Separate Area

In 1888, Louis Verrey, a Swiss ophthalmologist, stated emphatically that there is a "centre for the chromatic sense" in the human brain and that it is located in the lingual and fusiform gyri. He did not, however, consider the “colour centre” to be a separate area but a large sub-division of the primary visual cortex. His evidence was quickly dismissed and forgotten. It was not to be taken seriously again until after the experimental discovery of functional specialization in the monkey brain. This paper considers why it is that Verrey did not consider the “colour centre” to be a separate cortical area, distinct from the primary visual cortex, why his evidence was so quickly and effectively dismissed, and why it is that Verrey did not pursue the logic of his findings.
