Abstract
In the present work, sleep EEG of four healthy subjects was analyzed, containing a total of 3974 visually scored spindles. Frequency of each spindle was determinated with DFT and Matching Pursuit (MP) approaches. The estimated spindle frequencies were similar by the two approaches. Measures to quantify the dominance of spindle activity were developed. Results seem to indicate that there is one single dominant spindle activity component in about 90% of the spindles. In all these cases, it seems to be justified to use FFT and zero padding to resolve the spindle frequency more accurately than with no zero padding. In MP approach the frequency resolution can be selected freely.
