Description: Confocal image of a leg of a Drosophila Melanogaster. Sensory neurons at the base of the Mechanosensory Bristles (hairs covering the leg) are expressing GFP (green). These neurons are activated when the bristle is deflected, allowing the fly to sense external forces such as wind or contact with objects. Autofluorescence of the leg cuticle is shown in red.
