It could instruct neuronal maturation, allowing already-born photoreceptors to express ... A: TRβ2 mutants have a defect in opsin expression. Normally, cones in the dorsal retina express more ...

This is a confocal microscope image of rod and cone photoreceptors in a human retina. Fluorescent probes have been used to identify rod photoreceptors (green) and cone photoreceptors and ...

Here, the color-sensitive cone photoreceptors allow us to detect even the smallest details. The density of these cells varies from person to person. Additionally, when we fixate on an object ...
