Abstract When the neural systems which are responsible for postural atonia during paradoxical sleep are destroyed, sleeping cats periodically display stereotyped motor activity, revealing a rich repertoire of non-goal-directed ‘oneiric behaviour'. 
Sleep, Dreams, and States of Consciousness
An understanding of the brain basis of consciousness is one of the oldest dreams of neuroscientists and physicians. Although a knowledge of its subtleties is at a very early stage, we are now

Do REM (lucid) dreamed and executed actions share the same neural substrate
This paper addresses the correlation of dreamed and actual actions. This issue is related to the theory of neural simulation of action. The simulation theory postulates that, in general, covert
Do animals dream?
It is argued that parallels that exist between the phenomenology, physiology, and sleep behaviors during human dreaming provide an avenue to investigate dreaming in non-human animals.

The neural correlates of conscious experience: an experimental framework
It remains to be seen whether the neural signature of consciousness relates to the location of the neural activity, the temporal properties of the Neural Signature of consciousness or the form of the interaction between activity in different brain regions.

A re-evaluation of the effects of lesions of the pontine tegmentum and locus coeruleus on phenomena of paradoxical sleep in the cat.
The conclusion drawn from these experiments and from a review of the literature is that the hypotheses stating that the locus coeruleus or other isolated nuclei of the pons are specifically concerned with the initiation of paradoxical sleep are not clearly supported by available evidence.
Evidence for the presence of eye movement potentials during paradoxical sleep in cats.
Phasic activities related to eye movements in the dark in abducens nucleus (N.VI), lateral geniculate body (LGB), visual cortex, and lateral rectus muscle were analyzed in 18 cats with chronically implanted electrodes and the mechanisms responsible for EMP and PGO wave activities are discussed.
An inhibitory mechanism in the bulbar reticular formation.
In the experiments to be reported, this inhibitory influence has been demonstrated by observing the effect of bulbar stimulation upon reflexes, upon decerebrate rigidity and upon responses evoked from the motor cortex.
Étude des relations entre l'activitéponto-géniculo-occipitale (PGO) et la motricitéoculaire chez le chat sous réserpine
The latencies measured between the phasic events of the central visual and oculomotor systems permitted us to confirm the anatomical organisation involved between the pons and the NGL, and to formulate a hypothesis for the organisation of the pathways responsible for the phAsic events at the level of the VIth nucleus.
