Transcranial Magnetic Stimulation
Claims have been made that magnets have healing effects on brain or psyche. Some refute it. Yet magnets can play am important role in brain processes.
Scientists with successful results have researched upon regrowth of new neurons in mice by using a magnetic stimulus in the memory region. This has to be performed on humans.
This technique can be useful in the treatment of Alzeimerâ€™s.Â It cam slow the progression of the disease, rather than cure it. Disorders such as depression, schizophrenia and rehabilitation after stroke can be treated by transcranial magnetic stimulation (TMS). A magnetic coil is used to introduce electrical fields in the brain, which activates or deactivates groups of neurons.
The TMS produces functional brain “lesions,” small regions of tissue that are temporarily paralyzed. Scientists are in a position to use lesions to locate many behaviors, feelings, sensations and mood centers. The technique will in due course help treat certain brain disorders. Researchers using the technique say that with repeated pulses of energy, the magnet literally jump-starts sluggish regions of the brain, much the way electroshock therapy does, restoring normal function for hours to weeks.
Magnet can affect mood in normal people. Repeated pulses, when delivered to an area above the left eyebrow, make people feel sad. Sometimes one feels apathetic and depleted of energy. But when an area above the right eyebrow was stimulated, many felt happier and more energetic. The effect did not last more than few hours.
TMS must be used carefully as it can induce brain seizures in healthy people. It is based upon the fact that neurons are essentially tiny electrical devices.Â Nerve cell when activated,Â passes a flow of electrons down its length. At the nerve end, the electrons induce the release of chemicals that pass to neighboring nerve cells. When stimulated, these cells generate an electric current and the process continues, sending coded messages throughout the brain.
