Relationship between Functional and Morphological Properties in Single Primary Afferent Neurons
This report presents data obtained from single primary afferent neurons at two different levels, namely in the dorsal root ganglion (DRG) and in the spinal dorsal horn where the terminal arborizations are formed. The morphology of DRG cells has been the subject of anatomical studies for almost a century (for a review, see Lieberman, 1976). However, many questions remained unsolved, e.g., those concerning the quantitative correlation between soma dimension and axonal conduction velocity, or the presence of axonal branching in or in the vicinity of the ganglion. Since the advent of the technique of intracellular recording and staining of individual cells, these questions have gained new interest and several investigations dealing with these problems have appeared recently.
