Increasing the optical transparency of a living mouse brain (and other nanotechnologies)
Many methods for increasing the optical transparency of non-living brain tissue have come into widespread use because of their utility in enabling better anatomical brain imaging. In the first part of this thesis, we explore whether this is also possible for living brain tissue. We report a general …
