Light-sensitive cells active in the retina even before the fetus can distinguish images may play a larger role in the developing eye and brain than previously thought. Intrinsically photosensitive retinal ganglion cells seemingly help establish blood supply to the retina, circadian rhythms and the pupillary light reflex. Researchers have now discovered that these cells are electrically connected in a network that is able to detect light intensity, suggesting a bigger role in development.

Do bad dreams serve a purpose? Researchers analyzed the dreams of people and identified which areas of the brain were activated when they experienced fear in their dreams. They found that once the individuals woke up, the brain areas responsible for controlling emotions responded to fear-inducing situations much more effectively. These results demonstrate that dreams help us react better to frightening situations, thereby paving the way for new dream-based therapeutic methods for combating anxiety.
