Most authors who have studied the whole visual system described the fiber connections between the different nuclear centers (Monakow, 1883, 1889; Probst, 1900; Minkowski, 1913, 1920, 1934; Kosaka and Hiraiwa, 1914; Put- nam, 1926; Oshinomi, 1930; Papez and Freeman, 1930; Lashley, 1931, 1934a, 1934b, 1941; Barris and Ingram, 1933/34; Le Gros Clark and Penman, 1934; Waller, 1934; Chang, 1936; Gillilan, 1940; Le Gros Clark, 1942; Krieg, 1946a, 1946b, 1947; Nauta and Bucher, 1954; Hayhow et al. , 1962; Lund, 1966; Mon- tero, 1968). The histogenetic and cytogenetic differentiation of the various...

The experimental brain edema as a result of application of numerous different toxic agents has been the subject of a large number of publications (for synopses see Hirano, 1969; Long et al., 1965). A concept that took the underlying causes of the lesions as the basis for classification of different types of brain edema was presented by Klatzo (1967). In this classification Klatzo differentiates between cytogenic and vasogenic causes of brain edema that are distinguishable from each other by the differing behaviour and reaction of the blood-brain-barrier. The vasogenic type of brain edema is...
