| Oct 13, 2017 at 10:29 | comment | added | vkehayas | My comments are here to help you revise your question, so please refrain from starting a conversation in the comments unless something I said is not clear. Your last three comments could be incorporated in the question, IMHO. | |
| Oct 13, 2017 at 10:29 | comment | added | vkehayas | That may happen to some extent (that's why I said mostly), but it's highly unlikely, based on first principles: if it was extensive at all, it would prevent neural migration. Don't confuse "pioneer neurons" and their axons with how you used the term, as they project after they have arrived at their target area. | |
| Oct 13, 2017 at 10:12 | comment | added | Hans-Peter Stricker | For example, it might be the case that some "pioneer" axons connect rather early to their target neuron, then follow it (during its travel) by lengthening, and thus help somehow to guide the following axons (somehow like the emigrant trails led by pioneers in North America in the 19th century), which connect to their targets only later. | |
| Oct 13, 2017 at 9:50 | comment | added | Hans-Peter Stricker | I cannot believe that all neurons have to be at their final positions before synaptogenesis starts. It must be (in my humble opinion), that at least some neurons already connect during their travel to their final positions, so there must also be axon growth just by lengthening, not only guided. But of course I may be wrong. | |
| Oct 13, 2017 at 9:21 | comment | added | Hans-Peter Stricker | The Wikipedia article describes Case 2. But does it explicitly rule out Case 1? | |
| Oct 13, 2017 at 9:20 | comment | added | Hans-Peter Stricker | What do the commissural fibers connect? (See biology.stackexchange.com/questions/65351/…) | |
| Oct 13, 2017 at 9:09 | comment | added | vkehayas | Not an expert on this but Case 1 is mostly wrong. Have you read this: en.wikipedia.org/wiki/Axon_guidance. Also, interhemispheric connections are rather rare, at least in the cortex. | |
