Representative photograph (A) and schematic (a) Voronoi tessellation of the superior cervical ganglion neurons in different groups. b The distribution of the Voronoi polygon areas. c The CV of the spatial distribution of neurons in different groups: CV (coefficient of variation) of 33%–64% are with a random distribution (sleep-deprived group) and less than %33 has a regular pattern (other groups). d The mean of polygon areas for each neuron (µm2) in different groups. **** P < 0.0001 vs. the control;#### P < 0.0001 vs. the sleep-deprived group
