Research ArticleOpen accessIn the abstractForensically Flies Detect the Nutritional Value of Corpses Through Neuro-Chemoreceptive Cells-(5th Cell)Hedayat Abdel Ghaffar, Tarek Tantawi, Ibrahim Gaboub et al.Animals have evolved several chemosensory systems for detecting potentially dangerous foods in the environment. Activation of specific sensory cells within these chemosensory systems usually elicits an aversive behavioral response, leading to avoidance of the noxious foods. Blowflies respond to sugars, salts and water through the activation of specific chemoreceptor neurons in the antennal, labellar and tarsal chemosensillae. These insects also … …Neuroscience International, Vol. 3, Issue 2 · 5 Sep 2012 · 7,243 accessesView PDF Cite
