Messing with our nervous system

The affects of “Nervous system manipulation by electromagnetic fields from monitors”

"Nervous system manipulation by electromagnetic fields from monitors" refers to a concept outlined in US Patent 6,506,148 B2. This patent suggests that it might be possible to influence a person's nervous system by emitting weak electromagnetic fields from a computer monitor or TV screen through subtle pulsing of the displayed images at specific low frequencies (around ½ Hz or 2.4 Hz are mentioned).
According to the patent, these pulsed electromagnetic fields could potentially excite sensory resonances in the skin of nearby individuals. The patent describes observed physiological effects in a human subject exposed to weak electromagnetic fields pulsed at these frequencies, including:
* Drowsiness
* Relaxation
* A feeling of pressure on the forehead
* Altered visual perception (seeing moving patterns with eyes closed)
* Emotional or physical sensations (tonic smile, tense stomach, sexual excitement, sudden loose stool)
The patent proposes that these sensory resonances in the skin could then affect brain activity, potentially leading to a "chemical detuning" effect. It also suggests that this image pulsing could be subliminal, meaning viewers might not consciously perceive it.
What it supposedly affects:
If this technology were viable and implemented, it could theoretically affect a range of physiological, emotional, and perceptual states in individuals exposed to the manipulated electromagnetic fields. The patent itself notes a variety of observed effects, suggesting a broad influence on the nervous system.
Important Considerations:
* Lack of Scientific Consensus: It is crucial to understand that the claims in this patent are not widely supported by the broader scientific community. While the patent exists, there is a lack of extensive, peer-reviewed research confirming these specific effects from monitor EMFs at typical exposure levels.
* Low EMF Levels of Modern Monitors: Modern LCD and LED monitors emit significantly lower electromagnetic fields than older CRT monitors. Regulatory standards are in place to ensure EMF emissions from electronic devices are within safe limits.
* Alternative Explanations: The effects described in the patent could potentially be attributed to other factors.
In conclusion, while the patent describes a method for potential nervous system manipulation via electromagnetic fields from monitors and outlines a range of possible effects, this remains a theoretical concept that lacks widespread scientific validation. The low EMF levels of modern monitors further complicate the feasibility of such manipulation under normal usage conditions.
