Motor map and dendrite expansion at 5 weeks of age. (A) A summary of the motor maps in Supplemental Figure 1 is shown as a heat map. Although map size at 5 weeks of age appears to be smaller than that at 10 weeks of age, the size of the hip area of the WMI group (n = 11) was unchanged compared with control animals (n = 9). (B) The number of blocks in the hip area was unaltered between groups. (C) The threshold for eliciting hip joint twitch was significantly higher in the WMI group. (D) Twenty-seven Golgi-positive neurons per animal were assessed by Sholl analysis in both ipsilateral and contralateral sensorimotor cortex of neonatal WMI model (n = 4) at 5 weeks of age. Sholl analysis revealed that the number of cross sections increased over 60 μm from cell bodies on the right side of the cortex, even at 5 weeks of age. *p < 0.05 and **p < 0.01 by Mann–Whitney U-tests. Data are presented as mean ± SEM.
