Fourier Transform of EEG

For an attempt to explaining what the Fourier transform is or how something looks in the frequency domain rather than in time domain please refer to the following euroelectron post.


Has this been done on EEGs?


Would it be useful?


How would the signal of an EEG sound like if we speed it up in time domain so that we can hear the low REM frequencies? This may be done by recording and then increasing the playback sampling rate.
