(a) Somatosensory cortex layer V pyramidal neuron soma size is reduced in Mecp2−/y mice relative to WT at both P30 (WT: n=124 neurons from 4 mice; Mecp2−/y: n=103 neurons from 4 mice) and P60 (WT: n=126 neurons from 4 mice; Mecp2−/y: n=104 neurons from 4 mice). **p<0.01, unpaired two-tailed Student t-test with Bonferroni correction. Bars represent mean ± SEM.
(b) Somatosensory cortex layer V pyramidal neuron soma size is reduced in Mecp2T158A/y mice relative to WT at both P30 (WT: n=115 neurons from 4 mice; Mecp2T158A/y: n=121 neurons from 4 mice) and P90 (WT: n=81 neurons from 4 mice; Mecp2T158A/y: n=106 neurons from 4 mice). **p<0.01, unpaired two-tailed Student t-test with Bonferroni correction.
