The Study of Influenza

W. D. Neff concentrates upon changes in intensity and pattern discrimination and space localization following auditory cortex ablations. Both Galambos and Neff provide data concerning a pathway from the cochlea to the auditory cortex which bypasses the medial geniculate body. G. D. Smirnov compares features of the visual system in amphibians and reptiles, and 0. D. Creutzfelt reviews the extensive analysis of visual cortex neurons by the Freiburg group. The discussion which develops concerning the role of pupil size in habituation of visual cortex evoked responses is of particular interest. D. B. Lindsley considers the relation of visual system electrical events to visual behavior. The continually recurring problem of the relation of unit activity to slow waves in the C.N.S. receives much discussion throughout the monograph. There is excellent continuity throughout the several presentations with only an occasional digression to matters which are not germane to the subject under discussion.
