Large-amplitude waves recorded in the pontine tegmentum, lateral geniculate body and visual cortex herald the onset and continue throughout paradoxical sleep. The role of these ponto-geniculo-occipital (PGO) waves, or spikes, has puzzled researchers since their discovery. This paper reports experiments in cats which have demonstrated that PGO spikes are essentially an epiphenomenon, an electrical sign of the activation of a "startle network" by the neural turmoil of paradoxical sleep.
