Topographical distribution of spindles and K-complexes in normal subjects.

Author information

Laboratoire du sommeil, Hôpital du Sacré-Coeur de Montréal, Québec, Canada.


To assess the topographical distribution of sleep spindles and K-complexes, four 15-minute samples of stage 2 sleep in a group of eight healthy young adults were analyzed. Results show that a majority of spindles generated are detected over central regions, and that K-complexes are markedly predominant over prefrontal and frontal regions. These findings are consistent with the single-spindle generator hypothesis and raise questions concerning the Rechtschaffen and Kales rules for scoring K-complexes.
