Abstract

Glial cells in the retina play an important role in clearing light-evoked increases in potassium from extracellular space. Glial cells of the honeybee drone retina remove excess K⁺ by net uptake of the ion and by K⁺-mediated current flow through intracellular pathways. In the vertebrate retina, the high membrane conductance of the endfoot process of Müller (glial) cells directs excess retinal K⁺ into the vitreous humor.
