It has been suggested that there are two separate visual streams in the human cerebral cortex: a ventral pathway that provides perceptual representations of the world and serves as a platform for cognitive operations, and a dorsal pathway that transforms visual information for the control of motor acts. Evidence for this distinction comes from(More)
The role of the surface membrane Zn-proteinase in protecting the cellular integrity of the macrophage parasite Leishmania mexicana amazonensis from intraphagolysosomal cytolysis was studied. These cells lose their infectivity to host macrophages after prolonged cultivation in axenic growth medium. The virulent and attenuated variants of the parasite cells(More)
A simple technique is described for producing large-scale, tritanopic displays. The technique reproduces the various phenomena of vision with equiluminous-colour contrast that have previously been reported with red/green stimuli. It is, however, much less demanding technically, robust against artifacts, and can be used on large-scale scenes. One advantage(More)
The virulence of Leishmania mexicana is determined by the concerted action of several parasite molecules. These cells lose their infectivity to host macrophages after prolonged cultivation in axenic growth media. Both virulent and attenuated variants of the parasite cells were cloned. The differential display reverse transcription-polymerase chain reaction(More)
BACKGROUND In this panel, issues deriving from the experience of collaboration between technical specialists and artists are to be outlined and discussed, with reference to the production of the non-screen based interactive new media installation artwork, “Love Object”. The panel is comprised of both artists: Terry1 Bacon, Martin Rieser and Constance(More)
