The chromatin in the nucleus of rod photoreceptors has an inverted structure in nocturnal animals. Metabolically, this is expensive to maintain, so it has been proposed that the inverted architecture provides an advantage during night vision. Subramanian et al could show with our OptoDrum that the inverted nuclear architecture provides improved contrast sensitivity in dark environments.
