Lab Rat? Who, Me?

Perhaps it was binaural in nature, with both frequencies above or below the normal hearing frequencies and created a heterodyne frequency resonant with certain parts of the brain, ear canal, or skull.

Sounds like a parametric array type of device. Two ultrasonic frequencies will mix in a nonlinear medium to generate sum and difference frequencies as well as other components. It's usually designed so that the difference of the frequencies will be audible.

"Two ultrasonic frequencies will mix in a nonlinear medium to generate sum and difference frequencies.."

This is the definition of heterodyne;the mixing of two signals to get a resultant sum or difference frequency.It is used in tuners today to shift variable frequencies into one IF frequency.(At least it used to be that way on the analog world).

This same methods could be used to generate a harmful frequency that is inaudible to the human ear.

As for remote control of animals, external devices have been used for years.Cockroaches had wires attached to their antennae to steer them.Obstacle avoidance was taken care of by the cockroach,the same with rat whiskers.This technology is wireless,which is a whole new ballgame.The current technology is large and bulky,but given time they will become very small and possibly microscopic in size,ideal for injection via syringe when you get you flu shot without your knowledge.

You are just jealous because the voices are not talking to you.

I don't mind hearing them,I just wish they would reach a consensus.

I have a mental construct of what I think might have happened in Cuba:

Take a crystal bowl,and find the resonant frequency.

Fill the bowl with Jello,let it set, and apply the frequency at a high amplitude.

The jello will begin to oscillate inside of the bowl.

Now,substitute a skull and a brain for the bowl and jello,and you have a possible scenario for damaging one's brain.

The resonant frequency could be the sum or total of two inaudible frequencies.

The victims reported hearing a bell like noise in certain spots in a room,but not in others.

Earplugs could not block it out.

The damaging frequencies could sweep a certain range of frequencies to achieve success.Say from 1500 to 3000 kz.

I know there are many variables,such as velocity of sound through body fluids and tissues,and bone conductance, variable skull sizes,etc.but the perpetrators probably did extensive homework on this method.

An infrared scan of the target could give a starting point for their frequency.

I'm just an old Rednek,and if I can think of the basic principle,there are much smarter men that can think of a way to perfect it.

When I was in college in the mid 90's I saw an ongoing experiment where they used rats to study addiction. The rats had wires connected to their heads through pink putty that I was told was dental cement. They could push a lever and receive a mild electrical signal to their pleasure center. Each time the level was pushed you would hear a click and it would increment a counter. The rat when released into the setup would explore the cage then press the level once then in another second or two press it again then in half that time again and after that press it as fast as they could till they were removed. They told me that the rats would press that level and ignore food and water until they perished if left unattended. In that study they were testing drugs to combat addiction where the stimulus was the ultimate addiction. This type of stimulation has been well known for a long time but is not exactly control any more than drug addiction is. I have also heard of experiments that enable directional control over an animal or person by way of impacting balance in the middle ear. The feeling is that you are falling one way and you correct by going the other way such that is is possible to use a remote to steer a person who looks like they are very off balance.

While both of these have been possible for a long time both are a long ways away from controlling someone's thoughts. People are more complex than rats and while we are subject to stimulus we also have more going on in our heads. Not that some nefarious use isn't possible as we better understand the brain and how it communicates but I would imagine their are easier ways to do things. The KISS principle still applies to super villains.

Too true we are nothing like rats. The average rat has a lifespan of 18 months. That alone should give us some idea of the immense differences in motivation and cognition that would have to exist even if capacity was equal.

The tools that exist are IMO less relevant to controlling someone's thoughts than they are as a means of criminal coercion, simply used as a weapon to obtain "control" or compliance by threat, violence, impairment etc. It is a fact that neural devices can be used to inflict pain, disability, choking,.... well, considering "Chinese water torture" was a classic, the devices all of which use pulse trains as a stimulus can simulate that with enough amplitude. That's not even to mention microdrug delivery systems which are part of the scene.

I think you have underestimated the appeal of inflicting physical abuse by remote, instead of choking and beating someone in person at the risk of being caught and arrested. Super villains aka organized crime of the 21st century are organ traffickers and human traffickers. According to police agencies, their use of surveillance and access to advanced technology and expertise is pretty standard. The fact they have medical partners is pretty much a given, since the organ traffic trade can't happen without them. It shouldn't be too hard to conceive how wireless bullying and beatings would dovetail with the existing opportunities.

I can't see them wiring up people's brains for mind control when television does a pretty good job now...

GA, you beat me to it.

You're about 60 years late, subliminal cues have been used in print, audio, and movies for at least that long. An early example of subliminal post-hypnotic control (aka brainwashing) is the central tool in the novel/movie "The Manchurian Candidate". Fast forward to Facebook and its use of child psychiatrists to capture the super-impressionable minds of little kids.

The reality is that we are used to picking up subtle clues from our surroundings. Things like body language, tone of voice, microfacial expressions, nervous tics, etc. have been used from the beginning of time, even animals exhibit dominant/submissive behaviors to other animals.

This example of a non-electronic remote control always brings a smile to the most stoic subject.
