Colour Vision: A Fresh View of Lateral Inhibition in Drosophila

Honeybee vision: analysis of orientation and colour in the lateral, dorsal and ventral fields of view

The ability of honeybees (Apis mellifera) to learn and recognise peripherally presented patterns was investigated by training bees in a Y-maze which presented patterns on the side walls, the ceiling or the floor. We found that pattern orientation is learnt and recognised in the lateral and frontal visual field, but not in the dorsal or ventral fields. Colour information, in contrast, is used in...

Colour Vision: Parallel Pathways Intersect in Drosophila

In the last one hundred years, colour vision has been demonstrated in bees and many other insects. But the underlying neural wiring remained elusive. A new study on Drosophila melanogaster combining behavioural and genetic tools yields surprising insights.

Colour Characteristics of Fresh Pork

Lindahl, G. 2005. Colour characteristics of fresh pork. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-7042-0 The objective of the present thesis was to obtain more fundamental understanding of the mechanisms for variations in colour and colour stability of fresh pork. The effects of breed and genotype, including Duroc, Hampshire (three RN alleles), Landrace and Yorkshire pigs, were studied...

A monochrome view of colour

Saunders & van Brakel’s criticism of Berlin & Kay’s methodology misunderstands the fact that scientific hypotheses are tested by generating new, replicable data with novel explanatory power. Thus, although Berlin and Kay studied differences in colour words between languages, the same patterns are also present in colour word usage within languages, in a range of literary and other textual databa...
