Pannexin 1 Is Critically Involved in Feedback from Horizontal Cells to Cones
Frontiers in Molecular Neuroscience, 2017 Retinal horizontal cells (HCs) feed back negatively to cone photoreceptors and in that way generate the center/surround organization of bipolar cell receptive fields. The mechanism by which HCs inhibit photoreceptors is a matter of debate.
