Posted by in category: biotech/medical

From changes in daylight across seasons to the artificial lighting choices in workplaces, it’s clear that the quantity and quality of light that a person encounters can significantly impact mood.

Now, scientists at Brown University think they know why.

In a new study published in the Proceedings of the National Academy of Science, the research team used functional MRI to reveal how signals reach the , and how brain structures involved in mood process those signals. The study demonstrated that some regions of the cerebral cortex involved in cognitive processing and mood show sensitivity for intensity.
