If this works, it lends credence to people that think cell and wifi frequencies are not neutral. The fundamental assumption behind neutrality is that the only effect on the human body is thermal.
- donquichotte 7y agoThis is different though. It looks like they are using transcranial stimulation, i.e. putting electrodes on both sides of your head and running a current through it, resulting in what I assume to be a quite homogeneous current distribution throughout brain tissue. RF waves' tissue penetration is stronger at the surface of a conductor, see Skin Effect. EDIT: substituting the frequency in [1], we arrive at ~9mm skin depth for 918MHz.
