Depression is the leading cause of disability worldwide, and millions of people have something known as treatment resistant depression.
They have failed at least one oral antidepressant.
Others have depressive episodes and end up in emergency settings, where physicians have started to have success using large magnets known as trans cranial magnetic stimulation to pulse a person's brain, change their circuitry and in real time decrease these depressive episodes.
The reason this works is because our brain and nervous system is actually an electrical system.
Faraday's law states that if you pulse of magnet, you can generate a current in electrically conductive substances like the brain.
Since your hair and skull are not electrically conductive, this is why the magnet can get put on the outside your head and actually change.
The brain past the hair and skull.
New scientific breakthroughs in the technology make it so the magnets can target very specific regions of the brain in the brains of people Having a depressive episode.
The subgenual anterior cingulate is overactive and in another region known as the left dorsal lateral prefrontal cortex.
It is down regulated or has lower activity in people who are depressed.
