Medical Stopping human's brain

  1. Apr 26, 2006 #1
    I'm wondering whether heavy electromagnetic stimulations of neurons can cause our brain to stop working at all, in sense that all the neurons stop receiving the messages from any other. Are there any known hypothesis how our brain could be possibly made during an evolution? And Does the brain, working upon the electric field connect us in some way into the deep roots of the universe?

    This is called transcranial magnetic stimulation, and I don't know if you can stop neurons from working, but intense magnetic fields have been walked about before. How much space is between an NMR magnet and navigable space?

    If you stop all neurons from signalling each other, you've just killed the person...lack of all neuronal activity would mean brain death.

    MRI imaging of the brain does not affect the brain's functionality. Magnetic Resonance Imaging uses powerful electric magnets to create images of the brain. To my knowledge, there haven't been any reported side-affects of MRI or FMRI (Functional Magnetic Resonance Imaging).

    Not to be confused with nuclear magnetic resonance magnetic field generation techniques. NMR magnets are the strongest on Earth produced so far, with the record right now being 4-5 Tesla. Wow. strong.

    Oh, MRI utilizes NMR.

    Actually labs get up to 40T+ sustained, and 850+ pulsed.
