Brain's Ability to Detect Magnetic Fields
Those of us researching the field of transcranial direct current stimulation (tDCS), have long been fascinated by the idea that the brain is an electromagnetic organ, and therefore should behave in certain ways that would be familiar to the field of study of general electricity and magnetism.
The nerve cells within the brain communicate with each other fundamentally with electrons and energy transport, albeit with a chemical foundation instead of direct and fixed conductors, such as cabling or etched metal lines.
Therefore it should also be little surprise that new research is finding out that the brain has a magnetic field detection ability as well, since the forces of electricity and magnetism are directly intertwined.
The calculation is quite simple: If the brain's very functional existence is based on moving electrons around, those moving electrons will then create magnetic fields, and then if those magnetic fields interact with existing external magnetic fields; voila, information is detected or transferred.
The fact that those subtle changes in electrical disturbances, and the subsequent magnetic fields, is detectable, on some level, shouldn't be that much of a surprise, since the fundamental relationship exists between the fields.
It's with this basic understanding, that the new reports of evidence of this relationship being verified to a certain degree, is thoroughly enjoyable and should add to the curiosity of the overall tDCS field.
