TL;DR: The morphology and behavior of living exoerythrocytic stages of Plasmodium gallinaceum and P. fallax were studied by the use of tissue cultures, phase contrast microscopy, and time-lapse cinephotomicrography to solve many of the remaining problems concerning exoeriescence stages of malarial parasites and their interrelationships with host cells.
Abstract: The morphology and behavior of living exoerythrocytic stages of Plasmodium gallinaceum and P. fallax were studied by the use of tissue cultures, phase contrast microscopy, and time-lapse cinephotomicrography. The morphology of exoerythrocytic stages of these two species was essentially that previously observed in fixed, stained material, with the following exceptions: (1) the presence of a filament on one end of the merozoite, (2) the absence of clefts in the cytoplasm of the large schizonts, and (3) the absence of a vacuole-like space around the parasite. The following behavior was observed either directly or in time-lapse sequences: (1) emergence of merozoites from mature schizonts, (2) progressive motility of free merozoites, (3) entry of merozoites, both actively and passively, into host cells, (4) nuclear division in the parasite, (5) the various stages of schizogony, including final production of merozoites, (6) massive infection of host cells, and (7) phagocytosis of merozoites and attempted phagocytosis of mature schizonts by macrophages. Exoerythrocytic stages of P. fallax differed from those of P. gallinaceum in that the merozoites of the former were (1) somewhat more curved in shape and (2) present in fewer numbers in mature schizonts. The use of tissue culture, phase contrast microscopy, and time-lapse cinephotomicrography promises to solve many of the remaining problems concerning exoerythrocytic stages of malarial parasites and their interrelationships with host cells.

Journal Article
Abstract: : Five normal and nine labyrinthine defective men were studied in a Slow Rotation Room which produced a change in resultant force of 20 degrees on them The men faced in the direction of rotation and at one minute intervals set a luminous line to the perceived horizontal in darkness for one hour The results for the normal men confirmed an earlier study showing no systematic change in the perception of the visual horizontal after an initial lag effect In contrast, the labyrinthine defective men showed a smaller, rapid, and then a gradual change in the perception of the visual horizontal throughout the one hour of constant rotation At the end of one hour there was no significant difference between the two groups These results are discussed in terms of a differential weighting of the synergistic information available to the two groups (Author)

TL;DR: Two contrasting groups of subjects were studied to determine quantitatively to what extent two visually-enhanced postural equilibrium test performances of labyrinthine defective subjects on a single rail of optimum difficulty become disturbed along the time axis of rotation.
Abstract: Comparative effects of prolonged rotation at 10 rpm on postural equilibrium in vestibular normal and vestibular defective human subjects
