What is the criteria for classifying neurons as small and large? Is this classification based on gross size or the length of axon? Do they have any physiological difference?
For instance it is said that Substantia gelatinosa of Rolando contains small neurons .
What is so special about calling those neurons as such? Aren't they doing the same function of conduction of impulses?
I have googled it but couldn't find any explanation for such naming.
