galvanotropism -->
medical dictionary

<physiology> The directed movement of cells induced by an applied voltage. This movement is almost always directed toward the cathode, occurs at fields around 1 mV/mm and is argued to be involved in cell guidance during morphogenesis and in the repair of wounds.

The term galvanotropism is used for neurones, since the cell body remain stationary and the neurites grow toward the cathode. Note that these processes involve cell locomotion and are distinct from cell electrophoresis.
