"Lee thinks that her technique – optogenetic fMRI combined with computational modeling – gives researchers a new way to reverse-engineer the functions of the many different types of neurons in the brain and the bafflingly diverse array of neural circuits formed to carry out different commands." If that's true, this could be huge.
