A new study has come out that shows that by the second trimester of pregnancy, long before the baby's eyes can see images, they can detect light. The light-sensitive cells in the developing retina actually communicate with each other as part of an interconnected network. This gives the retina more light-sensititvty and enhances the influence of brain development. Only 3% of the cells that send messages through the optic nerve to the brain in the developing retina are sensitive to light. The other percenatge of cells in the developing retina communicate with other parts of the brain, such as the amygdala.
