefits for the decision makers early on since they will not be there for too long
      • Don't sell out before benefits
