Both Intra-segmental and Inter-segmental Coordination are Disrupted by Spinal Transections.
(A–D) Polar plots of the normalized phase vector sum (gray circles) of Spinalized (A,B) and Middle-5 (C,D) preparations recorded at two locations at a rostrocaudal offset (A,C) or on the same body segment (B,D). Concentric circles are plotted at distances of 0.33, 0.66 and 1.0 from the fixed point; cross-hairs separate the quadrants. (E) Plot of mean vector sum consistency (r) of the four experimental groups above. * Statistically significant difference.
