CSD is an "all-or-none" process and spreads in the manner of a wave through gray matter. CSD appears first at the stimulated site and propagate in all directions at the velocity of 2–3 mm/min, so that increasingly distant areas undergo successively a similar temporary depression. An important characteristic feature of CSD is a propagating negative potential with amplitude of 10–30 mV and duration of more than 30 sec, which may be preceded or succeeded by a positive fluctuation of variable amplitude and duration (figure 2). SD is an "all-or-none" type process and propagates in the manner of a wave through gray matter. SD appears first at the stimulated site and spreads out in all directions at the velocity of 2–3 mm/min, so that increasingly distant areas undergo successively a similar temporary depression. A crucial manifestation of SD is a propagating negative potential with amplitude of 10–30 mV and duration of more than 30 sec, which may be preceded or succeeded by a positive fluctuation of variable amplitude and duration (Figure 1).

CSD can be initiated by different stimuli and so can be directly studied in experimental investigations. It was first induced by applying a brief tetanus of faradic stimulation to the rabbit neocortex by Leao [sic] group (Leao [sic], 1944; Fig. 1). However, such stimuli could lead to convulsive activity spreading from the stimulated area and so subsequent authors preferred to [employ direct current (DC) stimuli (Leao [sic] & Morrison, 1945; Ochs, 1962).] SD can be initiated by different stimuli and so can be directly studied in various in vivo and in vitro experimental models. It was first induced by applying a brief tetanus of faradic stimulation to the rabbit cortex (Leao [sic], 1944; Bures, Buresova & Kriva´nek [sic], 1974; Fig. 1). However, such stimuli could lead to convulsive activity spreading from the stimulated area and so subsequent authors preferred to employ direct current (DC) stimuli (Leao [sic] & Morrison, 1945; Ochs, 1962).
