a strong trendP = 0.054
There was also a strong trend toward an increase in the overall density of ASPA + cells (Fig. 3e , P = 0.054, n = 4 mice, Welch’s corrected t -test) and a statistically significant 76.1 ± 21.8% increase in the density of newly differentiated EdU + /ASPA + oligodendrocytes in response to neuronal activity stimulation at this later age (Fig. 3b, f , P = 0.017, n = 4 mice, Welch’s corrected t -test).
