Term: retinal ganglion cell B

Definition: Sixty-eight neurons with small somata (12-24 micrometers in diameter), small dendritic fields (99-289 micrometers in diameter), and small axonal diameters (04.-07. micrometers in diameter) make up Group RGB.We classified cells with a large soma and a large dendritic field as RGA, cells with a small- to medium-sized soma and a small- to medium-sized dendritic field as RGB, and cells with a small- to medium-sized soma but a medium-to-large dendritic field RGC.
