Show Summary Details


This chapter discusses voltage-activated ion channels in glial cells, including sodium channels, calcium channels, and potassium channels. Studies have proven that glial cells contain a large variety of voltage-gated channels that are also commonly found in neurons. However, unlike their neuronal counterparts, these channels do not appear to be engaged in generating short-duration transient electrical signals, but are most likely involved in other fundamental cell biological functions.

Keywords: glial cell; sodium channel; calcium channel; potassium channel
