W. Emerson Exper. in Wks. (1906) I. 183 Nature hates calculators; her methods are saltatory and impulsive. 1894 H. F. Osborn From Greeks to Darwin 200 Another highly characteristic feature of his theory was, that he [St. Hilaire] included in it what has recently been termed ‘saltatory evolution’, and strongly opposed Lamarck's fundamental principle that all transformation is extremely slow. d. Physiology. Used to designate the mode of transmission in a myelinated nerve in which the nerve impulse ‘jumps’ from node to node. ΘΚΠ the world > life > biology > biological processes > action of nervous system > [adjective] > reception or transmission of impulses projectional1852 facilitatory1867 conductive1881 cheirokinaesthetic1900 nociceptive1904 interoceptive1906 photoreceptive1906 proprioceptive1906 adrenotropic1915 photosensory1919 adrenergic1934 saltatory1934 somatotopic1945 psychomotoric1949 supersensitive1949 mechanoreceptive1951 trans-synaptic1954 somatotopical1958 electroreceptive1967 psychomotorical1969 1934 Amer. Jrnl. Physiol. 110 308 The pictures could be accounted for if progression were saltatory and by a process such as Lillie (1925) has described as occurring in the iron wire model... Here, due to reactivation by eddy currents flowing around the segments, activity progresses in jumps from node to node and consequently is more rapid than in the simple model. 1949 Jrnl. Physiol. 108 339 The finding..that a large decrease in node spacing can occur without a drop in conduction velocity is shown not to conflict with the theory of saltatory conduction. 1977 Proc. National Acad. Sci. U.S.A. 74 211/1 Myelinated nerve conducts by transmission of electrical excitation from node to node through local electrical circuits. This ‘saltatory’ mode of conduction results from a discontinuity in the excitability properties of the axon: excitable regions (nodes) alternate with nonexcitable passive core conductors (myelinated internodes). e.

Biology. saltatory replication, a hypothetical evolutionary event in which very many identical copies of a short section of DNA are added to a genome. ΘΚΠ the world > life > biology > biological processes > genetic activity > [noun] > changes or actions of genes or chromosomes > replication > saltatory replication saltatory replication1968 1968 R. J. Britten in Carnegie Inst. Year Bk. 1966–7 72/2 Saltatory replications, the hypothetical events by which families of hundreds of thousands of similar nucleotide sequences are produced in the DNA of an organism... Families are produced in a time short compared to the time required for their loss by divergence (a few hundred million years). 1968 R. J. Britten & Kohne in Carnegie Inst. Year Bk. 1966–7 84/1 Events in which very many copies [of a DNA segment] are made in a short time interval (saltatory replication). Evidence is now available which clearly indicates saltatory replication. 1968 R. J. Britten & Kohne in Carnegie Inst. Year Bk. 1966–7 88/1 A saltatory replication producing 100,000 copies of the right sort of gene is a candidate for a genetic event with immense potentiality. 1970 Nature 12 Dec. 1043/2 Such gene expansion has been designated saltatory replication and is illustrated in Fig. 1 C.
