title: The modified Color Density Spectral Array--an alternative method for sleep presentation.
abstract: The modified Color Density Spectral Array (CDSA) method used for graphical representation of sleep patterns is described in this article. CDSA was presented for the first time in 1987 by M. Salinsky and coauthors. This method was adapted to display frequency course and voltage of EEG signal during sleep. The overnight sleep records of 35 healthy volunteers of both sexes (23 women, 12 men; aged 19-26) were analyzed in order to verify the modification of CDSA method. We propose to use combining the hypnogram and CDSA method significantly increases the informative value of data and results in enhanced quality of sleep analysis.
