Question

What exactly are “brainwaves” and do they work the same way as, say, radio waves?

In: Biology

Answer 1

When neuron fire, they generate electric signal, and when you THINK thats a whole lot of neurons generating a whole lot of signal, which produces a very weak electromagnetic radiation, the radiation is a wave like form that can be detected via sensors.

So yes, in a sense brain wave ARE radio waves, just very, very, very, weak.
