In a separate experiment, researchers subjected the volunteers to sudden bursts of loud white noise to test their startle reflexes, measured by sensors attached to the muscle below the eye that recorded how hard people blinked...
...face of this challenge, Ivins' lawyer says, the FBI stalked his client in pursuit of evidence he didn't have, driving him to drink and to depression. Ivins took at least two polygraph tests, says his attorney Paul Kemp, and apparently passed both of them. "That certainly was our impression," he says. "That's certainly what he was told...
