  • Title: [Neuronal organization of ganglia in the lumbar region of the cat sympathetic chain].
    Author: Syromiatnikov AV, Lebedev VP, Skok VI.
    Journal: Neirofiziologiia; 1977; 9(5):518-26. PubMed ID: 927598.
    Abstract:
    Neuronal organization of the isolated III--VI ganglia in the lumbar sympathetic chain of the cat was studied by means of intracellular recording. Most of the ganglionic neurons (66%) receive synaptic inputs simultaneously from sympathetic B1-, B2- and C-preganglionic fibres (conduction velocity 12.0 +/- 0.7; 4.4 +/- 0.3 and 1.0 +/- 0.1 m/s respectively). The rest of neurons are activated only by fast-conducting B1- and B2-fibres (24%) or only by slow-conducting C-fibres (10%). The main preganglionic input to the ganglionic neurons comes through the white rami of the rostral segments, the less effective inputs--through the other ones. A part of neurons receive preganglionic C-fibres coming into the ganglia through the grey rami.
