complex behavioral sequence that allows it to arave at the source of the odorous plume. Studies on the effect of various neurotransmitters and neuromodulators have shown that odor perception and response periodicity is greatly influenced by several biogenic amines. Further studies on the effect of agonists (a chemical substance capable of combining with a nervous receptor and initiating a react...
