title: [Studies on potassium transport through glial cell membranes (author's transl)].
abstract: The retina of the honeybee drone is used as a model for the study of ion movements across the membranes of the glial cells caused by changes in the extracellular potassium concentration. The values found for changes in extracellular potential suggest that at least some of the potassium that enters glial cells in an active region of tissue is associated with an efflux of potassium from parts of the glial syncytium not affected by an increase in extracellular potassium concentration. In addition, it appears that ions other than K+ cross the glial membrane.
