Abstract

The authors have developed a neural interface, the Utah Slant Array (the USA), that provides unprecedented access to a large number of sensory and motor neurons. The array has been designed to be implanted into fascicles of peripheral nerves, and it provides up to 100 channels of neural communication. The authors are currently evaluating the recording and stimulation capabilities of the USA in acute experiments in cat sciatic nerve. Very high selectivity even for high forces can be reached by near simultaneous stimulation of two or more electrodes innervating the same muscles. The authors suspect that, using the same methods, fatigue resistant stimulation is also possible
