Most promising fields of neuroscience in the next 20 years?

What do you think are the most promising fields of neuroscience for the next +/- 20 years?

I feel like computational neuroscience might develop some breakthroughs, i feel like there’s only so much we can conclude from biochemical / mol. biological research alone so for fundamental insights, we’ll need mathematical/physical models as well. Functional imaging also seems like an interesting field.
