Developmental Electroencephalogram of Non-REM Sleep in Beagle Dogs

Abstract

Cross-correlation and power spectral analyses along with visual analysis were applied to electroencephalograms recorded during the NREM sleep in a litter of 5 beagles in order to evaluate the changes due to aging, and to establish the age-matched reference data for the clinical application. Based upon results obtained, the developmental course of the NREM sleep during the 1st year of life could be divided into 4 stages; from 0 to 6 weeks, from 6 to 14 weeks, from 14 to 24 weeks and from 24 to 50 weeks of age.
