Today people are developing technology to interface directly with the brain. One of the more safe ones (besides just a keyboard and mouse) is EEG (ElectroEncephaloGram). With EEG electrical probes are attached to the head on the surface. These connections are wired to a pre-amplifier or instrument amplifier, digitized and feed into a PC or Mac computer for analysis.
Several very low frequency brain waves have been discovered. The waves are actually radio waves (electro-magnetic) but the magnetic component is so small that just the electrical component is picked up.
Look at this Ham Radio: receiver.
Consider a SDR (software designed radio) on this site, let your PC control the Radio parameters.
Consider GNU Radio as a great software option for Ham Radio.
Here is a great set of articles on the state of EEG BCI technology.
