Suprachiasmatic nucleus VIPergic fibers show a circadian rhythm of expansion and retraction.

ABSTRACT: In animals, overt circadian rhythms of physiology and behavior are centrally regulated by a circadian clock located in specific brain regions. In the fruit fly Drosophila and in mammals, these clocks rely on single-cell oscillators, but critical for their function as central circadian pacemakers are network properties that change dynamically throughout the circadian cycle as well as in response to environmental stimuli.^1,2,3 In the fly, this plasticity involves circadian rhythms of expansion and retraction of clock neuron fibers.^{4,5,6,7,8,9,10,11,12}
