Anatomical evidence of an indirect pathway for word repetition.

When the anterior and posterior segments of the indirect pathway were analyzed separately, differences between patients and healthy controls were statistically significant for the posterior segment (patients: mean 7.24 ± 2.75; controls: mean 9.14 ± 2.47; t [50] = 2.56, p < 0.05, d = 0.73), while differences in the anterior segment did not reach statistical significance (patients: mean 6.92 ± 3.32; controls: mean 8.64 ± 3.53; t [50] = 1.795, p = 0.079, d = 0.49) ( figure 2 ).
