Serotonin And Its Effects On The Chronic Stress Response In Crayfish Following Nonylphenol Exposure, Tara M. Olen May 2023

Serotonin And Its Effects On The Chronic Stress Response In Crayfish Following Nonylphenol Exposure, Tara M. Olen

Masters Theses

Current research suggests that stress in both vertebrates and invertebrates is modulated in part by the neurotransmitter serotonin. It has been shown that crayfish can function as a good neurophysiological model, as they have less complex neurological systems than vertebrates, so mechanistic causes for stress can be more readily studied and understood. One potential stressor for aquatic species such as crayfish would be nonylphenol, a hydrophobic chemical used in agricultural products that can make its way into the water supply due to agricultural runoff. Nonylphenol can lead to physiological and behavioral impairments in crayfish and these impairments likely induce stress …
