Widely accepted hypotheses hold that the primary event responsible for both the initiation and the propagation of SD is the release of some substance from neuronal elements to the extracellular compartment, which initially excites and then depresses adjacent neurons. The slowness of diffusion of the mediator would account for the low velocity of SD propagation. Among the substances proposed to mediate SD propagation are potassium (Grafstein, 1963; Bures et al., 1974) and excitatory amino acids (Fabricius et al., 1993). There are, however, observations that are difficult to reconcile with either of these two propositions.

SD had been interpreted as a composite process or a sequence of several linked events. To solve its genesis, a most important question concerns identification of the very first step in the chain reaction. In the extant literature, however, generally more attention has been given to the major depolarization and the attending extracellular potential shift (AI’,) [sic] than to the antecedent events.

Among the substances proposed to mediate SD propagation are potassium (Grafstein, 1956; Brinley et al., 1960; BureS and Kiivanek, 1960) and excitatory amino acids (Van Harreveld, 1959; SiesjG and Bengtsson, 1989; Fabricius et al., 1993).

The source is not mentioned.

Note, if one takes the online available version of the source and copies (ΔV0) and then pastes that expression, one obtains: (AI’,)
