Is there any experience, how a neuron A connected only to a neuron
B find its way to a neuron C more far away?
Assumed A "wants" to "connect" a dentrite to C? How would A find
C? Or, more simple: Assumed A just "connected" to C, how did it
find its way to C? Are there any signs showing up "follow this way
to go to C, follow that way to meet D" or do they just grow along
any existing neuron's extension?
