Anti-Depressive And Anti-Obesity Changes Following Either Dietary Isoflavone Treatment Or Injection Treatment With The Isoflavonoid Equol: Positive Response Dependent On Animal Age And Ovarian Status In Female Long Evans Rats, Crystal Blake
Theses and Dissertations
Two conditions associated with ovarian depletion are increased potential for depressive episodes and increased abdominal weight gain. In five different experiments we examined the effect of soy-containing diets or equol injections on depression, serotonin levels, weight gain (BW) and white adipose tissue (WAT) deposition of female Long-Evans rats in various stages of life. Rats were intact, ovariectomized or experienced natural ovarian failure (NOF). While this paper will present each experiment, only experiment 5 is outlined here due to space limitations. From conception the rats were exposed to either a soy-rich (Phyto-600) or low-soy diet (Phyto-low). Animals experienced NOF at approximately …
Dopamine Modulates The Lateral Giant Neuron And Serotonergic Facilitation In Crayfish, Joshua Scott Titlow
Dopamine Modulates The Lateral Giant Neuron And Serotonergic Facilitation In Crayfish, Joshua Scott Titlow
Theses, Dissertations and Capstones
The lateral giant (LG) neural circuit is a model system used to study the function of individual neurons. The LG circuit is part of a tail flip escape reflex that is a defensive behavior for crayfish. This thesis begins by addressing the effects of dopamine (DA), a neurotransmitter involved in normal and abnormal behaviors of most animals. Here it is shown that dopamine decreases the excitability of the LG neuron, a trigger for the escape reflex. An electrophysiology protocol was used to mimic sensory input to the LG neuron. Stimulating a sensory nerve in the last ganglion with an electrode …
