TLDR
The existence is postulated of an independent dual control for sleep and wakefulness by the rostral brain and caudal brain-stem structures in decerebrate animals which showed no systematic relationship with the ECoG and behavioral manifestations of the ro stral cerveau isole.About:

Reticulo-cortical activity and behavior: A critique of the arousal theory and a new synthesis
TL;DR: The fact that patterns characteristic of sleep, arousal, and waking behavior continue in decorticate animals indicates that reticulo-cortical mechanisms are not essential for these aspects of behavior.

Sleep suppression after basal forebrain lesions in the cat.
Dennis McGinty,M.B. Sterman +1 more
TL;DR: The severity of sleep suppression was found to be related to the size and localization of lesions placed specifically within the preoptic area and not to transient disturbances in feeding and temperature regulation.
Journal ArticleDOI
Different behaviors during paradoxical sleep without atonia depend on pontine lesion site.
TL;DR: It is concluded that inhibitory systems were damaged by these lesions and that PS without atonia is not simply a state during which neural activity of normal PS can be expressed behaviorally.
Journal ArticleDOI
Behavioral functions of the reticular formation.
TL;DR: It is hypothesized that discharge in most RF cells is primarily related to the excitation of small groups of muscles, which can parsimoniously explain many previous observations on the behavioral correlates of these cells, and is consistent with anatomical, physiological and phylogenetic studies of the reticular formation.
Journal Article
A re-evaluation of the effects of lesions of the pontine tegmentum and locus coeruleus on phenomena of paradoxical sleep in the cat.
TL;DR: 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.

Cyclic variations in EEG during sleep and their relation to eye movements, body motility, and dreaming.
TL;DR: Records from a large number of nights in single individuals indicated that some could maintain a very striking regularity in their sleep pattern from night to night, and that body movement, after rising to a peak, dropped sharply at the onset of rapid eye movements and rebounded abruptly as the eye movements ceased.

A stereotaxic atlas of the cat brain
Ray S. Snider,William T. Niemer +1 more
TL;DR: There are excellent regional atlases for both the cat and the monkey, but these are the first to cover the brain stem and basal telenccphalon in such a complete fashion and should prove of particular value to people working in the caudal brain stem.

Pupil Size in Relation to Mental Activity during Simple Problem-Solving
Eckhard H. Hess,James M. Polt +1 more
TL;DR: Changes in pupil size during the solving of simple multiplication problems can be used as a direct measure of mental activity and shows that mental activity is closely correlated with problem difficulty, and that the size of the pupil increases with the difficulty of the problem.

The occurence of low voltage, fast, electroencephalogram patterns during behavioral sleep in the cat
TL;DR: All animals showed many periods of a low voltage, fast (activated) EEG in the face of continued behavioral sleep as indicated by absence of muscle potentials, relaxed posture, unresponsiveness, and elevated auditory threshold.
