ok, so I am total newby, never got further than high school biology. Question:
what exactly is the mechanism behind a neuron's decision to fire or not to fire due to a particular event involving signals from some subset of incoming synapses? So suppose there are 100 incoming synapses, and maybe 20 of them fire in some specified way. How does this neuron decide whether to become activated or not? |

are these studies with "2-photon and optical microscopy" very expensive? Or straightforward and cheap? In terms of what is actually happening in the discipline, is studying neural activity with resolution to a single neuron a significant area of research now or is it essentially impractical? What is the typical resolution level in the study of neural system outside the brain?
