title: Four photoreceptor types in the ground squirrel retina as evidenced by immunocytochemistry.
abstract: Previous morphological and electrophysiological data show that the ground squirrel retina consists of one rod and two different cone systems. In the present study, immunological evidence is presented that four different photoreceptor cell types are located in the retina of the European ground squirrel (Citellus citellus). In addition to the green and blue cones two rod-like photoreceptor cell types (types 1 and 2) can be distinguished using color specific anti-visual pigment antibodies.
