# behav: the smart sleep of flies (Drosophila melanogaster)

<< Flies that cannot take to the air respond by sleeping more as they learn to adapt to their flightlessness, (..) The findings, (..) suggest that sleep may be an evolutionary tool that helps animals adapt to challenging new situations. >>

<< Fruit flies' sleep looks a lot like people's. Baby flies need a lot of sleep, but as they get older, their need for sleep diminishes. Flies become more alert with caffeine and drowsier with antihistamines. And if you keep a fly awake one day, it will sleep more the next. >>

# brain: lizard, an ancient dreamer (2)

<< Reptiles have a brain area previously suspected to play a role in mammalian higher cognitive processes, and establish its role in controlling brain dynamics in sleep. >>

<< The fact that we find a claustrum homolog in reptiles suggests that the claustrum is an ancient structure, likely present in the brains of the common vertebrate ancestor of reptiles and mammals, (..) While our results have not answered the question as to whether the claustrum plays a role in consciousness or higher cognitive functions, they indicate that it may play an important role in the control of brain states (such as in sleep), due to ascending input from the mid- and hindbrain, to its widespread projections to the forebrain and to its role in sharp-wave generation during slow-wave sleep, >> Gilles Laurent
