The Vision Laboratory at Northeastern University employs psychophysical and computational methods to better understand visual perception. Current topics under study include:
- chromatic detection and discrimination
- color appearance
- visual plasticity
- the relationship of response times to thresholds
A major thrust of our work has been to model the color mechanisms that underlie chromatic detection and discrimination. These mechanisms are relatively simple circuits that combine signals from the cone photoreceptors of the retina; the mechanism outputs are then sent to other brain centers for further processing before contributing to observable behavior (such as making detection responses).
