In 1985, a raid took place at a laboratory belonging to the University of California, Riverside (UCR) that resulted in the removal of a monkey by the Animal Liberation Front (ALF). This monkey, called Britches, was a stump-tailed macaque who was born into a breeding colony at UCR. He was removed from his mother at birth, had his eyelids sewn shut, and had an electronic sonar device attached to his head—a Trisensor Aid, an experimental version of a blind travel aid, the Sonicguide—as part of a three-year sensory-deprivation study involving 24 infant monkeys. The experiments were designed to study the behavioral and neural development of monkeys reared with a sensory substitution device.
