Cone Cell

The Cone Cells in the human retina are responsible for detecting color.  Different cone cells have different types of photopsins that are sensitive to specific wavelengths of light.  Cone cells are more prevalent in the center of the retina and need high levels of light to detect color.  Like the rod cells, cone cells transduce stimuli from the environment into electrical and chemical signals.  The enameling represents depolarization of the cone cell, which lead to neuronal firing.
