Neurogenesis occurs 24 to 72 hours post fertilization in zebrafish. This is when neural stem cells differentiate to form neurons. The zebrafish that we are using in our experiment are 7 days post fertilization. Before conducting the first experiment, we hypothesized that we should see an increase in neural stem cell differentiation in T4 treated zebrafish due to an upregulation of her2. Since this study shows that her2 is not affected by Notch signaling after neurogenesis, it makes sense as to why not just one group, but most of the class saw a decrease in neural stem cell differentiation in T4 treated zebrafish.
