NB 4-1 generates the Transverse nerve Motoneuron.

These movies are stereo images of NB 4-1 clones.

The top image is a late stage 16 clone; the bottom clone is a mid-stage 17 clone.

3D glasses will enhance the stereo optics, but we find that most viewers can see the three dimensionality at this magnification without the assistance of the glasses.
