About the Cover
Cover picture: Extreme stretch growth of integrated
axon tracts (middle) spanning two populations of
neurons (top and bottom). Before the initiation of
stretch growth, the two populations of neurons were
adjacent, bridged by axons that were only~100 μm
long. The bridging axons were progressively stretched
using a microstepper motor system, resulting in a
rapid expansion to 5 cm (shown here) and greater.
Remarkably, axons can be stretch grown at rates of at
least 8 mm per day while maintaining an intact
cytoskeleton. For details, see the article by Pfister et
al. in this issue (pages 7978-7983).
