Lighting and Human Response in Motor Time, Autonomic Nervous System, and Emotion (LiHR)

May 5, 2017 updated by: Mahidol University

Lnfluence of Light Conditions on Brain Activity, Response Time, Autonomic Nervous Response, and Emotion in the Elderly and Young Adults

Light influences on human movement, autonomic nervous system, and emotion. It is inconclusive whether illuminance (Ev) and colour temperature (Tc) is appropriate to human movement, autonomic nervous systme, and emotion. Effect of Ev and Tc on responses of movement, autonomic nervous system, and emotion in human is investigated.
