The volume of the hippocampus does not differ between wildtype, heterozygous and <i>Bmal1-</i>KO mice.

<p>A) Cavalieri estimates of total hippocampal volume in <i>Bmal1</i> (+/+), (+/−), and (−/−) mice at approximately 100 days of age. Estimates were calculated from the cresyl violet stained tissue series utilized in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0099527#pone-0099527-g003" target="_blank">Figure 3</a> for pyknotic cell counts. Hippocampal volume estimates were not significantly different across genotypes.
