>>1550474There is literally nothing anyone can do to that image to recover any information from that image that might have behind the head. That foreground image has completely overwritten the neuron stuff. You could ask an AI or an artist to fill in the head space with an interpretation of what the background might have looked like, but that's not seeing the original model.
>>1550475This image bears only a passing resemblance to the first one. They're recognisable as maybe being one based on the other or both on a common source but if this is the original it's a bad image and the other one modifies it a lot.
The main neuron in this image at the upper middle has a single axon at about 11 o'clock that bifurcates at some distance from the cell body but the other image has an axon that bifurcates near the cell body, possibly as part of what be the axon hillock. This image doesn't even have an axon hillock for a lot of the axons.
At least one of these two images is a complete waste of time because they don't show the same thing, and both of them are wastes of time because there's nothing that can recover the information you want because it was never in those files in the first place.
