Wireless control of nerve growth using bipolar electrodes: a new paradigm in electrostimulation.

Electrical activity underpins all life, but is most familiar in the nervous system, where long range electrical signalling is essential for function. When this is lost (, traumatic injury) or it becomes inefficient (, demyelination), the use of external fields can compensate for at least some functional deficits. However, its potential to also promote biological repair at the cell level is underplayed despite abundant evidence for control of neuron growth.
