...Wesley I. Payette; Brett L. Hodinka; Keelee B. Pullum; Melanie M. Richter; Noah T. Ashley ABSTRACT Sleep loss impairs cognitive function, immunological responses and general well-being in humans. However, sleep requirements in mammals and birds vary dramatically. In circumpolar regions...

... different sleep stages. Respiratory phenotype of male orexin knockout (KO-ORX, N =9) and wild-type (WT, N =8) mice was studied at thermoneutrality ( T a =30°C) or during mild cold exposure ( T a =20°C) inside a whole-body plethysmography chamber. The states of wakefulness (W), non-rapid eye movement sleep...

... reduced night-time sleep and greater sleep fragmentation. ACER may thus be part of a signalling system linking metabolism with sleep. To further understand the role of ACER in response to diet, we measured sleep and other nutrient-responsive phenotypes in Acer null flies under different dietary conditions...

...Leonie Kirszenblat; Deniz Ertekin; Joseph Goodsell; Yanqiong Zhou; Paul J. Shaw; Bruno van Swinderen ABSTRACT Although sleep deprivation is known to impair attention in humans and other mammals, the underlying reasons are not well understood, and whether similar effects are present in non-mammalian...

..., suggesting that some mechanisms protect brain tissue during periods of nutritional deficit ( de Souza et al., 2012 ). The influence of nutrition in early life on memory performance as adults might be mediated by differences in memory consolidation. There is accumulating evidence that sleep can improve...

...James Jaggard; Beatriz G. Robinson; Bethany A. Stahl; Ian Oh; Pavel Masek; Masato Yoshizawa; Alex C. Keene ABSTRACT Sleep is an essential behavior exhibited by nearly all animals, and disruption of this process is associated with an array of physiological and behavioral deficits. Sleep is defined...

Both males and virgin females kept on a 12 h light:12 h dark (12LD) cycle and constant temperature displayed night-time inactivity (sleep) followed by weak activity in the morning, an afternoon...

...Lisa Beyaert; Uwe Greggers; Randolf Menzel SUMMARY Sleep is known to support memory consolidation in animals, including humans. Here we ask whether consolidation of novel navigation memory in honeybees depends on sleep. Foragers were exposed to a forced navigation task in which they learned to home...

...Richard Stephenson; Vern Lewis SUMMARY The objective of this study was to determine whether the great pond snail, Lymnaea stagnalis , expresses a sleep-like behavioural state. We found that snails spontaneously enter a relatively brief (22±1 min) quiescent state characterized by postural relaxation...
