Definition

The principal primary active transport system in neurons, the Na/K-ATPase utilizes energy to maintain cation cellular concentrations by extruding Na and accumulating K ions, thus creating an electrical potential across the neuronal cell membrane. It is estimated that 25 to 40% of brain energy utilization may be related to Na/K-ATPase activity. Abnormalities in the pump may lead to neuronal dysfunction, although the exact relationship to familial hemiplegic migraine is not known.
