These two functions are separate for Rb and in this study we further characterize the role of Rb in retinal development. At postnatal day 12 in the retin...

Traditionally, such facilitation has been understood to be a consequence of nonlinear contrast transduction. Facilitation has also been reported to arise from non-overlapping patterns ...
