(Medical Xpress)—A team of researchers in Belgium has found that people exposed to orange light exhibit greater brain activity than those exposed to blue light. In their paper published in Proceedings of the National Academy ...
In humans, a tiny area in the center of the retina called the fovea is critically important to viewing fine details. Densely packed with cone photoreceptor cells, it is used while reading, driving and gazing at objects of ...
