The electroencephalogram (EEG) together with electromyogram (EMG) of the ischiocavernosus, bulbocavernosus and levator penis muscles were chronically monitored across behavioral states of the armadillo Chaetophractus villosus. This animal has a very long penis, which exhibits remarkable phenomena during wakefulness (W), slow wave sleep (SWS) and paradoxical sleep (PS). During W it remains retracted within a skin receptacle. During SWS penile protrusion can be observed together with very complex… 
Impotence and Erectile Problems in Sleep Medicine
TLDR
The history of SRE testing from its discovery to its clinical role in evaluating male erectile dysfunction is reviewed and the discovery of an animal model to elucidate some of the basic neural mechanisms of S REs is presented.
Sleep-related nocturnal erections and erections during midazolam-induced sedation in healthy young men
TLDR
The findings suggest that erection monitoring during midazolam-induced sedation after nocturnal sleep deprivation after NSD may be convenient, however, validation of midazoledine-induced morning penile tumescence monitoring with a large population is mandatory.
Sleep Related Erections Throughout the Ages
TLDR
Throughout the ages, philosophers, theologians, physicians, members of ecclesial law courts, psychoanalysts, psychiatrists, sexologists, physiologists, and urologists have shown interest in SREs.
Characteristics of REM and NREM Sleep

TLDR
The fact that NREM appears to be associated with the gradual deactivation of a select group of brain structures that are then reactivated during REM suggests that the two sleep states either work in harmony with one another to maintain optimal brain function or that N REM undoes something that REM instantiates.
Spontaneous nocturnal erections and masturbation in captive male chimpanzees (Pan troglodytes)
TLDR
The findings support hypothetical functional explanations such as the facilitation of nocturnal emissions in order to increase ejaculate quality or an increase in tissue oxygenation to prevent erectile dysfunction.
Evolution of Psychoanalytic Interactions and Conflicts in Vertebrates
In this article, it is attempted to extend the Freudian psychoanalysis as the interactions and conflicts of the realities or memories with the instinctual drives to the vertebra subphylum in ecology
Unearthing the Phylogenetic Roots of Sleep
Ecology and neurophysiology of sleep in two wild sloth species.
TLDR
In sloths sleeping in the wild, predation pressure influenced the timing of sleep, but not the amount of time spent asleep, and the preference for sleeping at night in mainland sloths may be a strategy to avoid detection by nocturnal cats.

Experimental evidence of penile erections during paradoxical sleep in the rat.
TLDR
It is demonstrated for the first time that rats exhibit penile erections during paradoxical sleep (PS), and this method of chronic penile erection monitoring in the rat provides a new animal model for investigating neural mechanisms of sleep-related erections.

Two main different profiles of thermal behaviour in the armadillo Chaetophractus villosus are found, namely: a) one with high variation, mainly due to the daily cycle and the other with middle or low variation, with no predominance of thedaily cycle.
