optogram

n. the physical image produced on the retina by the bleaching of rhodopsin by a visual stimulus (see pigment bleaching). In the 19th century, optograms were obtained by rapidly removing the retina of experimental animals after they had viewed a bright stationary stimulus and, in several instances, by examining the retinas of human prisoners immediately after execution.

Megan’s law

an amendment to the Jacob Wetterling Crimes Against Children and Sexually Violent Offender Registration Act requiring that state registries of convicted but released sex offenders be disseminated to the public so that communities will be notified of offenders’ presence in a particular neighborhood. More formally known as the Community Notification Act, it was initially passed in New Jersey in 1994 after a repeat sex offender murdered a 7-year-old girl named Megan Nicole Kanka; it became a federal law in 1996.
