Magnets closer to the Head Can Make A moment Kidal

Brain activity can be influenced by the presence of strong magnetic fields. Even left-handed people can suddenly have a more dominant right hand, and vice versa although the effect is only momentary.

This is evidenced in an experiment at the University of California. Quoted from Dailymail, Wednesday (29/9/2010), which used the same type of magnet such as those used in transcranial magnetic stimulation therapy.

The device is placed on the left and right posterior parietal cortex, the brain associated with planning and 3-dimensional perception. The magnetic field is created when the tool is turned on, then disappear when turned off.

When the magnetic field on the left is activated, it turns out more volunteers using the left hand to perform minor activities such as holding the key and opened the door. Likewise, when reversed, the brain tends to choose the body part on the same side with magnets that are on.

However, these effects are not permanent, because when the magnet is turned off the volunteers directly back to the initial orientation. Therefore, the effect does not necessarily change the orientation to a more dominant part of the body.

"When about to press the elevator button, opening the door or take his key, the brain first decide which hand to use. The selection process that can be manipulated with magnetic fields, "says Dr. Flavio Oliveira, who led the experiment trsebut.

Magnetic field effects on brain activity not only revealed this time. Earlier this year, a study proves that the magnetic field can affect the perception of the good-bad, so-called effect of 'moral compass'.
