  • The table shows numbers of animals per group with total axonal filament length (±SEM), average number (no.) of branch points (pts) (±SEM), and the resulting average number of branch points per total filament length. Significant differences were observed in these branch point density values in 7–10 week (wk) blocked (blk) mice (*p < 0.05, t = 5.54) and in mice blocked from 7–10 weeks followed by 3 weeks of recovery (*p < 0.05, t = 4.31) compared to controls. No significant difference emerged when branch point densities of mice blocked from 7–10 weeks plus 6 weeks of recovery were compared to controls.
