This paper describes a methodology to achieve a correct light radiation coloring for stimulating intrinsically photosensitive ganglion cells. Indeed, it has been shown that light is capable of causing a response from the master circadian pacemaker located in the suprachiasmatic nucleus of the hypothalamus. A study was conducted using a stereoscopic viewer capable of projecting specific wavelengths onto the corneas of patients. Patients were then monitored using Functional Magnetic Resonance Imaging, observing the response in subcortical (i.e., hypothalamus) and limbic areas (i.e., amygdala) and in some cortical areas primarily related to alertness. The spectral radiation emitted by the viewer was measured with laboratory instruments, and some considerations were also made on its possible influence at the level of the circadian cycle.

Abstract

This paper describes a methodology to achieve a correct light radiation coloring for stimulating intrinsically photosensitive ganglion cells. Indeed, it has been shown that light is capable of causing a response from the master circadian pacemaker located in the suprachiasmatic nucleus of the hypothalamus. A study was conducted using a stereoscopic viewer capable of projecting specific wavelengths onto the corneas of patients. Patients were then monitored using Functional Magnetic Resonance Imaging, observing the response in subcortical (i.e., hypothalamus) and limbic areas (i.e., amygdala) and in some cortical areas primarily related to alertness. The spectral radiation emitted by the viewer was measured with laboratory instruments, and some considerations were also made on its possible influence at the level of the circadian cycle.
