Spatial regularity among retinal neurons

For example, in a preparation where most of the relevant neurons are visible, one can learn much about the type-specific characteristics of an unfamiliar mixed set of neurons merely by attempting to assign them to mosaics. The trick is to start by defining arbitrary cell-type criteria that are based ...
