Professor Richard A. Normann, Emeritus Distinguished Professor of Bioengineering, Emeritus Professor of Ophthalmology & Visual Science.

Dr. Normann's team focuses on two basic electrode array architectures: the Utah Electrode Array (UEA) consisting of 100, 1.5 mm long silicon microneedles that project out from a 4 mm x 4 mm x 0.25 mm thick substrate and the Utah Slanted Electrode Array (USEA) which has a similar architecture but the lengths of the electrodes are graded from 0.5 mm to 1.5 mm.

The UEA was designed for cortical applications, and the USEA was designed for use in the peripheral nervous systems. They have used these interfaces to study parallel information processing by the central nervous system (visual and auditory cortex) and the control of muscle force and limb position by the peripheral nervous system.
