What type of cell it is?

I found something like this:

https://ngl.flywire.ai/?json_url=https://globalv1.flywire-daf.com/nglstate/6149786893811712

My first guess, would be a merger, but all the backbone branches seem to be ok.
I can’t even tell, what category it is (Tm, TmY, something else?)

@annkri
There are both TmY 3 and Tm 3Y, TmY 5 and Tm 5Y in Fischbach. Not sure, if there are any others like this in other sources.

my very humble guess (and completely uneducated hah) would be a new sub variant or new neuron if 1. it is not a merger which i dont believe it is b/c ive also completed similar cell(s).) and 2. it isnt in the known neuron types catalogue.

Ha, that would be cool :slight_smile:

Dm 5 maybe?

Found this guy 720575940604671404 (completed by lab person w 1/2 thingies missing lol)

My best guess would be a Tm 26 i know it looks like it is a longer axon in the fishback, but the one that is identified lack the axon branch ofc it could be wrongly identified.

It is not supposed to be easy is it? the question is, is the Tm 3Y just some variant of a Tm cell or a completely new type

I’d say, Tm. Because they look like a Tm with only a small projection into LOP. While TmY usually have proportionally larger branches there - reaching at least the first layer.

i found this cell FlyWire

i am thinking it might be a Dm 5 other options are also some kind of Mi cell

You guys are too good! You found this well buried in a blog lol. I was going to make a separate post about it but I guess that can wait now. Hooray for Cell Identification!

One cool stat about the 60,000 neurons in the fly central brain is that a full 30K have cell type info. Each was added by hand by a researcher. But there are 30,000 additional cells with no info!!

You’re welcome to work wherever you like. That said, we’re focusing out efforts in L lobe via the Get Cell button in order to focus on finding the most connected circuitry and work toward one complete optic lobe.

Update from the researchers: no need to add L or R lobe as we can assign this automatically for optic lobe.

Hmm, I don’t think, I’ve ever seen a cell with CB in this place:

Edit:
There are at least a couple of them in that inner “buble” space. Most not completed:

Edit 2:

Found some more (many still needs to be fixed/completed).
I guess, many of them will be C2 and C3. However, I’m not sure, what to think about those, that look like Tm, but have CB in “wrong” place.

I might have skimmed past it accidentally but it looks as if they’ve added a name guide to the blog post.

@Krzysztof_Kruk Nice! In my experience, the type C cells do tend to CB in that area. As for the others…I have nothing to add.

Okay…time for me to join the (type identification) fray, lol:

3 cells in this link:
https://ngl.flywire.ai/?json_url=https://globalv1.flywire-daf.com/nglstate/5314564090494976
am I correct that they are:

  1. Pm3?

  2. An M type? (couldnt find an exact match in the gsheet tab)

  3. Also an M type?

The last 2 are definitely Tm (trans-medulla), because they go all the way through medulla and finish in lobula. If they had a branch to lobula plate, they would be TmY. Usually all these “deformed C” types are "Tm"s.

As for the first one, most probably a Pm, but not sure, which one.

ok, thnx. So if you’re not sure if it’s a Tm1 or 5 etc do you submit an identification as Tm w/o a # or not submit at all?
