What type of cell it is?

I agree about TmY1, but the other one might be a new type, because of that double Y part. I’ve found something similar recently:

Tm2? or Tm1a? (or other). Pictured with ID’d Tm2 cells.

Yellow cell in link (annotated point to ID neuron in question).

Tm2. They always have these 2 thick branches projecting towards the inside of the brain. Also, they have flatter arbor in M9, than Tm1.

Any thoughts on this structure as compared to the other tm2 cells?

Considering Tm1a as the alternative rather than Tm1. Also considering axonal termination location.

It looks a little bit different, when looking from the front, but when you see it from the bottom, it looks similar to other ones - a couple of boutons directly at the main branch and a couple distanced a little bit from it.
I’m not sure, how far the differentation between types and subtypes should go, but if it is to be a different type, I’d say, it would be a Tm2a (not existing in Fischbach), because ot the characterstic “top” part.

Edit: Tm1a has it’s bottom medulla part going sideway from the main branch, while Tm1 has the branch go through that arborization. This one hasn’t have that part hanging, so it probably isn’t a Tm1a.

I wonder, it this could be an Mt8

If so, it would probably be the first identified Mt in the dataset (at least, I couldn’t find any).

It looks quite similar to the one shown in Fischbach’s paper, however there’s this proposed projection towards the more proximal brain parts, while this cell, doesn’t have such branch.

it does looks close, but from what i can see in fishback it does looks like the mt8 might be a bit higher in the medula + it does have some twigs going upward from the backbone in medula and not just downward like this one + that second part going out of picture. looks like there are some mt cells missing from the pictures so might be one of them instead or just a variant of mt 8

Any ideas on this curiousity? FlyWire

Looks, like a C3 smashed against a wall.

Agree on C3, weird one.

What type is this? Not familiar with this type. Thnx.

It’s a TmY with a merger around here:

Actually, there’s a double merger. You have to switch branches with the other cell and everything should be ok.

lol, thnx. Removed 6 mergers from this one, guess I missed 1 :sweat_smile:

Not seen this before, FlyWire backbone splits indicating two branches then some ways ‘down’ stream before reaching the dendrites cluster it re-merges into 1 branch. I’m thinking there must be more to this cell I’m missing, I’ll take another look at it tmrw at some point, any1 who wants a crack at it feel free to search around.

Here’s your extension:

It looks, like some kind of a T cell, but not sure which one. It’s “upper” (more distal) part is too low, I think.

lol that was fast and im tired xD, thanks! And yeah it does look like a T cell.

Looks like a C2, but the outer part is completely different and doesn’t have the long projection into lamina.

I’d agree with C2. You’re missing a segment here (will need to be cleaned up from a merger): FlyWire

Thank you! Indeed, that’s it. It looked different because it missed the segment, of course :smiley:
