" The recorder consisted of a biochip smaller than the head of a pin implanted into the hippocampus and nanosensors embedded throughout the body. Normally, the system lay dormant. But as soon as it detected severe deviations from the norm in various brain activity parameters - indicative of the stress caused by imminent death or great danger - the black-box would automatically contact the police and record the short-term memory in the hippocampus via molecular scanning. In the event of death, about one to two minutes of memories preceding the cessation of brain activity could be decrypted from the black box. "
