2.8. Statistical Comparison
Data are reported as mean ± standard error of the mean (SEM). Number of
slices (n) and number of animals (N) are indicated in the figure
legends. Before performing statistical comparisons, data were checked
for normality and equal variance using Shapiro-Wilk test and Levene´s
test, respectively. Statistical analysis of gamma oscillations, SW-R and
interneuron counts were performed by one-way-ANOVA followed by posthoc
comparison using Fisher LSD Method when data were normally distributed.
For non-normal data, Kruskal-Wallis One Way Analysis of Variance on
Ranks followed by posthoc comparison using Dunn´s Method was used. The
statistical comparison of IO curves between strains was performed by
two-way repeated measures ANOVA followed by posthoc comparison using
Fisher LSD Method with Greenhouse–Geisser correction (SigmaPlot for
Windows Version 11.0, 2008 or GraphPad Prism, version 9, SD,
California).
