Percentage of CA1 pyramidal cells in the right dorsal hippocampus containing inactive GSK3β.

<p>Double immunocytochemistry and the optical fractionator method were used to establish the pyramidal cell density in the CA1 and also the density of pyramidal cells containing inactive GSK3β. The absolute numbers of both densities were calculated and the percentage of all the CA1 pyramidal cells that contained inactive GSK3β was established. The data was analysed using a one-way ANOVA and Tukey’s post-hoc test. Aβ_25–35+FGL rats had a significantly higher percentage of pyramidal neurons in the CA1 that contained inactive GSK3β compared with Aβ_25–35 alone rats. (*<i>P</i><0.05). Mean ± SEM, n = 4.
