Selective Stimulation of the Spinal Cord Surface Using a Stretchable Microelectrode Array

Selective Stimulation of the Spinal Cord Surface Using a Stretchable Microelectrode Array

By electrically stimulating the spinal cord, it is possible to activate functional populations of neurons that modulate motor and sensory function. One method for accessing these neurons is via their associated axons, which project as functionally segregated longitudinal columns of white-matter funiculi (i.e., spinal tracts). To stimulate spinal tracts without penetrating the cord, we have rece...

Stretchable microelectrode array using room-temperature liquid alloy interconnects

In this paper, we present a stretchable microelectrode array for studying cell behavior under mechanical strain. The electrode array consists of gold-plated nail-head pins (250 μm tip diameter) or tungsten micro-wires (25.4 μm in diameter) inserted into a polydimethylsiloxane (PDMS) platform (25.4 × 25.4 mm2). Stretchable interconnects to the outside were provided by fusible indium-alloy-filled...

Selective Stimulation and Measurement in the Cochlear Nucleus with the Spike Microelectrode Array

Current prosthetic devices to restore hearing sense of patients with bilateral acoustic neuromas aren’t always effective, because we don’t have sufficient knowledge of the auditory pathways and the Cochlear Nucleus (CN) functions to stimulate the Cochlear Nucleus functionally. Our goals are to enhance our understanding of such functions and to develop effective stimulating strategies of the CN....
