Stimulus modality lit area, the eyes require time for a good quantity of rhodopsin to regenerate. As more time passes, there is a higher chance that the photons will split an unbleached photopigment because the rate of regeneration will have surpassed the rate of bleaching. This is called adaptation. Humans are able to see an array of colours because light in the visible spectrum is made up of different wavelengths (from 380 to 760 nm). Our ability to see in colour is due to three different cone cells in the retina, containing three different photopigments. The three cones are each specialized to
Retinal precursor cells Wnt11 is localized in the center of the developing retina and is suggested to play a role in precursor cell differentiation. This expression coincides with the fact that committed cells are located in the center of the developing retina while undifferentiated cells are concentrated in the periphery Fz5 expression is implicated in differentiation of retinal precursor cells to a neural fate. Retinal precursor cells Retinal precursor cells are biological cells that differentiate into the various cell types of the retina during development. In the vertebrate, these retinal cells differentiate into seven cell types, including retinal ganglion cells, amacrine cells, bipolar
