Abstract

Antidepressants have been found to cause dysregulation of the autonomic nervous system. The purpose of this research is to show the activation of the 5HT2A serotonergic neuroreceptor agonist as a substitute for everyday SSRIs to depression. Adult male and female zebrafish will be randomly selected and divided into two groups, control (n=10) and experimental (n=10). In both groups, anxiety will be induced by housing the subjects individually for the duration of the experiment, but the experimental group will be dosed with TCB-2 (5HT2A agonist, 100 microM). Subjects will receive 12 doses of TCB-2 over the time period of 6 days with behavior measures taken every other day. To assess anxiety swim behavior will be recorded in a novel tank (6in x 2in x 6in). Anxiety level will be measured using 3 methods: average velocity (pixels/ms), bottom dwelling (sec), and latency (sec) to the top of the tank. Comparisons will be made between control and experimental groups. Results are expected to show a decrease in average velocity, a decrease in bottom dwelling, and a decrease in latency to the top after treatment with TCB-2. The activation of the 5HT2A serotonergic neuroreceptor has potential to be utilized as a method to decrease anxiety symptoms without some of the potential side effects that are seen with typical SSRIs that are used to treat depression or anxiety.
