After some research work at the Salpêtrière with material from three cases of epidemic encephalitis, the author comes to the conclusion that epidemic encephalitis offers a good opportunity for studying the pathogenesis of sleep. As the infundibular region shows changes and the pituitary seems normal, in encephalitis, Pacheco thinks it more justified to place the sleep center in the infundibular region, as suggested by Claude and Lhermitte, rather than the pituitary, as suggested by Salmon. Marie, under whose auspices the work was conducted, expresses no opinion as to its value, in the introduction.
