Researchers Find Key to Brain Optimization

Brain

New research has proven that electromagnetic stimulation can alter brain organization and make the brain work better.

In a study published in the Journal of Neuroscience, researchers from The University of Western Australia and the Université Pierre et Marie Curie in France have demonstrated that weak sequential electromagnetic pulses (repetitive transcranial magnetic stimulation -- or rTMS) on mice can shift abnormal neural connections to more normal locations.

UWA PhD candidate Kalina Makowiecki said that even low intensities of pulsed magnetic stimulation could reduce abnormal neural connections, shifting them towards the correct locations in the brain.

Makowiecki said that this reorganization can be associated to changes in a specific brain chemical and can occur in several brain regions.

She stressed that the structural reorganization can have minimal side effects in humans, because, structural reorganizations was not seen on the healthy brain of the mice they tested it on.

Researchers said that electromagnetic pulses like Transcranial magnetic stimulation (TMS) on mice shifted abnormal neural connections to normal locations.

TMS is a noninvasive method that can cause depolarization and hyperpolarization in the neurons of the brain.

The National Institute of Mental Health said that TMS uses a magnet instead of an electrical current to activate the brain.

This causes an electromagnetic coil to be held against the forehead and short electromagnetic pulses administered by a coil.

Electrical current that stimulate nerve cells caused by the magnetic pulse then targets the brain region.

They believe that this discovery can have important implications in treating many nervous system disorders related to abnormal brain organization like depression, epilepsy and tinnitus.

Makowiecki said that their findings can greatly increase the scientists understanding of the cellular and molecular events that occur in the brain.
