Influencia de la prolactina sérica en la arquitectura del sueño.

The sleep is defined as a state of unconsciousness from which one can take out the person with sensory or other types of stimuli. The sleep and wake cycle, as many other physiological activities, have a circadian periodicity of approximately 24 hours. Different hormones have been studied to know their relationship with sleep. There are some reports of experimental studies in humans to determine the relationship between the physiological prolactin levels and sleep. The experiments in animals reports the relationship but with abnormal levels of prolactin. There is still a controversy regarding the relationship between the abnormally elevated levels of prolactin and the sleep architecture. [ABSTRACT FROM AUTHOR]
