Understanding the brain requires a kind of thinking outside the main tradition of natural science: the biology has to be linked to something intangible, a private experience. Physiologists have recently recorded from neurons that promise to help make the link in the case of colour experience.
متن کاملColour Vision: A Clue to Hue in V2
Where do our brains encode all the colours of the rainbow? We know the neural basis for colour opponency and colour contrast, and recent studies have now provided evidence for the representation of hue in cortical visual area V2.
متن کاملColour Vision and Hue for Autonomous Vehicle Guidance
We explore the use of colour for interpretation of unstructured off-road scenes. The aim is to extract driveable areas for use in an autonomous off-road vehicle in real-time. The terrain is an unstructured tropical jungle area with vegetation, water and red mud roads. We show that hue is both robust to changing lighting conditions and an important feature for correctly interpreting this type of...
متن کاملColour vision in normal subjects tested by the colour arrangement test ‘Roth 28-hue desaturated’
The aim of the study was to obtain normal values for the colour-arrangement test, Roth 28-hue desaturated. In 146 healthy non-smokers colour vision was tested monocularly. The subjects were divided into four age groups: 0-19, 20-39, 40-59, and 60-79 years. The overall error score for all groups was 54 +/- 24 (median +/- mean absolute deviation). The values for the 20-39 year group were signific...
متن کاملEffect of Illumination on Colour Vision Testing with Farnsworth-Munsell 100 Hue Test: Customized Colour Vision Booth versus Room Illumination
PURPOSE To evaluate a customized, portable Farnsworth-Munsell 100 (FM 100) hue viewing booth for compliance with colour vision testing standards and to compare it with room illumination in subjects with normal colour vision (trichromats), subjects with acquired colour vision defects (secondary to diabetes mellitus), and subjects with congenital colour vision defects (dichromats). METHODS Disc...
