Microscope Art


This highly-detailed image of the central nervous system from a horned dung beetle (Onthophagus sagittarius) was captured with a laser-scanning confocal microscope. Imaged during the late pupa stage, this beetle was about to complete metamorphosis. The optic lobes (top) are in the process of growing and extending towards the outer surface of the head to form a pair of compound eyes. Different colored fluorescent labels were used to visualize the distribution of a structural protein (red), the neurotransmitter serotonin (green), and genetic material (blue).
