The study assesses various behavioral tests and cell proliferation markers to evaluate the impact of these mutations and the potential for reversal through SSRI treatment. The goal is to analyze the data to draw conclusions about the roles of ber1 and ber2 in anxiety, depression, and cell proliferation, as well as the effectiveness of SSRIs in mitigating these effects."}
