If two gratings with a sinusoidal luminance profile are crossed and if each has a different colour then they are seen to alternate; first one dominates and then the other. Part of the time both are seen. The rate of this monocular rivalry varies with the angle between the two gratings. If the two are lined up in parallel the percept is quite stable and remains so until their orientation is about 15° to 20° apart. The rate of alternation then increases rapidly reaching a maximum rate of 30 per minute. The orientational selectivity of the rivalry suggests that the orientational properties of the neurones in the visual cortex discovered by Hubel and Wiesel are involved. Acknowledgements.

The National Health and Medical Research Council has recently issued guidelines on colo-rectal cancer, and givensignificant support to Colorectal Cancer Screening. However, the evidence of cost-effectiveness is inconclusiveaccording to the Cochrane Centre.I argue that it would be wise to undertake trials that are appropriately funded. Otherwise, there is a risk that muchmoney will be spent that cannot subsequently be justified.
