Researchers in the Center for Visual Science (CVS) have been at the forefront in developing advanced scientific techniques, including:
- Multi-electrode recordings in awake-behaving monkeys
- Virtual reality tools for studying complex visuomotor behaviors
- Advanced mathematical analysis of behavioral and neural data
- Adaptive optics applications to basic and clinical vision research
- Optical and molecular tools for refractive error correction and vision restoration
CVS had been built on the conviction that progress in vision science requires the coordinated efforts of scientists with very different skills. Researchers in the center apply a number of approaches to their research.
