This new project sounds like it is the neuroscientific analog of LHC or the Human Genome Project. The truth is that we wouldn't be able to replace the LHC with 1000 synchrotrons.
I would be much happier if this project was focusing on creating the LHC equivalent in brain mapping w.r.t. instrumentation and methods.
For instance, a cheaper imaging technology that offered 2-3x the resolution of current techniques. That would be a much more focused goal and would have clear benefits for all scientists working in these areas.
