  • Title: [Analysis of the activity of fibers in an entire nerve trunk and a study of impulse frequency in sympathetic preganglionic fibers].
    Author: Koshelev VB, Leontovich AM, Rodionov IM, Stavskaia ON, Chudakov LI.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1978 Jul; 64(7):935-41. PubMed ID: 680287.
    Abstract:
    The firing rate in type "B" preganglionic sympathetic fibers during strong pressor reactions varied in different fibers from 0 to 80/sec. With an increase of the pressor reaction, the maximum of the density of frequency distribution shifts from 30--40 to 50--60/sec, previously "silent" fibers becoming involved.
