As a receiver, the implant could send biological information about the abductees back to the Aliens. Much like the way satellites monitor Earth's weather changes, the implant could send continuous physiological information back to the Aliens. 3. As a tracking device, implants could serve as location markers for where abductees are located at any point in time. As conservationists and wildlife specialists follow herd migrations, so could Aliens follow migration patterns of abductees under their watchful eyes. Perhaps this is the reason.
Police departments use similar tracking devices known as tethers for certain criminal offenders.
The tethers transmit an electronic signal registering the person's location to the monitoring device. This could explain why some abductees hear their names called from inside their heads or hear other instructions or guidance information coming from inside their heads. The communication process could be subtle, such as to transmit any extreme emotion being experienced by the abductees. Whether danger or joy, the impact of the emotion could be communicated back through such a device. Many abductees believe there is a telepathic or mental link-up process that begins the day of an impending abduction.
