Differences in the total spine density between control neurons and those overexpressing NISCH were nominally significant (control, 5.57 ± 0.16 spines per 10 μm; overexpression of NISCH , 6.20 ± 0.26 spines per 10 μm, F (19, 19) = 2.72, df = 38, t = 2.11, P = 0.041, two-tailed Student’s t -tests; Fig. 2 A, B).
