We had an interesting discussion on sleep, where the context was fruit fly (Drosophila). what is sleep in fruit flies? How do we define sleep? Do microbes or rotifers sleep? Cubists also made one design to verify the hypothesis: fruit flies do sleep.
In fruit flies, sleep can be conveniently estimated by measuring the locomotor activity of the flies using techniques and instruments adapted from the field of circadian behavior.
To facilitate the genetic study of sleep, we documented that rest behavior in Drosophila
melanogaster is a sleep-like state. The animals choose a preferred location, become
immobile for periods of up to 157 min at a particular time in the circadian day, and are
In order to be considered sleep-like, an inactive state should have the following features (6, 16): (1) consolidated circadian periods of immobility, (2) a species-specific posture and/or resting place, (3) an increased arousal threshold (although the state can be reversed by intense stimulation), and (4) a homeostatic regulatory mechanism.Joan CHendricks1*Stefanie MFinn1Karen APanckeri1JessicaChavkin1Julie AWilliams1AmitaSehgal1Allan IPack1
Sleep is also present in invertebrates, and an extensive analysis in Drosophila melanogaster has shown that sleep in fruit flies shows most of the fundamental features that characterize sleep in mammals.Sleep and wakefulness in Drosophila melanogaster Sleep and wakefulness in Drosophila melanogaster - PubMed
Vinegar is acidic. Vinegar’s pH level varies based upon the type of vinegar it is. White distilled vinegar, the kind best suited for household cleaning, typically has a pH of around 2.5.pH of Vinegar: Acidity and Strength
