Item 3: Researchers find that the retina synchronizes the signals from different receptors before they get to the optic nerve to minimize temporal distortion. Segment #6. Skeptical Quote of the Week “I heartily beg that what I have here done may be read with candour; and that the defects in a subject so difficult be not so much reprehended as kindly supplied, and investigated by new endeavors of my readers.” Issac Newton Cambridge, Trinity College May 8, 1688
