Transcranial magnetic stimulation

Category: Actions

Type

Voluntary

Introduction and description

If you selectively target parts of the brain with a magnetic field it induces an electric current in our nerves and thus stimulates whatever function that part of the brain controls.  The Transcranial magnetic stimulator is a device that is designed to do just this.  Thus a TMS is a transducer of magnetic fields that stimulates the brain.

  

Method

There is not one device, but a number of devices that come within this category of the TMS, here are some examples:

  • Medical TMSs - which range from effective to downright dangerous in those who clearly do not understand the underlying principles on which this works.  It is noticeable that the manufacturers have been all too ready to capitalise on the idea, but none too ready to understand why and how it works.  There have been cases of induced epileptic fits, burns and psychosis from mal-administration of these devices

If we compare these devices with those which stimulate the brain electrically, they are far less intrusive.  The use of magnets rather than a direct electric current to the brain reduces the discomfort of the procedure.

    

But, you must be extremely careful which piece of apparatus you use

Dr Persinger’s carefully designed apparatus is by far the most effective and safe, from the point of view of the science and understanding behind its design, but is let down by being so amateurish in its construction, a sort of  Heath Robinson affair of makeshift bits and pieces.
In contrast the scientific equipment has been properly manufactured and made, but seems to lack all the understanding behind the original Persinger/Koren prototype. 

Repeatedly when examining all the solutions which come from the medical profession, I wondered why they always feel that when people are ill they need the equivalent of huge doses of anything whether it is electricity, magnetic fields, or medicines. 

Homeopathy, which has been proven to be effective, uses tiny doses.  Why can’t we learn from this that the body is a truly delicate and highly balanced machine which works off negligible doses of anything and can be repaired using only the tiniest amounts to get it back into balance.

I despair!!

   

How it works

see Stimulation via Resonance

Please go to this section for the full explanation.

Advantages

  • It works very effectively and it is, if operated at low intensity by people who really know what they are doing, safe.
  •  It is legal.

Disadvantages

  • This is not a cheap option, the equipment is expensive and only likely to be available via university labs or medically.
  • This mechanism is so targeted that it is clear people undergoing this would be as highly suggestive as they are during hypnosis.  But this is a technique that is really only viable with outside help, so however effective it may be you run the risk of being brain washed if your helper is of an unscrupulous disposition.  And of course, how can you tell?  In any form of medical or laboratory setting you may never have met the person doing the experiments or the nurse assigned to you and the assurances of those working with them is of no help because in the end they may have been brain washed too!!

    So we have here a potentially hugely effective, safe targeted mechanism, made almost unusable by the fact it needs to be operated by strangers to you.
