Melanopsin cell contributions to visual perception and decision making in humans

Summary

This thesis demonstrates that melanopsin-directed lighting enhances cone pathway contrast sensitivity and brightness perception, while also independently transmitting visual information and producing a characteristic biphasic pupil dilation during decision-making. These findings provide a scientific basis for designing energy-efficient lighting spectra that can modulate mood and cognition through targeted melanopsin pathway activation.

Key Findings

Melanopsin-directed lighting increases contrast sensitivity of the canonical cone pathway, enhancing brightness perception.
The melanopsin pathway transmits visual information independently of rod and cone mediated vision.
Melanopsin activation during decision making produces a signature biphasic pupil dilation response.
Outcomes support development of new energy-efficient lighting spectra targeting melanopsin-mediated effects on mood and cognition.
