Researchers at the University of Wisconsin-Madison recently conducted a study to determine if the effects of sleep and wake had any effect on calcium levels in the Kenyon cells of fruit fly brains, according to Medical Xpress.

The researchers were interested in studying the changes in neuron calcium levels, as measured by GCaMP5 fluorescence, while the fly was transitioning between periods of wake to sleep and back. They found that calcium levels in individual neurons increased when flies woke up and decreased when they fell asleep.
