A High-Precision Bioelectric Neural Interface Toward Human-Machine Symbiosis
… bioelectronics underlying a new class of bioelectric neural interfaces that could bring us one step closer to this feat. We pioneer new circuit techniques, including frequency shaping (FS), redundant sensing (RS), RS-based super-resolution, and redundant crossfire (RXF), to enhance the …

Improving the mechanistic study of neuromuscular diseases through the development of a fully wireless and implantable recording device
… a body. This device can both record and trigger bioelectric events and may be chronically implanted in rodents as small as mice. This grants investigators the ability to continuously observe electrophysiological changes corresponding to disease progression in a single, freely behaving, untethered …

Nerve growth factor regulates Na+ transport in human airway epithelial cells
… curves were generated, but NGF only evoked bioelectric responses apically with the maximum response occurring at 1 ng/ml. To investigate the ionic basis for the bioelectric responses to NGF, responses to known ion transport inhibitors were generated in the absence or presence of 1 ng/ml NGF. …
