Unexplained peculiarities of the dorsal root ganglion
Abstract
The cell soma of primary afferent neurons in the dorsal root ganglion (DRG) is assigned by classical neurophysiology the role of a metabolic depot, charged with supporting the peripheral sensory ending, the conducting axon, and the central synaptic terminals. However, certain peculiarities of DRG morphology and physiology do not sit well with this being its only role. For example, why are DRG cell somata electrically excitable, why are some able to fire repetitively on sustained depolarization, and why does the DRG lack a blood-nerve barrier? Consideration of these and related questions leads to several intriguing hypotheses: (1) Electrical excitability of the soma may be required to insure the reliable propagation of impulses past the DRG T-junction and into the spinal cord. (2) Invasion of the afferent spike into the cell soma may provide an essential feedback signal necessary for the cell soma to regulate the excitability of the sensory ending. 3) The subpopulation of DRG neurons that have repetitive firing capability may be responsible for generating the background sensation that we feel as our body schema. Moreover, these neurons may be chemical sensors that provide essential information about our body's internal milieu.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
