a: Representative reconstructed d2SPNs from sham and SNI groups. b, A three-dimensional Sholl analysis of reconstructed cNAc d2SPNs showed that the dendritic complexity of cNAc d2SPNs was unchanged by SNI (n = 8 neurons from 5 mice in each group; Mann–Whitney U test with U = 13647, p = 0.6000). c-e, SNI had no effect on the total dendritic length or average spine density of cNAc d2SPNs (n=8 neurons from 5 mice in each group with Mann–Whitney U test; U = 28, p = 0.7023 for c and U = 32, p > 0.9999 for e). Data for b are shown as median with shaded interquartile (quartile 1 to quartile 3); whisker box plots show median, lower and upper quartiles, and whiskers representing minimum and maximum of the data.
