Advancements in single cell sequencing technologies have provided a platform by which a comprehensive spinal cord cell type atlas can be achieved. This table serves as a theoretical example of how major characteristics of spinal cord neurons can be integrated to sort cell types into a consistent schema. Similar to the patterns found within the periodic table of elements, this system can reveal organizing principles of cell type relationships and offers a multidimensional view of the complexity behind functional definitions of cell types. As possible examples, “groups” are presented that could correlate with major classes of cell types, such as a dorsal, inhibitory, peptidergic group.
