How many different methods / publications are there on automatic counting of neurons?

I have found that there many methods for counting neurons - either very straightforward (lowish accuracy) imageJ methods, or more advanced methods that use AI etc. (the buzzwod of the decade - that offer very little in how it actually works). I am trying to find as many papers on this as I try and develop a robust, yet simple pipeline, for counting neuron both in vitro and in vivo. Can anyone point me to a resource similar to this? Or suggestions on trying to find an authority in this field? Open to suggestions etc.
