• Sleep deprivation elevates plasma corticosterone levels in neonatal rats.
• Plasma corticosterone (CORT) levels were measured after short periods of sleep deprivation in rats at postnatal days 12, 16, 20, and 24. There was an age-dependent increase in basal CORT levels and sleep deprivation significantly elevated CORT at all ages compared to non-sleep deprived controls. The levels of CORT after sleep deprivation in P16, P20 and P24 animals were similar, resulting in an age-dependent decrease of the magnitude of the response. Sleep deprived P12 animals had lower levels of CORT. However, the observed response to sleep deprivation suggests that sleep loss is a significant stressor at this age. These observations suggest that younger animals are more sensitive to the effects of mild sleep deprivation than older ones.

• Total sleep deprivation and the thyroid axis: effects of sleep and waking activity.
• Background: Circadian and sleep components modulate anterior pituitary release of thyrotropin (TSH), the chemical substance regulating the thyroid hormones, thyroxine (T), and trilodothyronine (T). The present study examined TSH, T4, and T3 concentrations across the wake-sleep boundary time (2300 - 0130 hours) before, during and after a 64-h sleep deprivation paradigm. ... Assessing the combined effects of activity and sleep deprivation on thyroid hormone economy is relevant to the relationship of high physical and/or cognitive performance demands during sleep deprivation inherent in extended military operations and space exploration. Method: There were 12 healthy subjects who were monitored during a 2-d baseline period, 3-d of total sleep deprivation and 2 nights of recovery sleep. ... Results: Change scores evaluated at the wake-sleep boundary time demonstrated significant inhibitory effects of sleep on thyroid hormone measures. As expected, sleep deprivation was associated with elevated TSH. However, sleep deprivation also significantly increased circulating levels of T3 at 2300 hours and T4 concentration change scores (2300 - 0130 hours). ... Physical activity remained constant while subjective ratings of effort to perform cognitive tasks increased significantly during sleep deprivation. Conclusion: Compared to sleep deprivation studies under constant conditions reporting no change in peripheral T4 and T3 levels, the present study suggests activity level, including cognitive effort to perform, during total sleep deprivation may produce substantive changes in the thyroid axis. ...

• Chronic sleep deprivation and lack of performance.
• com, 14 March 2003; Sleep 2003; 26(2): 117-26.
• Reducing sleep by only a couple of hours a night can have profound effects on cognitive performance. Although people deprived of sleep may only feel slightly sleepy, they appear to be unaware of how impaired their performance really is.
• Dangers of sleep deprivation.
• A study led by Dr Hans Van Dongen from the University of Pennsylvania School of Medicine in the USA, showed that people whose sleep was restricted to only 4 or 6 hours a night had significant, dose-dependent deficits in cognitive function. These deficits were similar to those seen in people who went without sleep for 3 days in a row. According to co-author Dr David Dinges, "This is the first systematic study to look at the prolonged cognitive effects of chronic sleep restriction lasting for more than a week. ... "Reduced cognitive abilities can occur even with a moderate reduction in sleep," said Dr Dinges.
• Some of the deficits in cognitive performance seen in people deprived of sleep on a long-term basis include, a reduced ability to:.
• Sleep deprivation over 14 nights resulted in an acute response in physiological variables measured polygraphically during sleep, and in nonrapid eye movement (REM) sleep, quantified as EEG power in the delta range, which measures the homeostatic regulation of sleep after a period of enforced wakefulness (sleep deprivation). Compared with people who were chronically deprived of sleep, those totally deprived of sleep showed extraordinarily large waking neurobehavioral functions and sleep delta-power responses, relative to the amount of sleep lost. Irrespective of the mode of sleep deprivation, lapses in alertness were nearly linearly associated with the summed time of wakefulness that exceeded 15. ... 16 hours of sleep during a 24-hour period to prevent neurobehavioral deficits becoming progressively worse.
• People who were deprived of sleep reported feeling only slightly sleepy and yet were unaware of the changes in their cognitive performance. "These findings show that while young adults may believe they can adapt to less than a full night's sleep over time, chronic sleep deprivation may seriously affect their performance while they are awake, and they may not even realize it," said Dr Patricia Grady, Director of the National Institute of Nursing Research, USA.

• Altered brain response to verbal learning following sleep deprivation.
• The effects of sleep deprivation on the neural substrates of cognition are poorly understood. Here we used functional magnetic resonance imaging to measure the effects of 35 hours of sleep deprivation on cerebral activation during verbal learning in normal young volunteers. On the basis of a previous hypothesis, we predicted that the prefrontal cortex (PFC) would be less responsive to cognitive demands following sleep deprivation. Contrary to our expectations, however, the PFC was more responsive after one night of sleep deprivation than after normal sleep. Increased subjective sleepiness in sleep-deprived subjects correlated significantly with activation of the PFC. The temporal lobe was activated after normal sleep but not after sleep deprivation; in contrast, the parietal lobes were not activated after normal sleep but were activated after sleep deprivation. Although sleep deprivation significantly impaired free recall compared with the rested state, better free recall in sleep-deprived subjects was associated with greater parietal lobe activation. These findings show that there are dynamic, compensatory changes in cerebral activation during verbal learning after sleep deprivation and implicate the PFC and parietal lobes in this compensation.

• A century ago, when people went to bed and awoke based on the sun's schedule, the average person could expect to get approximately nine hours of sleep a night. ...
• Chronic sleep deprivation (going for extended periods of time with less sleep than your body needs — which for some could be as much as ten hours a night) can cause a variety of physical and psychological problems. At its most basic level, loss of sleep can make people more irritable, less efficient and able to recall events, and more accident-prone. Research on the physical effects of chronic sleep deprivation suggest more serious and significant long-term complications, including: .
• Research from the University of Chicago Medical Center has shown that sleep deprivation interferes with the body's ability to regulate insulin production and sugar metabolism, potentially increasing the risk of diabetes.
• People who don't get enough sleep have been found to have changes in their immune response and white blood cell production, which can lead to difficulty in fighting off infections.
• It is believed that adequate amounts of sleep are essential for storing and maintaining long-term memories. People who are sleep deprived also score less well on cognitive tasks, such as judgment and reaction time. The National Sleep Foundation estimates that as many as 100,000 car accidents a year may be caused by sleep deprivation.

• As expected, the volunteers could not recall as many words when sleep-deprived as they could after a good night's rest. Because the prefrontal cortex is very active when people are awake and it is used during complex cognitive tasks, researchers expected to see reduced activity in this brain region after sleep deprivation. However, brain scans revealed quite the opposite: activity in the prefrontal cortex was greater after 35 hours of sleep deprivation compared with the activity after a good night's rest. Also to their surprise, researchers found that areas of the parietal lobes that were not activated after a normal night's sleep were activated in sleep deprived people. ...
• The researchers think that the prefrontal cortex may increase its activity after sleep deprivation because it is responding to some signal that is telling this brain region to "go to sleep.
