==Scientific achievements==
Zeki's scientific achievements include:
* Discovery of the many visual areas of the brain and their functional specialisation for different visual attributes such as colour, motion and form.
* Finding neurons in a part of the [[monkey]] visual system that would respond only when a particular colour, rather than a particular wavelength, was in their [[receptive field]]s. For example, he showed that a red-sensitive [[neuron]] would continue to respond to a red stimulus, even when it was illuminated mainly by green light. This was the first study relating colour perception to single cell physiology in the brain.
* Showing that processing sites in the visual brain are also perceptual sites.
* Showing that we see different attributes of visual input at different times.
* Charting the activity of the brain in time and showing that different visual areas have different activity time courses.
* Studying the neural correlates of subjective mental states, such as love<ref name="love" /> and beauty,<ref name="kawabata2004"/> and more recently, hate.<ref name="hate"/>
