Abstract

Work with ion-selective microelectrodes on the retina of the honeybee drone has shown that potassium is released from photoreceptors during activity and enters glial cells. Measurements of the extracellular voltage gradients indicate that, in this preparation, currents flowing through the glial cells in the ‘spatial buffer’ pattern account for a large fraction of the glial K+ entry in the active region of the tissue.
