  • Distribution of GABA‐immunoreactive nerve fibers and cells in the cervical and thoracic paravertebral Sympathetic Trunk of adult rat: Evidence for an ascending feed‐forward inhibition system
    The Journal of comparative neurology, 1993
    Co-Authors: Joachim R. Wolff, Peter Kasa, E. Dobó, H. J. Römgens, Árpád Párducz, Ferenc Joó, A. Wolff
    Abstract:

    Neurochemical and immunohistochemical evidence suggests that the superior cervical ganglion (SCG) contains all components of a gamma-aminobutyric acid (GABA)ergic transmission system, which includes GABAergic axons of unknown origin. The number of nerve fibers with and without GABA-like immunoreactivity was determined in interganglionic connectives at all cervical and thoracic levels of the paravertebral Sympathetic Trunk. In addition, the distribution of GABA-immunoreactive (IR) neurons was established within the ganglion chain and compared with the relative frequency of principal neurons richly innervated by GABA-IR axon terminals. The following results were obtained: (1) the total number of nerve fibers in cross sections did not significantly vary between the cervical levels, but it increased steadily from upper to lower thoracic segments; (2) in contrast, the number of GABA-IR fibers decreased from the cervical Sympathetic Trunk below the SCG (∼300 fibers) down to the seventh to tenth thoracic ganglion, below which no such fiber was seen; (3) GABA-IR nerve fibers originate from a subclass of GABA-IR cells; these are small, bipolar neurons with predominantly ascending, unmyelinated axon-like processes; (4) the number of principal neurons richly innervated by GABA-IR nerve fibers decreased from the SCG to the upper thoracic ganglia, and was very small below; and (5) apart from basket-like innervation, GABA-IR axons also formed diffuse networks around GABA-negative principal neurons predominantly in cervical and upper thoracic ganglia. These data suggest that the GABAergic innervation of paravertebral Sympathetic ganglia is more complex than previously suspected. What appears as preganglionic afferents from several spinal segments (C8-Th7) innervate GABAergic neurons in the Sympathetic Trunk which have ascending axons and focus their inhibitory effects on the cervical Sympathetic ganglia, predominantly the SCG. These data suggest that GABAergic small interganglionic neurons form a feed-forward inhibition system, which may be driven by multisegmental spinal input in the paravertebral Sympathetic ganglion chain. © 1993 Wiley-Liss, Inc.
