Branch order and Sholl analyses.A, Apical dendritic branch order did not differ among any groups. B, Basilar branch order analysis revealed that IE animals had significantly greater numbers of higher-order branches (i.e., 3rd, 4th, 5th, and 6th-plus). IE had significantly more fifth-order and sixth-order or higher branches compared with all other conditions. Interestingly, IS and SE resulted in elevated third-order branches. C, Basilar Sholl sphere analysis revealed that IE animals had consistently increased the number of branches between 80 and 260 μm away from the cell body. Dendritic branching in the IE condition was significantly elevated between 80 and 160 μm. IS and SE conditions were elevated only at 80 and 100 μm distances. Error bars have been omitted for clarity. *p < 0.05 versus SS; †p < 0.05 versus IS; §p < 0.05 versus SE.
