並列摘要

Somatic primary afferent neurons located in dorsal root ganglia and their cranial nerve equivalents have been recognized as not indispensable in sensory transmission for a long period of time. Active
spontaneous activities, extra- and postspike spikes, four response patterns, unusual action potential waveforms, as well as somatovisceral and bilateral activation were shown in the dorsal root ganglion neurons. These findings suggest that synaptical/ junctional activities, dichotomized peripheral processes, somatovisceral and bilateral cross innervation exist in the ganglion. It would thus be tempting to reevaluate its structure and function and restore the nuclear essence of dorsal root ganglion to its original place.
