New research sheds light on fly sleep circuit

In a novel study appearing this week in Neuron, Brandeis researchers identify for the first time a specific set of wake-promoting neurons in fruit flies that are analogous to cells in the much more complex sleep circuit in humans. The study demonstrates that in flies, as in mammals, the sleep circuit is intimately linked to the circadian clock and that the brain's strategies to govern sleep are evolutionarily ancient.
