Between 1916 and 1927 he worked at the University of Vienna in neuropathology and neuroanatomy. At the Neurological Institute, his mentors in neuropathology were
Heinrich Obersteiner (1847-1922) and
Otto Marburg (1874-1948). In 1925 Koskinas published, with neurologist
Constantin von Economo (1876-1931), the monumental
Cytoarchitektonik der Hirnrinde des erwachsenen Menschen (
Cytoarchitectonics of the Adult Human Cerebral Cortex). His collaboration with neuropathologist
Ernst Sträussler (1872-1959) in the Psychiatric Clinic headed by
Julius Wagner-Jauregg (1857-1940) lead to several histopathological publications related to the malaria therapy of
dementia paralytica or
general paresis of the insane, a complication of tertiary
syphilis. Following his repatriation to Greece in 1927, he founded private clinics and practised psychiatry and neurology in
Kifissia, a northern Athenian suburb. Koskinas died on 8 July 1975 in Athens at the age of 89. == References ==
