Patients with sleep apnea, a sleep disorder characterized by intermittent episodes of hypoxia (CIH), are at an increased risk for cardiovascular problems. CIH leads to a long lasting augmentation of respiratory and sympathetic motor output after the cessation of CIH, a phenomena termed long-term facilitation (LTF). LTF is a serotonin dependent mechanism. Additionally, serotonergic neurons in the raphe nuclei receive dense projections from orexin (OX) neurons; thus OX may contribute to the…

Without sleep, the body begins to weaken and experiences daytime sleepiness, fatigue, reduced alertness, and compromised performance in specific neurobehavioral domains. The severity of insufficient or disturbed sleep is usually a strong indicator of a sleep disorder, such…

When a person goes to sleep, the brain normally causes the muscles of the body to relax and stay still. However, sleep paralysis is caused when parts of the REM state of sleep intrude into wakefulness. Approximately twenty percent of the general population experience episodes of isolated sleep paralysis. People who experience sleep paralysis often wake up and develop anxiety when they become aware of the fact that they are incapable of moving their bodies and also unable to speak. Some people…
