WebIt is possible that experiences could be a ‘metallic’ or acidic taste in the mouth, magneto-phosphenes (sensation of a flash of light) and a perception of motion un-related to actual movement. The first two of these (taste and phosphenes) are related to small induced electric currents in the head, which have, in-turn, been caused by a changing magnetic flux. edgewater comcast https://isabellamaxwell.com

• Research has looked into visual prosthesis for the blind, which involves use of arrays of electrodes implanted in the skull over the occipital lobe to produce phosphenes. There have been long term implants of this type. Risks such as infections and seizures, have been an impediment to their development. • A possible use of phosphenes as part of a brain to brain communication system has been reported.
