A Bird’S-Eye View On The Function Of Sleep, Charles Amlaner, Niels Rattenborg Dec 2009

A Bird’S-Eye View On The Function Of Sleep, Charles Amlaner, Niels Rattenborg

Charles J. Amlaner

Sleep has been detected in every animal that has been adequately studied (Cirelli & Tononi, 2008). The ubiquitous nature of sleep suggests that it evolved early in the course of evolution and therefore may serve a conserved function essential to all animals. This hypothesis forms the rationale behind the development of “simple” animal models of sleep (Allada & Siegel, 2008; Mignot, 2008). By studying sleep in animals such as the fruit fly (Drosophila melanogaster), where the power of genetic techniques can be readily employed,we may gain insight into the initial (perhaps cellular) function of sleep, a function that may still be relevant to understanding sleep in humans. Indeed, recent studies have already demonstrated remarkable similarities between sleep in Drosophila and sleep in mammals (Hendricks, Finn, Panckeri, et al., 2000; Shaw, Cirelli, Greenspan, et al., 2000; reviewed in Cirelli & Bushey, 2008). Although the utility of studying sleep in“simple”animal models is undeniable, it is unlikely that this approach alone will tell the whole story, especially given that Drosophilado not exhibit brain states comparable to mammalian slow-wave sleep (SWS) and rapid eye-movement (REM) sleep (Cirelli, 2006; Cirelli & Bushey, 2008; Hendricks & Sehgal, 2004; Nitz, van Swinderen, Tononi, et al ...

A module to help students to understand the nature and function of sleep and its effects on human health; to experience the process of scientific inquiry; and to recognize the role of science in society and the relationship of basic science and human health.


Thermoregulation And Sleep: Effects Of Thermal Stress On Sleep Patterns Of Glaucous-Winged Gulls (Larus Glaucescens), Mark Opp, Nigel Ball, Don Miller, Charles Amlaner Jul 1987

Thermoregulation And Sleep: Effects Of Thermal Stress On Sleep Patterns Of Glaucous-Winged Gulls (Larus Glaucescens), Mark Opp, Nigel Ball, Don Miller, Charles Amlaner

1. To determine effects of thermal stress on avian sleep patterns, incubating Glaucous-winged gulls were subjected to conditions of heat loss and heat gain via conduction from hollow copper eggs.

2. Heated manipulations resulted in significant reductions in sleep and rest relative to controls, whereas cooled manipulations had little effect.

3. The resilience of sleep to thermal stress is greater than that of rest. We suggest that the incompatability of sleep with conductive processes to off-load heat from the eggs is responsible in this case.

4. Pant Sleep, the behaviour in which birds appear to maintain some the benefits of ...
