Figure 6. Cluster C cells containing medium to small soma areas and medium to small dendritic fields. A: C1 subcluster contains cells with medium to small soma size and large to medium dendritic fields. B: C2 subcluster contains cells with medium soma sizes and small dendritic fields. C: C3 subcluster contains cells with small soma size and medium dendritic fields. D: C4 subcluster contains the smallest retinal ganglion cells (RGCs) with small soma size and small dendritic fields. E: This is a schematic representation of RGCs showing the possible branching and levels of stratification for the subclusters. INL is the inner nuclear layer; GCL is the ganglion cell layer.
