Incubation in serotonin (10−9M for 6hr) produces an increase in the rate of cell proliferation in Cluster 10 in the in vivo (left pair of histograms) and eyestalk-ablated in vivo (right pair of histograms) preparations (n=8 for each group). Unlike the differential effects seen at higher levels of serotonin (Fig. 3), neurogenesis in Cluster 10 increased in both groups of animals relative to their respective controls. Statistical similarity is indicated by the same letters. ANOVA (F=25.5: p < 0.0001) followed by Tukey-Kramer HSD reveals pairs of means that are significantly different.
