Efficiency of endoneural stimulation with 5- to 24-fold multielectrodes [PDF]

open access: yes, 1998
Optimal selective stimulation of nerve with endoneurally (intrafascicularly) inserted multi-microelectrodes means that each electrode activates, with its own threshold stimulation current, as few distinct motoneurons as possible, preferably only one, If ...
