1832 M. Faraday in Philos. Trans. (Royal Soc.) 122 139 When the wire is subject to either volta-electric or magneto-electric induction, it appears to be in a peculiar state; for it resists the formation of an electrical current in it... I..have ventured to designate it as the electro-tonic state. This peculiar condition shows no known electrical effects whilst it continues.

1865 J. C. Maxwell in Philos. Trans. (Royal Soc.) 155 468 The facts of the induction of currents as depending on the variations of the quantity called Electromagnetic Momentum, or Electrotonic State, rest on the experiments of Faraday, Felici, etc.

1928 H. Crew Rise Mod. Physics xi. 261 Faraday's views concerning the magnetic field—the electrotonic state as he called it—may be traced in the following paragraphs of his Experimental Researches.

2007 Oxf. Dict. National Biogr. (Electronic ed.) 7 June at Faraday, Michael These observations led him to propose that matter when electrified was in a special state which he named the ‘electrotonic’ state, though he soon abandoned this idea.

1852 H. B. Jones tr. J. H. J. Müller Animal Electr. xxvi. 176 The altered condition of the nerve which is produced by the extraneous current, and which shows its presence by the variation of the electromotive force of the nerve, du Bois-Reymond proposes to call the electrotonic state of the nerve.

1856 B. Haskell Ess. Physiol. Nerv. Syst. i. 13 If any motor nerve be selected which divaricates into two branches..and a galvanic stimulus be applied to either of these branches..the electrotonic state will be developed.

1868 Proc. Royal Soc. 17 386 There are movements of the needle, corresponding perfectly to those which happen in the two electrotonic states, when the experiment is made upon dead nerve and upon other bodies too.

1924 R. S. Lillie in E. V. Cowdry Gen. Cytol. iv. 227 There is here a close analogy to the electrotonic changes of excitability in muscle and nerve.

1975 Brain Res. 84 366 In nervous tissue these low-resistance pathways are referred to as electrotonic synapses at which potential changes spread directly from one cell to another with very short delay.

2007 Jrnl. Electrocardiol. 40 Suppl. No. 1. 69/1 In vivo, there has long been circumstantial evidence for electrotonic coupling of fibroblasts and myocytes in the heart.

1937 Proc. Royal Soc. B. 123 416 The discharge of motor neurones evoked by sensory stimulation is always preceded by a central depolarization of the motor fibres which spreads along the motor roots electrotonically.

1968 Animal Behaviour 16 448/2 The medullary relay neurons are closely coupled electrotonically, and an impulse arising in any one of them rapidly spreads to all the others.

2007 Neurocomputing 70 1675/2 A hyperpolarization propagates electrotonically along the smooth muscle cells of the arteriole.

1867 J. Marshall Outl. Physiol. I. 284 This new condition of the nerve, as regards the electrical state of its molecules, is spoken of as its electrotonicity.

1977 Cell & Tissue Res. 178 165 Related to this proposal is the concept of close membrane apposition and its possible structural relationship to electrotonicity.

2005 Vision Res. 45 777/1 This low density is due, first, to the electrotonicity of the retina being such that phosphenes will interact if electrodes..are too close together.
