Figure 4. New and sprouting axons can be seen to gradually extend within the field of view.

Figure 4

The top panels show an exemplar new axon. The new green axon appeared at week 12, and it continued extending through week 18. The bottom panel shows an exemplar sprouting axon. The pink axon in week 1 has survived PCA treatment. The sprout that extends from this surviving axons axon is first seen in week 6, and it gradually extends through week 9. For both the new and sprouting exemplars, the rightmost panels show a tracing of all axons and the maximal z-projection to provide context.
