Jag kom att tänka på detta under, som jag sparat i ett mail, jag har inte hunnit kolla upp om det är relaterat på något sätt:

A new Post "#1235: Another reason why not to use your cellphone next to yourhead" was written on the March 31, 2010 at 9:20 am on "EMFacts Consultancy".

Here's an important MIT study with implications for cell phone users who normally use their phone placed next to the right side of their heads (and possibly for Blue-Tooth headsets used on this side as well). If used on the right side it would place the antenna in close proximity to the right temporo-parietal junction which is located on the brain's surface above and behind the right ear. Considering that when the phone is used right next to the head over 40% of the energy can be absorbed by the brain, in some situations this could place the right temporo-parietal junction right in the firing line! Considering the obvious implications this certainly calls for further research. Too bad the industry basically controls research priorities.

It would be good to follow up this study with another that used an
operating cell phone next to the right side of the head to see if
there was a similar effect on moral judgment which would include risk taking behaviours.


Scientists discover moral compass in the brain which can be controlled by magnets

The moral compass, technically named the right temporo-parietal
junction, lies just behind the right ear in the brain

Scientists have discovered a real-life 'moral compass' in the brain
that controls how we judge other people's behaviour.

The region, which lies just behind the right ear, becomes more active
when we think about other people's misdemeanours or good works.

In an extraordinary experiment, researchers were able to use powerful
magnets to disrupt this area of the brain and make people temporarily
less moral.

The study highlights how our sense of right and wrong isn't just based
on upbringing, religion or philosophy - but by the biology of our

Dr Liane Young, who led the study, said: 'You think of morality as
being a really high-level behaviour. To be able to apply a magnetic
field to a specific brain region and change people's moral judgements
is really astonishing.'

The moral compass lies in a part of the brain called the right
temporo-parietal junction. It lies near the surface of the brain, just
behind the right ear.

The researchers at the Massachusetts Institute of Technology used a
non-invasive technique called transcranial magnetic stimulation to
disrupt the area of the brain.

The technique generates a magnetic field on a small part of the skull
which creates weak electric currents in the brain. These currents
interfere with nearby brain cells and prevent them from firing

In the first experiment, 12 volunteers were exposed to the magnetic
field for 25 minutes before they were given a series of 'moral maze'
style scenarios.

For each of the 192 scenarios, they were asked to make a judgement
about the character's actions on a scale of 1 for 'absolutely
forbidden' to 7 for 'absolutely permissible'.

In the second experiment, the magnetic field was applied to their
heads at the time they were asked to weigh up the behaviour of the
characters in the scenario.

In both experiments, the magnetic field made the volunteers less

One scenario described a man who let his girlfriend walk over a bridge
he knew was unsafe. The girl survived unharmed.

Under normal conditions, most people rate the man's behaviour as
unacceptable. But after getting the magnetic pulse, the volunteers
tended to see nothing wrong with his actions - and judged his
behaviour purely on whether his girlfriend survived.

Another scenario described two girls visiting a chemical plant where
one girl asks her friend to put sugar in her coffee.

The friend uses powder from a jar marked 'toxic' - but as the powder
turns out to be sugar, the girls if unharmed.

Volunteers with a disrupted moral compass tended to rate the girl's
behaviour as permissible because her friend was not injured - even
though she was aware the powder came from a jar labelled toxic.

Throughout the experiment, irresponsible or deliberate actions that
might have resulted in harm were seen as morally acceptable if the
story had a 'happy ending', they reported in the journal Proceedings
of the National Academy of Sciences.

It's not the first time that scientists have found parts of the brain
that specialise in ethics and morality. Last year American scientists
claimed to have found a "god spot" - a region of the brain that
controls religious belief.

TTScientists Tweak Subjects' Brains to Alter Their Moral Choices

Experiment helps show how and where these decisions are made

MONDAY, March 29 (HealthDay News) --- Changing someone's moral
response to a situation could be as easy as manipulating a piece of
their brain, a new study finds.

Previous research has shown that a brain region called the right
temporo-parietal junction (TPJ), located at the brain's surface above
and behind the right ear, is highly active when someone thinks about
another person's intentions, thoughts and beliefs.

In this new study, neuroscientists led by Rebecca Saxe of the
Massachusetts Institute of Technology disrupted activity in
volunteers' right TPJ by inducing a current in the brain using a
magnetic field applied to the scalp.

This impaired the participants' ability to make moral judgments that
require an understanding of other people's intentions. For example,
they were more likely to judge someone's failed attempt to harm
another as morally permissible.

Because transcranial magnetic stimulation interferes with the ability
to interpret others' intentions, a person must rely more on the
outcome of a situation to make a moral judgment, the researchers said.

The study, published in the March 29-April 2 issue of the Proceedings
of the National Academy of Sciences, offers "striking evidence" that
the right TPJ plays a critical role in making judgments, said lead
author Liane Young, a postdoctoral associate in MIT's department of
brain and cognitive sciences.

"You think of morality as being a really high-level behavior. To be
able to apply (a magnetic field) to a specific brain region and change
people's moral judgments is really astonishing," she said in an MIT
news release.

The study comes on the heels of similar MIT-based research published
last week in Neuron. In that study, Young and colleagues pinpointed
the brain's ventromedial cortex as a center for moral decision-making,
after studying nine patients with damage to that region.

(Bireal tipsade) Karl Kraus... visade på den ondska som låg inbakad i dessa till synes små fel. Han såg sina samtida medmänniskors vårdslösa behandling av språket som ett tecken på att de även var vårdslösa med behandlingen av världen som helhet.
