Table 2 Statistical data.

From: Longitudinal two-photon imaging in somatosensory cortex of behaving mice reveals dendritic spine formation enhancement by subchronic administration of low-dose ketamine

Data structure

Type of test

p value

Quantification of dendritic spine turnover (n = 11 mice for ketamine group, n = 11 mice for control group), comparison with baseline(0)

Test for normality of data distribution was performed for each data set. In the right-side column of this table, only t-test values are shown for normally distributed data sets, and only Wilcoxon signed rank test values are shown for the remaining data sets.
