The Utah array has become a benchmark for multi-channel, high-density neural recordings and stimulation applications from large populations of neurons. Over the past two decades, this patented microelectrdoe array technology has undergone numerous refinements and repeated validations in a variety of species and preparations . This effort delivered a proven and well-documented method to obtain stable and long-term neural recordings of action potentials (spikes) and field potentials in brain and peripheral-nerve tissue.
