The Lemmon lab studied growth cone behavior for a number of years.  Here are some interesting videos from that time.

This video was made by H. Kamiguchi at RIKEN BSI and is based on the cover photo of his 2000 J. Neuroscience Paper: 

We used interference reflection microscopy to look at how retinal ganglion cell growth cones interact with different adhesion molecules and substrates in a paper by Drazba et al in 1997 in Dev Brain Research 100:183-197

Not a growth cone but a fibroblast

This is a video made by Sue Burden-Gulley of an RGC growth cone growing from laminin to NgCAM/L1cam. It is from her 1995 J Neuroscience paper.  We were very surprised that the growth cone collapsed then rapidly reorganized and ran across the border.  Later on V. Castellani figured out that L1 interacts with neurophilin and this is important in L1 mediated axon guidance.  EMBO 2008
