Semir ZEKİ

Semir Zeki (1940-) was a British neuroscientist of Turkish origin who specialized in visual brain and neuroscience. He is known for his work on visual perception, color, movement and form.

Who is Semir Zeki?

One of Semir Zeki's most important studies and discoveries in his field was his discovery that different areas of the visual brain function differently for features such as color, movement and form. This research provided important clues about how the brain processes visual perception. Zeki discovered that in the visual system of monkeys, receptor cells are only sensitive to a specific color or wavelength. For example, the sensitivity of a nerve to red light allows it to continue to show this response even under green light, linking color perception to the cellular function of the brain.

Zeki also showed that visual brain areas are linked not only to perceptual but also to cognitive processes. Another important discovery by Zeki is that visual inputs are processed in different time frames in our brains. This discovery revealed how visual perception is a dynamic process and how the brain processes different visual stimuli in different time frames.

Impact and Legacy

Semir Zeki's influence is felt not only in the world of neuroscience but also in the field of neuroaesthetics. In 2008, he was appointed Professor of Neuroaesthetics at the University of London, where he has done significant work in establishing a scientific link between visual perception and aesthetics. He was subsequently appointed Professor of Neurobiology at the same university. He has studied the neural basis of subjective cognitive states such as love, beauty and hate, investigating how emotional and cognitive processes are shaped in the brain.

Semir Zeki has authored many scientific publications with his studies and findings on the visual brain and has become one of the most recognized names in the field of neuroscience. In addition, his work on visual perception and aesthetics has helped us understand the relationship between art and science.

Today, Zeki's work is an important foundation for the understanding of neuroscience, neuroaesthetics and the visual functions of the brain.
