Sleeping flies that still manage to escape shed light on inhibitory neuronal networks

Flies too need their sleep. In order to be able to react to dangers, however, they must not completely phase out the environment. Researchers at Charité–Universitätsmedizin Berlin have now deciphered how the animal's brain produces this state. As they describe in the journal Nature, the fly brain filters out visual information rhythmically during sleep—so that strong visual stimuli can still wake the animal.
