title: [Effect of delta-sleep-inducing peptide and its analogs on the encephalogram of normal rabbits during sleep deprivation and on learning processes in the rat].
abstract: The delta-sleep-inducing peptide and its 10 analogues increased the total amount of slow oscillations in the rabbit EEG and shifted the spectrum towards the long-wave area. When comparing the EEGs of intact and sleep--deprived rats, the effect of delta-peptide was stronger in the latter animals. The learning of rats in U-shaped labyrinth before and after sleep deprivation suggested that delta-peptide improved the learning in sleep-deprived animals. Experiments with negative influences showed that the delta-peptide could be a protective anti-stress factor.
