Hi superneurons and welcome at Eyewire :)
And there are also some awesome tutorial videos made by rprentki:
I hope that'll help you understand what went wrong :-)
Hello, I found this large cylindrical object I really got curious about in a cube I was working on. I temporarily selected it to be seen in 3D view. Anyone got any ideas what this is?
Hey 1206549, that would be a blood vessel.
doesn't look like a normal connection...
Hey Rinda, that looks ok to me actually.
sorry to bother-help received
How do I bypass the tutorial?
Hi. Is it possible for a cell to simply peter out? The one I have stops before it crosses the cube and when I fill in other parts to see what's going on it looks like it's been crowded out by other cells. Can that be right or am I missing something? Thanks.
Sorry, ignore me - have found the walkthroughs now . . .
what the heck is this?
if i am correct, the orange (given) and the pink (mine) connect in the plane shown in the picture. in that case, what are the "arms" doing? they seem to be embracing or someting :-O
You are indeed correct. It's what we call the self-touch, or the good touch. It's probably just wrapping around another cell branch. Looks like two pairs of grappling arms. Anyway, good call!
"self touch", "good touch", eh? are those technical terms? :-D is this is what the nuns warned me about in grammar school?
No religion in the world of neuroscience! haha What we have here is an autapse (the pink part), which is a synapse from a neuron onto itself. I also think they are pretty awesome. Here's the wiki, though there isn't much on it: http://en.wikipedia.org/wiki/Autapse
I went through the cube and can confirm that no children, or branches extend from that autapse. As for loosing the cube, next time you run into a oddity or a section you are unsure about, I'd recommend either tracing it to the best of your ability and submit, or skip over the cube.
that looks like a floating seed (deep blue segs) and axons (light blue segs in the background)
