| Abstract: | the theory of the colliding impulse method of determining the discharge frequency spectrum and the distribution of fibers by frequency in a mixed nerve trunk is examined. Using the double impulse method, a modification of the colliding impulse method, afferent A -fibers of the aortic nerve in the cat were investigated. Only 61% of these fibers were found to be activated in the initial phase of cardiac ejection when the arterial pressure was 120 mm Hg. Most of the active fibers functioned with a frequency of about 115 spikes/sec.M. V. Lomonosov Moscow State University. Translated from Neirofiziologiya, Vol. 6, No. 3, pp.318–327, May–June, 1974. |
