| Popis: | Chemoreception plays a central role in the survival and reproduction of many animals in aquatic environments. Fishes use three chemosensory systems, the olfactory system, the diffuse chemosensory system, and the taste (gustatory) system. While these are present in the sea lamprey, a majority of chemosensory research has focused on olfaction. This review summarizes current knowledge of the lamprey chemosensory systems, including stimuli, receptors, neural pathways and behavioural roles of the chemosensory stimuli. A description of the olfactory sensory neurons located deep within the nostril, of synaptic pathways within the brain and of modulatory mechanisms that underly the translation of olfaction to movement are included. The lamprey diffuse chemosensory system may enable solitary chemosensory cells on the skin of the mouth, nostril, gill, and tailfin to function as sentinels for rapid responses to chemical stimuli. While little is known abouth the lamprey taste system, taste buds are located within the pharynx, thus enabling chemosensory responses to material that has entered the body cavity. Knowledge and understanding of function of these three chemosensory systems supports the management of sea lamprey populations. |
