What is it about?
The factors that influence directional growth of nerve cells remain largely mysterious. We serendipitously found that groups of nerve cells (tissue explants) show asymmetric growth in tissue culture. Such asymmetry is not necessary surprising. However, what was surprising is that the orientation of the asymmetry was the same for several explants in the same tissue culture dish. This was not true of individual nerve cells growing separately.

Why is it important?
We are not aware of any prior description of this phenomenon and we do not know the underlying mechanism. One of the intriguing aspects is that this appears to be an emergent property of the nerve tissue.
