Summary
The paper investigates the impact of repeated short light exposures on sustained pupil responses during different cognitive tasks, and how this may be influenced by the intrinsic photoreception of intrinsically photosensitive retinal ganglion cells (ipRGCs).
Categories
Cognitive function and memory: The paper explores how light exposure impacts cognitive processes, specifically during tasks related to executive function, emotion, and attention.
Alertness and performance: The study discusses the role of light in stimulating alertness and cognition, and how this may be mediated by subcortical areas involved in alertness and sleep regulation.
Lighting Design Considerations: The research uses a specially designed, computer-controlled, MR-compatible light setup to administer light of varying irradiance levels and spectral compositions to participants during cognitive tasks.
Eye health: The study investigates the role of the pupil light reflex (PLR), driven by the combined contribution of rods, cones, and ipRGCs, in response to light exposure.
