Document Summary

They live at the bottom of streams and lakes where it"s dark and murky, and they use the taste buds to detect prey and avoid predators. 15 feet away and detect amino acids at one part per 100 million: taste in mammals are generarally categorized into, salty: ionotropic, the detection of sodium ions entering through leaky. Consequently, the neurons would carry information for more than one taste modality: examined by observing taste sensilium in flies, the taste sensilium is also a touch receptor. An electrode is attached to the sensilium that can record responses to different taste stimuli. Mitral cells send signals further down the neural circuit: olfactory receptive cells have cilia that extend into the mucous membrane. The receptor proteins are one the surface of the cilia; they are g-protein coupled receptors. Activation of the receptors triggers the production of camp, which opens a na/ca channel. Na+/ca+ ions rush into the cell, depolarizing it.
