Morphometrical analysis of types and sub-types of neurons in dorsal root ganglia of the lizard Podarcis sicula.

In the present study, we conducted a morphometrical analysis of the different types and sub-types of lizard DRG neurons at various spinal levels. This analysis demonstrated significant differences in size distribution among the various neuron types and sub-types, as well as a significant shift to greater values in neurons from the dorsal root ganglia at the cervical and the lumbar spinal levels. The results are critically evaluated in relation to methodological issues, and the implications of these findings are discussed.
