Figure 9 : Recuperation of paradoxical sleep after selective instrumental deprivation

Ordinate: Black columns: paradoxical sleep in % of total sleep. Hatched columns: slow sleep. Based on the first 6 h of recuperative sleep after deprivation. Abscissa: Duration of P.S. deprivation inh (up to 96) and days. Data obtained in 4 cats. Note the remarkable constancy of the relative proportion of P.S. (60%) following deprivation of over 72 h.
