Interestingly I'm sure there was an article I read in a recent TINS
suggesting that there was a lot to be gained to setting up a new branch
of Neuroscience concerning the taxonomy of neurons. This does indicate
the complexities of the subject though. As well as dealing with types of
neuron in vertebrate nervous system, it would deal with invertebrate
Mind you not withstanding all the discussion on this topic,
simple classifications have been atempted, such as classing neurons as
bipolar etc on the basis of structure. The problem is that at the end of
the day such approaches surely amount to little more than what Lord
Rutherford would have called stamp collecting.
