Physiological artifacts may include cardiac, pulse, respiratory, sweat, glossokinetic, eye movement (blink, lateral rectus spikes from lateral eye movement), and muscle and movement artifacts.

You may not actually reading the brain of the sender, but rather that the sender moves their eyes or their jaws or gets excited and increases their heart rate when transmitting the information.

That's why neuroscientists studying brain functionality put electrodes in rodents rather than put EEG devices on them. This gives them way higher-fidelity data.

The first step is making intracranial BCIs safe, the next step is to make them useful. They have much more promise than external BCIs, but until they're safe, people will continue to doubt them.
