a polygraph measures physiological responses which are related to the EEG spike, but are a less direct measurement. As a result the polygraph is much easier to mess with by playing around with your physical state. For example you can confuse the polygraph by doing things like clenching your toes and fingers, as well as performing other jedi mind tricks.

They're not admissible as evidence in court (in the US, as far as I know).
sort of.
