while these results do not rule out the possibility that subpopulations of projection-neurons defined by dendritic morphology , functional class , or some other parameter are segmentally arranged or that there is a basic modular repetition of neural populations from segment to segment , they do show that projection-neurons as a class and subpopulations of these neurons defined by their dorsal-ventral position are not obviously distributed in a repetitive segmental pattern .
