We all know that electromagnetic fields are magic
and can do anything at any time for any reason.
Sometimes, though, they can be harnessed to do
certain things in particular. Electromagnetic fields
can be applied to the skull, making your brain do
strange, and sometimes completely inexplicable
things. Find out how scientists use magnetic
fields to rip your mind apart, make it better, and
have it do tricks like a trained puppy.

10. Shred its DNA
Well, it's no surprise that not all the things a high
electromagnetic field can do are good. Actually,
even a mild electromagnetic field can wreck a
brain if it's applied over a long time. Scientists
found that an electromagnetic field applied to lab
rats over time resulted in broken strands of DNA
in the brain. Not just anywhere - the brain
specifically. It's possible that this DNA damage is
the cause of brain tumors, and the reason why
people don't just walk around with brain-boosting
electromagnetic hats all the time.

9. Stimulate its Growth
Oh, electromagnetism! It's such a trickster! One
moment its ripping through DNA strands like a pit
bull through an old sock, the next minute it's
tenderly nurturing the growth of neurons.
Scientists found that brains subjected to regular
transcranial electromagnetic stimulation for only
five days showed an increase in stem cells in the
hippocampus. This is the part of the brain that
governs memory, making electromagnetic
stimulation a possible treatment for Alzheimer's
and stroke patients.

8. Train you off food and water
Rats who had been deprived of water were placed
in a strong electromagnetic field and offered a
sweetened solution. Although they did drink, they
drank less than those given the solution without
exposure to the electromagnetic field. When rats
were given the solution and later exposed to the
field, they developed an aversion to the solution
over time. Enough electromagnetism may turn
you off your favorite food.

7. Make you spin in circles
Other rats (who have a terrible time of it during
experiments like these) were found to walk in
tight circles under the influence of an
electromagnetic field. Scientists think that the
field takes out the rats' sense of balance, making
them lurch in circles. The lack of balance also
may have induced nausea, which causes lethargy
and could be one of the reasons that rats go off
their feed.

6. Pacify you completely
Transcranial electromagnetic stimulation -
subjecting people to strong electromagnetic fields
aimed at specific parts of the brain - is sometimes
used as a treatment for bipolar disorder or clinical
depression. Some patients find an immense relief
in this. Other people, who don't suffer from
depression, have reason to worry about it. People
without any diagnosed medical illness while under
such stimulation can be relaxed to a state where
they can't think of anything, at all, that bothers
them. If that kind of relaxation can be induced at
will, it could be used to pacify large parts of the
population.

5. Alter your morality
All that relaxation has a price. Sometimes we're
meant to fret. For example, if someone is about to
cross a dangerous bridge, and we're aware of the
chance it can collapse, and they aren't. Those
without a magnetic field dancing around their
brain, think that allowing the person to cross the
bridge would be immoral. Those with a field gaily
capering through their neurons think that, as
long as this hypothetical person made it to the
other side in one piece, there's no real moral
problem. Judging the morality of a situation
strictly by the outcome makes any crimes with
'attempted' in their description no longer crimes
at all. It takes away a person's intentions and
bases morality entirely on what happens to occur.
Morality becomes a matter of chance.

4. Take out your power of speech but leave
your ability to sing
Broca's area in the brain controls the ability to
speak. A large electromagnetic field applied to the
area takes out that ability entirely. Subjects under
this kind of stimulation simply stop speaking the
moment the field disrupts that part of the brain,
while the rest of the functions are unimpeded.
One of those other functions is singing. Although
many people think that singing words and
speaking words are much the same function, the
ability to perform each action is housed in
completely different parts of the brain. So people
who are unable to talk will sing perfectly normally.

3. Induce panic, disorientation, and deep
fear
Although some kinds of electromagnetic fields,
applied to certain areas of the brain, pacify people
and put them in a good mood, others are said to
induce fear. Sometimes people report a
persistent, if mild, sense of unease. Others have a
more visceral response, feelings of despair and
paranoia, sliding into overwhelming terror.

2. Cause Seizures and Death
Under the worst circumstances, exposure to
electromagnetic fields can cause a number of
serious effects in the brain. Studies have shown
that it can change the flow of blood in the brain,
and turn off neuron groups. Some people, under
the influence of high magnetic fields have caused
people to have violent seizures, and even lose
consciousness, slip into comas, and die. This is
one of the reasons why houses under high
electromagnetic fields have ghost stories
associated with them. In conjunction with the
deep feelings of unease, mysterious seizures and
deaths start all kinds of rumors. Of course, those
rumors aren't as bad as . . .

1. Make you see ghosts
Electromagnetic fields, or electric shocks, have
induced specific hallucinations in people. Those
who are exposed to them, even in laboratory
settings, have caused people to complain about a
feeling of people following them, talking to them,
or watching them. This is not always an
uncomfortable sensation. Some people interpret
this presence as a malevolent presence, especially
if it's coupled with a feeling of unease, but others
say they felt an inspiring or comforting presence.
Ghost hunters will sometimes say the reverse -
that ghosts cause a high electromagnetic field, or
sometimes that a high electromagnetic field will
allow ghosts to appear. Nobody is sure, yet, what
these fields do to ghost brain DNA.
