Suppression of neurogenesis in the in vitro brain preparation as a result of adding sinus gland homogenate. In this assay, sinus gland homogenate was tested at three dilutions: 1:10, 1:20 and 1:40 v/v in incubation medium that contained serotonin (10−10M). Decreases in the rate of BrdU incorporation are roughly linear with the strength of sinus gland homogenate. ANOVA (F=24: p= < 0.0001) reveals significant differences that were confirmed by Tukey-Kramer HSD. Statistical similarity is indicated by the same letters. n=10 per group.
