| It was first induced by applying a brief tetanus of faradic stimulation to the rabbit cortex (Leao, 1944; Bures et al., 1974). Mechanical stimulation, for example, by stroking of the cortical surface with a blunt instrument, a falling weight or even lightly tapping the cortex also initiates SD (Lea˜o [sic], 1944). More recent studies have achieved more reliable and reproducible induction of SD by rapidly inserting and retracting hypodermic steel needles (Lambert et al., 1999; Ebersberger et al., 2001). [...] This model has been shown to be the most reliable stimulus leading to reproducible events on earlier occasions in both non-imaging and imaging studies (Bradley et al., 2001). In any case, changes in extracellular K+ concentration themselves might be involved in such pathophysiological processes in human brain tissue (Mayevsky et al., 1996; Nicholson and Sykova, 1998). SD appears to affect both the neuronal and the glial cells. | The CSD phenomenon is exclusive to the central nervous system (CNS) and appears to involve both the neuronal and the glial cell populations. [...] CSD was first induced by applying a brief tetanus of faradic stimulation to the rabbit cortex (Leão, 1944; Bureš, Buresová & Krivánek, 1974). [...]
Mechanical stimulation, for example, by stroking of the cortical surface with a blunt instrument, a falling weight or even lightly tapping the cortex also evokes CSD (Leão, 1944; Zachar & Zacharová, 1963). More recent studies have achieved more reliable and reproducible induction of CSD by rapidly inserting and retracting hypodermic steel needles (Kaube & Goadsby, 1994; Lambert et al., 1999; Ebersberger et al., 2001), [...] Of available methods KCl has thus proven to be the most reliable stimulus leading to reproducible events on earlier occasions in both non-imaging (Bureš et al., 1974, 1984; Lehmankühler & Richter, 1993; Smith et al., 1998, 2000; Read et al., 1999; Martins-Ferreira et al., 2000; Kuge et al., 2000) and imaging studies (Gardner-Medwin et al., 1994; Latour et al., 1994;Hasegawa et al., 1995; de Crespigny et al., 1996, 1998; James et al., 1999; Bockhorst et al., 2000; Kuge et al., 2000; Bradley et al., 2001, 2002). In any case, changes in extracellular K+ concentration ([K+])o themselves might be involved in such pathophysiological processes in human brain tissue (Mayevsky et al., 1996; Nicholson & Sykova´, 1998). |
