Neuronal growth and synaptic remodeling is dependent on sGC activity. Maximum-intensity Z projections of confocal images of fluorescently labeled B1 and B2 neurons 2 d after axonal injury and treatment with ODQ (Ai, B1, Aii, B2). Aiii, Average total neurite length of B1 and B2 neurons 2 d after axonal injury under control conditions (DIV2+) and in the presence of ODQ (+ ODQ). Groups were compared using NK tests: **p < 0.01; ***p < 0.001. B, Percentage of specific cell pairs showing electrical coupling 2 d after axonal injury under the two experimental conditions (DIV2+, + ODQ) outlined above. n is indicated on the bars. C, Percentage of specific cell pairs showing excitatory chemical coupling 2 d after axonal injury under the two experimental conditions (DIV2+, + ODQ) outlined above. n is indicated on the bars. Scale bars in Ai, Aii, 100 μm.
