One-minute stimulation with monochromatic light activates several visual and non-visual brain regions. The findings shed light on the impact of light stimulation on brain function.
each one of the brain connectivity pattern appears to be best arranged to perform better on tasks associated with specific cognitive domains: blue-light exposure activates areas associated with attention and circadian rhythm, green-light exposure improves visual attention and red-light exposure influences areas such as memory.
