Seeing in a new light

Written by Healthy Living

Babies in the womb may see more than we know, according to scientists at the University of California at Berkeley. By the second trimester, long before a baby’s eyes can see images, they can detect light.

Light-sensitive cells in the retina may play a larger role in the developing eye and brain than previously thought. These cells were thought to be simple on-off switches, presumably setting up 24-hour, day-night rhythms for the baby. But scientists found that the cells actually talk to one another as part of a network that gives the retina more light sensitivity than once known, and that may enhance the influence of light on the baby’s behavior and brain development.
