A look at new pushes to control brain neurons.
Scientists have been poking and prodding the brain for centuries in hopes of learning how this interconnected network influences thoughts, emotions, movement, mental and behavioural problems, and just about everything else that makes us human.
One of the great advances in neuroscience came in the 1930s, when a surgeon named Wilder Penfield used electrodes to explore the brains of epilepsy patients.
Stimulating different parts of the brain with electricity revealed which regions control what movements, allowing him to identify areas to avoid during surgery.
Penfield’s findings led to the first functional map of the motor areas of the brain.
Until recently, electrical stimulation remained the go-to method for studying the brains of experimental animals, revealing the actions controlled by different parts of the brain and their specialised neurons.
But the technique had serious drawbacks. Inserting electrodes into the brain can damage the cells under study and electrical stimulation was nonselective, so it was impossible to know what was being targeted.
In 1979, Francis Crick (who turned his attention from DNA to neuroscience) made a suggestion: Researchers hoping to decode the brain would need to manipulate one type of neuron without altering others.
Light, he surmised, could provide a precise, ‘non-destructive solution’.
Crick was on to something, but it would take decades for science to catch up.
Today, they are making serious progress in the field.
Developed in the early 2000s, optogenetics — the combined use of genetic and optical (light) methods to control genes and neurons — is among the most rapidly advancing technologies in neuroscience.
With precisely timed pulses of light aimed at targeted tissue regions or cells, optogenetics allows researchers to trigger or block events in specific cells of living animals.
Put simply, optogenetics is an “elegant” technique of controlling neurons in the brain using light.
Neurons are loaded with special light-sensitive proteins called opsins that sense light (in the visible range), convert it into electric signals, and activate neurons.
Conventionally, optical fibres connected to a light source are invasively implanted into the target tissue.
But reaching the deep areas of the brain using this technique is usually accompanied by extensive tissue damage, light toxicity, and harmful effects of thermal irradiation.
To ‘reduce’ this damage, scientists use microparticles that emit visible light in response to near-infrared irradiation (NIR).
These particles are injected into the target tissue and neuron activation is achieved without tissue damage.
In 2022, new studies have shown this method effective on mice, with scientists stating it is only a matter of time before this method can be ‘transferred’ to human use.
Multiple institutions have been competing to perfect this method in recent years.
Recently, researchers at Stanford and Singapore’s Nanyang Technological University (NTU) have developed a technique for controlling neurons from a distance, without invasive implants.
By injecting a molecule called TRPV1 — which helps us sense the heat in capsaicin chili peppers — into the brains of mice, they could control brain cells from up to one meter using infrared light beams:
U.S. researchers are also breaking similar grounds.
Mingzheng Wu, a graduate student at Northwestern University, plopped two male mice into a cage and watched as they explored their modest new digs: sniffing, digging, fighting a little.
During the experiment, published in Nature Neuroscience, Wu zapped the two mice at the same time and at the same rapid frequency — “putting that portion of their brains quite literally in sync”.
“The fact that you can implant these miniaturized bits of hardware and turn neurons on and off by light, it’s just mind-blowingly cool,” said Thalia Wheatley, a social neuroscientist at Dartmouth College.
The religious Cult of Scientism at it again finding more ways to control.
They have free range to chop, slice and examine as they please — and have for many decades.
Interestingly, controlling humans via sources of lights isn’t just restricted to this particular method.
In fact, this technique may be just the latest way they plan to control the species with lights.
We already understand the damage modern-day screen are causing us along the same lines.
LIGHTS AND THE NERVOUS SYSTEM
When I first heard of this field of optogenetics, it reminded me of a discovery I made a few years ago in relation to television/smartphone screens and manipulation of the human nervous system.
According to US Patent US6506148, methods have already been long-established to observe the physical and psychological effects of screen devices on the populous:
“Physiological effects have been observed in a human subject in response to stimulation of the skin with weak electromagnetic fields that are pulsed with certain frequencies near ½ Hz or 2.4 Hz, such as to excite a sensory resonance.
Many computer monitors and TV tubes, when displaying pulsed images, emit pulsed electromagnetic fields of sufficient amplitudes to cause such excitation. It is therefore possible to manipulate the nervous system of a subject by pulsing images displayed on a nearby monitor or set.
For the latter, the image pulsing may be embedded in the program material, or it may be overlaid by modulating a video stream, either as an RF signal or as a video signal. The image displayed on a computer monitor may be pulsed effectively by a simple computer program.
For certain monitors, pulsed electromagnetic fields capable of exciting sensory resonances in nearby subjects may be generated even as the displayed images are pulsed with subliminal intensity.”
Among a long list of other patents he has produced over the years, you will soon find items related to delivery technology and further means to use these devices on an unsuspecting public:
USP 6238333 – Remote magnetic manipulation of nervous systems.
USP 6091994 – Pulsative manipulation of nervous systems.
USP 5782874 – Method and apparatus for manipulating nervous system.
USP 5995954 – Method and apparatus for associative memory.
USP 6017302 – Subliminal acoustic manipulation of nervous system.
USP 5800481 – Thermal excitation of sensory resonances.
That’s right, light is already a strong controller of humanity.
The technological age has brought with it a zombified and dumbed-down pen to be herded.
Andrew Huxley, brother of Aldous Huxley, was an English physiologist and biophysicist who would win the 1963 Nobel Prize in Physiology or Medicine.
Huxley became famous for developing a set of differential equations that provided a mathematical explanation for nerve impulses, or the “action potential”.
This work provided the foundation for all of the current work on voltage-sensitive membrane channels, which are responsible for the functioning of the nervous systems.
All just a ‘coincidence’?
The lead protagonist Winston states in George Orwell’s Nineteen Eighty-Four that ‘the only free space is the few square inches inside of your head’.
The technocratic elite want to ensure not even that space is free.
