The function (or job) of a neuron in general terms is information
modulation, it depends on the network I'd guess. So, f.i. the neurons of
the retina (eye) might be sending information of an optic flow field nature
(Reichardt detection of speed f.i.) and of some other quality (say
spectrum) in a different setting.
In detail the function of neurons is more complicated, more situational and
complex. Neurons have ion specific channels that control flow of ions
across the neurons membrane. These ion specific channels are regulated
chemically and/or electronically (i.e. depending on the potential across
the membrane). One way of looking at the function of the neuron is f.i. the
sustained capability to modulate ion specific gradients across the membrane.
In short: your question is probably too general to get any satisfactory
