Daniel Joyce, PhD, The non-image forming visual pathways in health and disease

The non-image forming (NIF) pathways are intimately entwined with human wellbeing. They project to over a dozen brain regions and modulate cognitive performance, mood, pupil kinetics, and sleep/wake behavior. In this talk, i discuss clinically relevant pupillometry methods to measure NIF function, including the normative limits of the pupil light reflex in health and their dysfunction in Parkinson's disease. I will also discuss the NIF pathways from a sleep/wake perspective: We have attempted to "hack" the human circadian system with sequences of millisecond light flashes and show that this system can be phase-shifted by extraordinarliy brief and dim light flashes. Modern lighting enables precise manipulations of the wavelengths, timings and intensities of light, and so there is enormous scope to optimize lighting environments not just for image forming vision, but for NIF vision that supports physiology and health too.
