Reliable detection of sleep spindles from multichannel electroencephalogram (EEG) data has become an important issue recently. However, since the EEG data are usually accompanied with artifacts, pre-processing of these data has to be performed in order to increase detection accuracy. In this paper, we present the Discrete Wavelet Transform as an alternative method to capture the spindle activity. Wavelet Transform's advantage is its inherent way of decomposing the signal onto orthonormal dyadic frequency bands, thus excluding the need for notch or band pass filtering of the signal to eliminate electrical interferences. We display our results by the topographic map of the spindle activity.
