First, all seven of the basic retinal cell types have been identified and well characterized (Fig. 1) (3). Rod and cone photoreceptors respond to light, and transmit signals to bipolar cells.

The origin of retinal bipolar cells Retinal bipolar cells share a large repertoire of features with rod and cone photoreceptors. Structurally, retinal bipolar cells have the same 'bipolar' shape ...

Bipolar cells left without a connection to a photoreceptor start to grow new branches, called dendrites. This image shows two S-cone bipolar cells (marked by *) contacting the same S-cone axon ...

This observation is puzzling for two reasons: photoreceptors are known to use graded ‘analog’-type signals to ... (2015) Dopamine modulation of rod pathway signaling by suppression of GABAC feedback ...
