  • n, Number of cells; Astr, astrocytes; Pyr, pyramidal cells; Int, interneurons. Mann-Whitney U tests and corresponding exact p values. << and <<< indicate significantly smaller with p < 0.01 and <0.001, respectively, with Bonferroni correction for multiple comparisons; n.s., not statistically significant.
