What type is this FlyWire ? (the non hidden one). I’ve seen larger versions of this completed by the lab(s), didn’t think i’d find a non-complete one, lol.
Most probably not any of the Fischbach’s cells. The closest, I could find, were the Lpt cells, but both types visible in the paper are different from yours.
However, your cell is right on the surface of LP and M neuropils and the soma is somewhere deeper in the brain, so maybe it’s classified as something else, than an optic lobe cell.
I think this may be a type of visual projection neuron (VPN). This cell is interesting given that it has axonal terminals in the LP, rather than dendritic terminals so that may affect how it’s identified too.
I agree with KK that this doesn’t seem like an LPT as most that have been analyzed are the giant fiber kind, but I wonder if there are indeed smaller ones…
(Some of the resources I looked at include:
-
This paper analyzes some VPNs here: Visual projection neurons in the Drosophila lobula link feature detection to distinct behavioral programs - PMC
While it doesn’t have an example of your neuron, a VPN fits the description of cells that have a soma “in the cell body rind between optic lobe and central brain”. -
This paper has some figures with a few LPTs, but they also seem to be more dense dendritic types: https://www.biorxiv.org/content/10.1101/2021.12.20.473513v1.full)
thank you for the information! Yeah I’ve also seen the large/gigantic ones and was surprised to 1. find a smaller one. 2 that it wasn’t already completed. lol
what kind of cells is this? i am thinking that the purple one might be a misshaped T4 type, but have no idea what tyoe the red one is

red id think some kind of T cell otherwise idk, purple looks like the ones KK’s been doing w the 90 degrees angled axon.
The ones with the axon were C cells. The purple one isn’t a C cell, because it has its CB in a wrong place. It also isn’t a T4, because they have their soma neurite go through the LP and the CB itself should be in the LP cortex. It might be a Tm cell.
As for the red one - maybe an Lccn2?
aaaand to no one’s surprise i am wrong, lol
lccn2 looks like a good possibility, might be a tm, nothing surpraise me with them
Need some help both IDing and proofing a cell, because it was marked as complete before I added to it, and I’m not 100% that there’s not a weird misalignment situation going on here - but knowing the overall structure I am supposed to be looking at would help.

The branch with a line marked here is the one I added that was merged to another cell.
I’m not sure about it, but I think, the thinner trace might be an LPi cell and the thicker is missing its soma. Because it goes deeper into the central brain, it might not exist in the Fischbach’s paper.
I’m still searching through some papers for these cells, but the thicker cell is putatively a LC-type (lobula columnar cell; maybe LC10d?): FlyWire (I’ve hidden an orange completed friend cell for reference).
The thin one is a lobula cell (could be lobula intrinsic (Li)? not sure). There are bunch of similar completed friends (hidden in the link; yellow is a little bit different and has a separate axonal cluster): FlyWire
Update: Okay, I think that the thin one is a Li-type; probably an Li14. KK previously posted up some examples of putative Li cells from the NEUprint site here: Visual Cell Type Illustrations - #31 by Krzysztof_Kruk Direct link to the Li14 cell here: neuPrintExplorer)
what kind of cell is this? I might ofc be missing something, but have checkhed everything i can think of, and not close too anything i can remember too have seen in that area before.

Judging by its location, it’s probably a Dm (unless it has some missing extensions, but I didn’t find anything). Maybe an underdeveloped Dm4? That type has some twirly branches, just like yours.
Found a couple more extensions. Havent merged in case im wrong. FlyWire where the annotation is there’s a misalignment i cant get past, may nub out may continue idk.
I’ve added some more on top of yours:
https://ngl.flywire.ai/?json_url=https://globalv1.flywire-daf.com/nglstate/5176741022662656
okay this is definitivly starting too look more cell like FlyWire
but probably still miss half of the extensions
did run across this one in the medulla.
not seeing any extension and no idea what kind of cell this two could be, remind me a bit of a lawf, but then i am missing a great many elements + some mergers.

Those are probably Mi cells. I’d say, something from Mi5 - Mi7. Also, the second branch in the light green cell is most probably a merger.
Found you the CBs and some other minor stuff twigs removed that merger on the right of your pic etc: FlyWire
