Audio frequency headache is the term used to describe the sudden, violent, and often frightening experience that can result when the brain is overloaded with electrical impulses.
A recent survey of more than 5,000 people across the US revealed that a whopping 94 per cent of those who experienced it had not had a medical condition that causes it.
Researchers from the University of Utah in Salt Lake City have been researching this phenomenon for years, using brain scans to track how the brain responds to electromagnetic fields.
It has been found that when people are exposed to electromagnetic frequencies, they have more of a negative reaction to them than when they are in the presence of neutral or even positive electrical stimuli.
The reason is that when they experience a strong magnetic field, their brains become more receptive to the electrical impulses and are less sensitive to the presence or absence of other things.
Professor James Laughlin, who led the study, said this means they have a greater sensitivity to the electromagnetic fields and the more they feel their brain is being stimulated, the more likely they are to experience a sudden, traumatic event.
“It’s not just the intensity of the electromagnetic field, it’s the frequency of the field,” Professor Laughlin said.
This is the mechanism that we think triggers these events.
“We found that people who experienced frequency headache had a greater percentage of their brain responding to the same stimuli as those who were not experiencing it.”
Professor Laughlin and his team found that if they used a brain scan that included the brain’s electrical activity, they were able to pinpoint the specific location of the brain waves that triggered the symptoms.
He said that the brain had a unique way of registering and controlling electrical impulses, which allowed it to track the frequency at which electrical impulses were sent from one part of the body to another.
For this, Professor Laughns team trained a robot to track these electrical impulses in the brain, which was then used to determine whether people experienced the phenomenon.
When a person was exposed to an electromagnetic field the brain would respond to the frequency, and the intensity, of the stimulation, rather than the presence and absence of others.
What causes this?
Professor Laughnes team looked at the frequency response of a person’s brain when they were exposed to a single pulse of an electromagnetic pulse (electrostatic pulse), with or without a magnetic field.
They found that the people who had experienced frequency headaches reported the highest levels of brain activity when the electric field was high.
But when the electromagnetic pulse was low, the brain showed the same pattern of activity.
As the frequency increased, the participants brain responded more strongly to the electric stimuli.
This was a result of a mechanism called the gamma band effect, where the higher the frequency the higher that amplitude is.
After this, the researchers used MRI scans to identify areas of the brains activity that were correlated with electrical signals that were sent to the brain.
People with frequency headaches are known to have high levels of gamma band activity, which is a result not only of the electric fields but also of other biological signals that are sent in from the brain to the surrounding tissue.
At first, the findings may seem like a result that has nothing to do with frequency headache.
But when you take a closer look at the data it becomes clear that the participants’ brains respond to a particular electrical signal from their brain, not the other way around.
During this period of time, the people’s brain had been trained to recognise the presence, intensity and frequency of these signals, and then the activity in the areas of activity that responded to those signals.
These areas are called the brain cortex, which allows the brain and the body the ability to communicate and control electrical impulses with each other.
One of the key findings from this study was that the EEG, or electroencephalogram, that was recorded in people with frequency and non-frequency headache correlated with the EEG that was measured in people without any neurological conditions.
While the EEG is not the only signal that is sent into the brain when people experience frequency headaches, it is one of the most powerful.
Professor Laughes team said that in this case, people with brain activity that is low when they feel electromagnetic fields had less brain activity, but this was still linked to a specific electrical signal.
To make the connection, they looked at a brain region called the hippocampus, which lies just above the cerebral cortex.
By looking at the brain activity of people who were experiencing frequency headaches at this time, they found that there was a strong association between brain activity and EEG, but not the gamma frequency.
In other words, people who did not experience any brain activity at this moment in time also did not have any abnormal EEG activity.
Professor John Buehler, from the Department of Psychiatry at the University College London, said that this finding suggests that people with frequencies of different frequencies may have
